     BACKGROUND 
     Microglia are resident innate immune cells in the brain and are important for the maintenance of homeostatic conditions in the central nervous system. Hickman et al. 2018, Li and Barres 2018. These resident macrophages express a variety of receptors that allow them to sense changes in their microenvironment and alter their phenotypes to mediate responses to invading pathogens, proteotoxic stress, cellular injury, and other infarcts that can occur in health and disease. Id. Microglia reside in the parenchyma of the brain and spinal cord where they interact with neuronal cell bodies (Cserep et al. 2019), neuronal processes (Paolicelli et al. 2011, Ikegami et al. 2019) in addition to other types of glial cells (Domingues et al. 2016, Liddelow et al. 2017, Shinozaki et al. 2017), playing roles in a multitude of physiological processes. With the ability to rapidly proliferate in response to stimuli, microglia characteristically exhibit myeloid cell functions such as phagocytosis, cytokine/chemokine release, antigen presentation, and migration. Colonna and Butovsky 2017. More specialized functions of microglia include the ability to prune synapses from neurons and directly communicate with their highly arborized cellular processes that survey the area surrounding the neuronal cell bodies. Hong et al. 2016, Sellgren et al. 2019. 
     The plasticity of microglia and their diverse states as described through single-cells RNASeq profiling are thought to arise through the integration of signaling from a diverse array of cell surface receptors. Hickman et al. 2013. Collectively known as the microglial “sensome,” these receptors are responsible for transducing activating or activation-suppressing intracellular signaling and include protein families such as Sialic acid-binding immunoglobulin-type lectins (“SIGLEC”), Toll-like receptors (“TLR”), Fc receptors, nucleotide-binding oligomerization domain (“NOD”) and purinergic G protein-coupled receptors. Doens and Fernandez 2014, Madry and Attwell 2015, Hickman and El Khoury 2019. Similar to other cells of the myeloid lineage, the composition of microglial sensomes is dynamically regulated and acts to recognize molecular pattern that direct phenotypic responses to homeostatic changes in the central nervous system (“CNS”). Id. One of the receptors selectively expressed by brain microglia is TREM2, composed of a single-pass transmembrane domain, an extracellular stalk region, and extracellular immunoglobulin variable (“IgV”)-like domain responsible for ligand interaction. Kleinberger et al. 2014. As TREM2 does not possess intracellular signal transduction-mediating domains, biochemical analysis has illustrated that interaction with adaptor proteins DAP10 and DAP12 mediate downstream signal transduction following ligand recognition. Peng et al. 2010, Jay et al. 2017. TREM2/DAP12 complexes in particular act as a signaling unit that can be characterized as pro-activation on microglial phenotypes in addition to peripheral macrophages and osteoclasts. Otero et al. 2012, Kobayashi et al. 2016, Jaitin et al. 2019. In the CNS, signaling through TREM2 has been studied in the context of ligands such as phospholipids, cellular debris, apolipoproteins, and myelin. Wang et al. 2015, Kober and Brett 2017, Shirotani et al. 2019). In mice lacking functional TREM2 expression or expressing a mutated form of the receptor, a core observation is blunted microglial responses to insults such as oligodendrocyte demyelination, stroke-induced tissue damage in the brain, and proteotoxic inclusions in vivo. Cantoni et al. 2015, Wu et al. 2017. 
     Coding variants in the TREM12 locus has been associated with late onset Alzheimer&#39;s disease (“LOAD”) in human genome-wide association studies, linking a loss-of-receptor function to a gain in disease risk. Jonsson et al. 2013, Sims et al. 2017. Genetic variation of other genes selectively expressed by microglia in the CNS, for example, CD33, PLCg2 and MS4A4A/6A have reached genome-wide significance for their association with LOAD risk. Hollingworth et al. 2011, Sims et al. 2017, Deming et al. 2019. Together, these genetic findings link together in a putative biochemical circuit that highlights the importance of microglial innate immune function in LOAD. Additionally, increase or elevation in the soluble form of TREM2 (“sTREM2”) in the cerebrospinal fluid (CSF) of human subjects is associated with disease progression and emergence of pathological hallmarks of LOAD including phosphorylated Tau. Suarez-Calvet et al. 2019. Furthermore, natural history and human biology studies indicate that baseline sTREM2 levels in the CSF can stratify the rate of temporal lobe volume loss and episodic memory decline in longitudinally monitored cohorts. Ewers et al. 2019. 
     In addition to human genetic evidence supporting a role of TREM2 in LOAD, homozygous loss-of-function mutations in TREM12 are causal for an early onset dementia syndrome known as Polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (“PLOSL”) or Nasu-Hakola disease (“NHD”). Golde et al. 2013, Dardiotis et al. 2017. This progressive neurodegenerative disease typically manifests in the 3 rd  decade of life and is pathologically characterized by loss of myelin in the brain concomitant with gliosis, unresolved neuroinflammation, and cerebral atrophy. Typical neuropsychiatric presentations are often preceded by osseous abnormalities, such as bone cysts and loss of peripheral bone density. Bianchin et al. 2004, Madry et al. 2007, Bianchin et al. 2010). Given that osteoclasts of the myeloid lineage are also known to express TREM2, the PLOSL-related symptoms of wrist and ankle pain, swelling, and fractures indicate that TREM2 may act to regulate bone homeostasis through defined signaling pathways that parallel the microglia in the CNS. Paloneva et al. 2003, Otero et al. 2012. The link between TREM2 function and PLOSL has illustrated the importance of the receptor in sustaining key physiological aspects of myeloid cell function in the human body. 
     Efforts have been made to model the biology of TREM2 in mice prompting the creation of TREM2 knock out (“KO”) mice in addition to the LOAD-relevant TREM2 R47H loss-of-function mutant transgenic mice. Ulland et al. 2017, Kang et al. 2018. Although unable to recapitulate the neurological manifestations of PLOSL, TREM2 KO mice show abnormalities in bone ultrastructure. Otero et al. 2012. When the TREM2 KO or mutant mice have been crossed onto familial Alzheimer&#39;s disease transgenic mouse background such as the 5XFAD amyloidogenic mutation lines, marked phenotypes have been observed. Ulrich et al. 2017. These in vivo phenotypes of TREM2 loss-of-function in the CNS include elevated the plaque burden and lower levels of secreted microglial factors SPP1 and Osteopontin that are characteristic of the microglial response to amyloid pathology. Ulland, et al. 2017. Other rodent studies have demonstrated that loss of TREM2 leads to decreased microglial clustering around plaques and emergence of less compact plaque morphology in familial AD amyloid models. Parhizkar et al. 2019. With regards to the Tau protein pathology that is observed in LOAD, familial tauopathy models in mice demonstrated an enhanced spreading of pathological human Tau aggregates from point of injection into mouse brain in TREM2 KO mice. Leyns et al. 2019. Furthermore, single-cell RNASeq studies with the TREM2 KO mice in aged scenarios, 5XFAD familial Alzheimer&#39;s disease model mice, and Amyotrophic Lateral Sclerosis SOD1 mutant mouse backgrounds indicate that TREM2 receptor function is critical for a conserved set of phenotypic transformations within microglial populations in response to CNS pathology. Keren-Shaul et al. 2017. 
     In rodent models where TREM2 expression levels are elevated, brain amyloid pathology in the 5XFAD transgenic mice displayed reduced plaque volume and altered morphology. Lee et al. 2018). The changes in immunohistological markers relating to brain amyloid pathology were also accompanied by an attenuated presence of dystrophic neurites when TREM2 was overexpressed. Id. Therefore, the pharmacological activation of TREM2 is a target of interest for treating or preventing neurological, neurodegenerative and other diseases. Despite many attempts to alter disease progression by targeting the pathological hallmarks of LOAD through anti-amyloid and anti-Tau therapeutics, there is a need for activators of TREM2 to address the genetics-implicated neuroimmune aspects of, for example, LOAD. Such TREM2 activators may be suitable for use as therapeutic agents and remain in view of the significant continuing societal burden that remains unmitigated for diseases, such as Alzheimer&#39;s disease.

The amount of compound in compositions of this disclosure is such that it is effective to measurably activate a TREM2 protein, or a mutant thereof, in a biological sample or in a patient. In certain embodiments, the amount of compound in compositions of this disclosure is such that it is effective to measurably activate a TREM2 protein, or a mutant thereof, in a biological sample or in a patient. In certain embodiments, a composition of this disclosure is formulated for administration to a patient in need of such composition. In some embodiments, a composition of this disclosure is formulated for oral administration to a patient. 
     Compositions of the present disclosure may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. The term “parenteral” as used herein includes subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional and intracranial injection or infusion techniques. Preferably, the compositions are administered orally, intraperitoneally or intravenously. Sterile injectable forms of the compositions of this disclosure may be aqueous or oleaginous suspension. These suspensions may be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer&#39;s solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. 
     For this purpose, any bland fixed oil may be employed including synthetic mono- or di-glycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents that are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation. 
     Pharmaceutically acceptable compositions of this disclosure may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents may also be added. 
     Alternatively, pharmaceutically acceptable compositions of this disclosure may be administered in the form of suppositories for rectal administration. These can be prepared by mixing the agent with a suitable non-irritating excipient that is solid at room temperature but liquid at rectal temperature and therefore will melt in the rectum to release the drug. Such materials include cocoa butter, beeswax and polyethylene glycols. 
     Pharmaceutically acceptable compositions of this disclosure may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, including diseases of the eye, the skin, or the lower intestinal tract. Suitable topical formulations are readily prepared for each of these areas or organs. 
     Topical application for the lower intestinal tract can be effected in a rectal suppository formulation (see above) or in a suitable enema formulation. Topically-transdermal patches may also be used. 
     For topical applications, provided pharmaceutically acceptable compositions may be formulated in a suitable ointment containing the active component suspended or dissolved in one or more carriers. Carriers for topical administration of compounds of this disclosure include, but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol, polyoxyethylene, polyoxypropylene compound, emulsifying wax and water. Alternatively, provided pharmaceutically acceptable compositions can be formulated in a suitable lotion or cream containing the active components suspended or dissolved in one or more pharmaceutically acceptable carriers. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water. 
     For ophthalmic use, provided pharmaceutically acceptable compositions may be formulated as micronized suspensions in isotonic, pH adjusted sterile saline, or, preferably, as solutions in isotonic, pH adjusted sterile saline, either with or without a preservative such as benzylalkonium chloride.

     Without wishing to be bound by any particular theory, the following is noted: TREM2 has been implicated in several myeloid cell processes, including phagocytosis, proliferation, survival, and regulation of inflammatory cytokine production. Ulrich and Holtzman 2016. In the last few years, TREM2 has been linked to several diseases. For instance, mutations in both TREM2 and DAP12 have been linked to the autosomal recessive disorder Nasu-Hakola Disease, which is characterized by bone cysts, muscle wasting and demyelination phenotypes. Guerreiro et al. 2013. More recently, variants in the TREM2 gene have been linked to increased risk for Alzheimer&#39;s disease (AD) and other forms of dementia including frontotemporal dementia. Jonsson et al. 2013, Guerreiro, Lohmann et al. 2013, and Jay, Miller et al. 2015. In particular, the R47H variant has been identified in genome-wide studies as being associated with increased risk for late-onset AD with an overall adjusted odds ratio (for populations of all ages) of 2.3, second only to the strong genetic association of ApoE to Alzheimer&#39;s. The R47H mutation resides on the extracellular 1 g V-set domain of the TREM2 protein and has been shown to impact lipid binding and uptake of apoptotic cells and Abeta (Wang et al. 2015; Yeh et al. 2016), suggestive of a loss-of-function linked to disease. Further, postmortem comparison of AD patients&#39; brains with and without the R47H mutation are supportive of a novel loss-of-microglial barrier function for the carriers of the mutation, with the R47H carrier microglia putatively demonstrating a reduced ability to compact plaques and limit their spread. Yuan et al. 2016. Impairment in microgliosis has been reported in animal models of prion disease, multiple sclerosis, and stroke, suggesting that TREM2 may play an important role in supporting microgliosis in response to pathology or damage in the central nervous system. Ulrich and Holtzman 2016. In addition, knockdown of TREM2 has been shown to aggravate a-syn-induced inflammatory responses in vitro and exacerbate dopaminergic neuron loss in response to AAV-SYN in vivo (a model of Parkinson&#39;s disease), suggesting that impaired microglial TREM2 signaling exacerbates neurodegeneration by modulating microglial activation states. Guo et. al. 2019. A variety of animal models also suggest that Toll-Like Receptor (TLR) signaling is important in the pathogenesis of Rheumatoid Arthritis (RA) via persistent expression of pro-inflammatory cytokines by macrophages. Signaling through TREM2/DAP12 inhibits TLR responses by reducing MAPK (Erk1/2) activation, suggesting that TREM2 activation may act as a negative regulator of TLR driven RA pathogenesis. Huang and Pope 2009. 
     In view of the data indicating that deficits in TREM2 activity affect macrophage and microglia function, the compounds disclosed herein are of particular use in disorders, such as those described above and in the embodiments that follow and in neurodegenerative disorders more generally.

     CSF1R 
     CSF1R is a cell-surface receptor primarily for the cytokine colony stimulating factor 1 (CSF-1), also known until recently as macrophage colony-stimulating factor (M-CSF), which regulates the survival, proliferation, differentiation and function of mononuclear phagocytic cells, including microglia of the central nervous system. CSF1R is composed of a highly glycosylated extracellular ligand-binding domain, a trans-membrane domain and an intracellular tyrosine-kinase domain. Binding of CSF-1 to CSF1R results in the formation of receptor homodimers and subsequent auto-phosphorylation of several tyrosine residues in the cytoplasmic domain, notably Syk. In the brain, CSF1R is predominantly expressed in microglial cells. It has been found that microglia in CSF1R+/− patients are depleted and show increased apoptosis (Oosterhof et al., 2018). 
     The present invention relates to the unexpected discovery that administration of a TREM2 agonist can rescue the loss of microglia in cells having mutations in CSF1R. It has been previously shown that TREM2 agonist antibody 4D9 increases ATP luminescence (a measure of cell number and activity) in a dose dependent manner when the levels of M-CSF in media are reduced to 5 ng/mL (Schlepckow et al, EMBO Mol Med., 2020) and that TREM2 agonist AL002c increases ATP luminescence when M-CSF is completely removed from the media (Wang et al, J. Exp. Med.; 2020, 217(9): e20200785). This finding suggests that TREM2 agonism can compensate for deficiency in CSF1R signaling caused by a decrease in the concentration of its ligand. In a 5×FAD murine Alzheimer&#39;s disease model of amyloid pathology, doses of a CSF1R inhibitor that almost completely eliminate microglia in the brains of wild-type animals show surviving microglia clustered around the amyloid plaques (Spangenberg et al, Nature Communications 2019). Plaque amyloid has been demonstrated in the past to be a ligand for TREM2, and it has been shown that microglial engagement with amyloid is dependent on TREM2 (Condello et al, Nat Comm., 2015). The present invention relates to the unexpected discovery that it is activation of TREM2 that rescued the microglia in the presence of the CSF1R inhibitor, and that this effect is also observed in patients suffering from loss of microglia due to CSF1R mutation. This discovery has not been previously taught or suggested in the available art. 
     To date, no prior study has shown that TREM2 agonism can rescue the loss of microglia in cells where mutations in the CSF1R kinase domain reduce CSF1R activity, rather than the presence of a CSF1R inhibitor or a deficiency in CSF1R ligand. Furthermore, no prior study has taught or suggested that reversal of the loss of microglia due to a CSF1R mutation through TREM2 agonism can be used to treat a disease or disorder caused by and/or associated with a CSF1R mutation. 
     Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), previously recognized as hereditary diffuse leukoencephalopathy with axonal spheroids (HDLS) or pigmentary orthochromatic leukodystrophy (POLD), is an autosomal-dominant central nervous system disease that manifests in the form of variable behavioral, cognitive and motor function changes in patients suffering from the disease. ALSP is characterized by patchy cerebral white matter abnormalities visible by magnetic resonance imaging. However, the clinical symptoms and MRI changes are not specific to ALSP and are common for other neurological conditions, including Nasu-Hakola disease (NHD) and AD, making diagnosis and treatment of ALSP very difficult. 
     Recent studies have discovered that ALSP is a Mendelian disorder in which patients carry a heterozygous loss of function mutation in the kinase domain of CSF1R, suggesting a reduced level of signaling on the macrophage colony-stimulating factor (M-CSF)/CSF1R axis (Rademakers et al, Nat Genet 2012; Konno et al, Neurology 2018). In one aspect, the present invention relates to the surprising discovery that activation of the TREM2 pathway can rescue the loss of microglia in CSF1R+/−ALSP patients, preventing microglia apoptosis, thereby treating the ALSP condition.

     ABCD1 
     The ABCD1 gene provides instructions for producing the adrenoleukodystrophy protein (ALDP). ABCD1 (ALDP) maps to Xq28. ABCD1 is a member of the ATP-binding cassette (ABC) transporter superfamily. The superfamily contains membrane proteins that translocate a wide variety of substrates across extra- and intracellular membranes, including metabolic products, lipids and sterols, and drugs. ALDP is located in the membranes of cell structures called peroxisomes. Peroxisomes are small sacs within cells that process many types of molecules. ALDP brings a group of fats called very long-chain fatty acids (VLCFAs) into peroxisomes, where they are broken down. As ABCD1 is highly expressed in microglia, it is possible that microglial dysfunction and their close interaction with other cell types actively participates in neurodegenerative processes (Gong et al., Annals of Neurology. 2017; 82(5):813-827.). It has been shown that severe microglia loss and damage is an early feature in patients with cerebral form of x-linked ALD (cALD) carrying ABCD1 mutations (Bergner et al., Glia. 2019; 67: 1196-1209). It has also been shown that ABCD1-deficiency leads to an impaired plasticity of myeloid lineage cells that is reflected in incomplete establishment of anti-inflammatory responses, thus possibly contributing to the devastating rapidly progressive demyelination in cerebral adrenoleukodystrophy (Weinhor et al., BRAIN 2018: 141; 2329-2342). These findings emphasize microglia/monocytes/macrophages as crucial therapeutic targets for preventing or stopping myelin destruction in patients with X-linked adrenoleukodystrophy. 
     The present invention relates to the unexpected discovery that administration of a TREM2 agonist can rescue the loss of microglia in cells having mutations in the ABCD1 gene. It has been previously shown that TREM2 agonist antibody 4D9 increases ATP luminescence (a measure of cell number and activity) in a dose dependent manner when the levels of M-CSF in media are reduced to 5 ng/mL (Schlepckow et al, EMBO Mol Med., 2020) and that TREM2 agonist AL002c increases ATP luminescence when M-CSF is completely removed from the media (Wang et al, J. Exp. Med.; 2020, 217(9): e20200785). This finding suggests that TREM2 agonism can compensate for deficiency in ABCD1 function leading to sustained activation, proliferation, chemotaxis of microglia, maintenance of anti-inflammatory environment and reduced astrocytosis caused by a decrease in ABCD1 and accumulation of VLCFAs. The present invention relates to the unexpected discovery that activation of TREM2 can rescue the microglia in the presence of the ABCD1 mutation and an increase in VLCFA, and that this effect may be also observed in patients suffering from loss of microglia due to ABCD1 mutation. This discovery has not been previously taught or suggested in the available art. 
     To date, no prior study has shown that TREM2 agonism can rescue the loss of microglia in cells where mutations in the ABCD1 and a VLCFA increase is present. No prior study has taught or suggested that reversal of the loss of microglia due to an ABCD1 mutation through TREM2 agonism can be used to treat a disease or disorder caused by and/or associated with an ABCD1 mutation.

     Autism Spectrum Disorders 
     It has been found that TREM2 deficient mice exhibit symptoms reminiscent of autism spectrum disorders (ASDs) (Filipello et al., Immunity, 2018, 48, 979-991). It has also been found that microglia depletion of the autophagy Aatg7 gene results in defective synaptic pruning and results in increased dendritic spine density, and abnormal social interaction and repetitive behaviors indicative of ASDs (Kim, et al., Molecular Psychiatry, 2017, 22, 1576-1584.). Further studies have shown that increased dendritic spin density detected in post-mortem ASD brains, likely caused by defective synaptic pruning, results in circuit hypoconnectivity and behavioral defects and are a potential origin of a number of neurodevelopmental diseases (Tang, et al., Neuron, 2014, 83, 1131-1143). Without intending to be limited to any particular theory, these findings suggest that TREM2 activation can reverse microglia depletion, and therefore correct the defective synaptic pruning that is central to neurodevelopmental diseases such as ASDs. The present invention relates to the unexpected discovery that activation of TREM2, using a compound of the present invention, can rescue microglia in subjects suffering from an ASD. This discovery has not been previously taught or suggested in the available art.

     Definitions 
     The following definitions are provided to assist in understanding the scope of this disclosure. 
     Unless otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification or claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the standard deviation found in their respective testing measurements. 
     As used herein, if any variable occurs more than one time in a chemical formula, its definition on each occurrence is independent of its definition at every other occurrence. If the chemical structure and chemical name conflict, the chemical structure is determinative of the identity of the compound. 
     As used herein, the following definitions shall apply unless otherwise indicated. For purposes of this disclosure, the chemical elements are identified in accordance with the Periodic Table of the Elements, CAS version, Handbook of Chemistry and Physics, 101 st  Ed. Additionally, general principles of organic chemistry are described in “Organic Chemistry”, Thomas Sorrell, University Science Books, Sausalito: 2005, and “March&#39;s Advanced Organic Chemistry: Reactions Mechanisms and Structure”, 8 th  Ed., Ed.: Smith, M. B., John Wiley &amp; Sons, New York: 2019, the entire contents of which are hereby incorporated by reference. 
     Stereoisomers 
     The compounds of the present disclosure may contain, for example, double bonds, one or more asymmetric carbon atoms, and bonds with a hindered rotation, and therefore, may exist as stereoisomers, such as double-bond isomers (i.e., geometric isomers (E/Z)), enantiomers, diastereomers, and atropoisomers. Accordingly, the scope of the instant disclosure is to be understood to encompass all possible stereoisomers of the illustrated compounds, including the stereoisomerically pure form (for example, geometrically pure, enantiomerically pure, diastereomerically pure, and atropoisomerically pure) and stereoisomeric mixtures (for example, mixtures of geometric isomers, enantiomers, diastereomers, and atropoisomers, or mixture of any of the foregoing) of any chemical structures disclosed herein (in whole or in part), unless the stereochemistry is specifically identified. 
     If the stereochemistry of a structure or a portion of a structure is not indicated with, for example, bold or dashed lines, the structure or portion of the structure is to be interpreted as encompassing all stereoisomers of it. If the stereochemistry of a structure or a portion of a structure is indicated with, for example, bold or dashed lines, the structure or portion of the structure is to be interpreted as encompassing only the stereoisomer indicated. For example, 5-(4-chloro-2-fluorophenyl)-7-((2S)-2-(1-(1-fluoroethyl)-1H-pyrazol-4-yl)-4-morpholinyl)-2,3-dimethylpyrido[4,3-d]pyrimidin-4(3H)-one (Example 129) is meant to encompass 5-(4-chloro-2-fluorophenyl)-7-((2S)-2-(1-((S)-1-fluoroethyl)-1H-pyrazol-4-yl)-4-morpholinyl)-2,3-dimethylpyrido[4,3-d]pyrimidin-4(3H)-one and 5-(4-chloro-2-fluorophenyl)-7-((2S)-2-(1-((R)-1-fluoroethyl)-1H-pyrazol-4-yl)-4-morpholinyl)-2,3-dimethylpyrido[4,3-d]pyrimidin-4(3H)-one. A bond drawn with a wavy line indicates that both stereoisomers are encompassed. This is not to be confused with a wavy line drawn perpendicular to a bond which indicates the point of attachment of a group to the rest of the molecule. 
     The term “stereoisomer” or “stereoisomerically pure” compound as used herein refers to one stereoisomer (for example, geometric isomer, enantiomer, diastereomer and atropoisomer) of a compound that is substantially free of other stereoisomers of that compound. For example, a stereoisomerically pure compound having one chiral center will be substantially free of the mirror image enantiomer of the compound and a stereoisomerically pure compound having two chiral centers will be substantially free of the other enantiomer and diastereomers of the compound. A typical stereoisomerically pure compound comprises greater than about 80% by weight of one stereoisomer of the compound and equal or less than about 20% by weight of other stereoisomers of the compound, greater than about 90% by weight of one stereoisomer of the compound and equal or less than about 10% by weight of the other stereoisomers of the compound, greater than about 95% by weight of one stereoisomer of the compound and equal or less than about 5% by weight of the other stereoisomers of the compound, or greater than about 97% by weight of one stereoisomer of the compound and equal or less than about 3% by weight of the other stereoisomers of the compound. 
     This disclosure also encompasses the pharmaceutical compositions comprising stereoisomerically pure forms and the use of stereoisomerically pure forms of any compounds disclosed herein. Further, this disclosure also encompasses pharmaceutical compositions comprising mixtures of stereoisomers of any compounds disclosed herein and the use of said pharmaceutical compositions or mixtures of stereoisomers. These stereoisomers or mixtures thereof may be synthesized in accordance with methods well known in the art and methods disclosed herein. Mixtures of stereoisomers may be resolved using standard techniques, such as chiral columns or chiral resolving agents. See, for example, Jacques et al., Enantiomers, Racemates and Resolutions (Wiley-Interscience, New York, 1981); Wilen et al., Tetrahedron 33:2725; Eliel, Stereochemistry of Carbon Compounds (McGraw-Hill, N Y, 1962); and Wilen, Tables of Resolving Agents and Optical Resolutions, page 268 (Eliel, Ed., Univ. of Notre Dame Press, Notre Dame, Ind., 1972). 
     Tautomers 
     As known by those skilled in the art, certain compounds disclosed herein may exist in one or more tautomeric forms. Because one chemical structure may only be used to represent one tautomeric form, it will be understood that for convenience, referral to a compound of a given structural formula includes other tautomers of said structural formula. 
     For example, the following is illustrative of tautomers of the compounds of Formula I, wherein R 1  is H:

     Further, the scope of the present disclosure includes all pharmaceutically acceptable isotopically-labelled compounds of the compounds disclosed herein, such as the compounds of Formula I, wherein one or more atoms are replaced by atoms having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes suitable for inclusion in the compounds disclosed herein include isotopes of hydrogen, such as  2 H and  3 H, carbon, such as  11 C,  13 C and  14 C, chlorine, such as  36 Cl, fluorine, such as  18 F, iodine, such as  123 I and  125 I, nitrogen, such as  13 N and  15 N, oxygen, such as  15 O,  17 O and  18 O, phosphorus, such as  32 P, and sulphur, such as  35 S. Certain isotopically-labelled compounds of Formula I, for example, those incorporating a radioactive isotope, are useful in drug and/or substrate tissue distribution studies. The radioactive isotopes tritium ( 3 H) and carbon-14 ( 14 C) are particularly useful for this purpose in view of their ease of incorporation and ready means of detection. Substitution with isotopes such as deuterium ( 2 H or D) may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be advantageous in some circumstances. Substitution with positron emitting isotopes, such as  11 C,  18 F,  15 O and  13 N, can be useful in Positron Emission Topography (PET) studies, for example, for examining target occupancy. Isotopically-labelled compounds of the compounds disclosed herein can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanying General Synthetic Schemes and Examples using an appropriate isotopically-labelled reagent in place of the non-labelled reagent previously employed.

     General Analytical and Purification Methods 
     Provided in this section are descriptions of the general analytical and purification methods used to prepare the specific compounds provided herein. 
     Chromatography: 
     Unless otherwise indicated, crude product-containing residues were purified by passing the crude material or concentrate through either a Biotage brand silica gel column pre-packed with flash silica (SiO 2 ) or reverse phase flash silica (C18) and eluting the product off the column with a solvent gradient as indicated. For example, a description of silica gel (0-40% EtOAc/hexane) means the product was obtained by elution from the column packed with silica using a solvent gradient of 0% to 40% EtOAc in hexanes. 
     Preparative HPLC Method: 
     Where so indicated, the compounds described herein were purified via reverse phase HPLC using Waters Fractionlynx semi-preparative HPLC-MS system utilizing one of the following two HPLC columns: (a) Phenominex Gemini column (5 micron, C18, 150×30 mm) or (b) Waters X-select CSH column (5 micron, C18, 100×30 mm). 
     A typical run through the instrument included: eluting at 45 mL/min with a linear gradient of 10% (v/v) to 100% MeCN (0.1% v/v formic acid) in water (0.1% formic acid) over 10 minutes; conditions can be varied to achieve optimal separations. 
     Proton NMR Spectra: 
     Unless otherwise indicated, all  1 H NMR spectra were collected on a Bruker NMR Instrument at 300, 400 or 500 Mhz. Where so characterized, all observed protons are reported as parts-per-million (ppm) downfield from tetramethylsilane (TMS) using the internal solvent peak as reference. 
     Mass Spectra (MS) 
     Unless otherwise indicated, all mass spectral data for starting materials, intermediates and/or exemplary compounds are reported as mass/charge (m/z), having an [M+H] +  molecular ion. The molecular ion reported was obtained by electrospray detection method (commonly referred to as an ESI MS) utilizing a Waters Acquity UPLC/MS system. Compounds having an isotopic atom, such as bromine and the like, are generally reported according to the detected isotopic pattern, as appreciated by those skilled in the art. 
     Compound Names 
     The compounds disclosed and described herein have been named using the IUPAC naming function provided with Biovia Pipeline Pilot. 
     Specific Examples 
     Provided in this section are the procedures to synthesize specific examples of the compounds provided herein. All starting materials are either commercially available from Merck Sigma-Aldrich Inc., unless otherwise noted, or known in the art and may be synthesized by employing known procedures using ordinary skill. 
     Synthesis of Examples 
     Method 1 
     Example 1: 5-(4-chloro-2-fluorophenyl)-2,3-dimethyl-7-((2S)-2-(1-methyl-1H-pyrazol-4-yl)-4-morpholinyl)pyrido[4,3-d]pyrimidin-4(3H)-one 
     
       
         
         
             
             
         
       
     
     Step 1: 5,7-dichloro-2,3-dimethylpyrido[4,3-d]pyrimidin-4(3H)-one. To a 10-L four necked round-bottomed flask was added 4-amino-2,6-dichloronicotinic acid 2,2,2-trifluoroacetic acid salt (110 g, 343 mmol) and acetic anhydride (129 mL, 1371 mmol) in pyridine (1100 mL). The reaction was stirred at room temperature for 1 hour. The reaction mixture was cooled to 0° C., and methaneamine (2 M in THF, 1028 mL, 2056 mmol) was added dropwise. The cold bath was removed, and the reaction was stirred for 30 min. The mixture was cooled to 0° C. and 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide (50% in EtOAc solution) (550 mL, 685 mmol) was added. The cold bath was removed, and the reaction was stirred for 1 hour and the mixture was quenched with water (2.5 L) and extracted with EtOAc (2 L). The organic layer was washed with water (2 L) and brine solution (2.5 L). The organic phase was dried over Na 2 SO 4 , filtered, and concentrated under reduced pressure. The crude material was purified via silica gel chromatography (0-40% EtOAc in hexane) to provide a yellow solid which was dissolved in DCM (500 mL) and precipitated with petroleum ether. The obtained solid was filtered and dried to provide 5,7-dichloro-2,3-dimethylpyrido[4,3-d]pyrimidin-4(3H)-one (60 g, 246 mmol, 71.7% yield) as yellow solid.  1 H NMR (400 MHz, DMSO-d6) δ ppm 7.63 (s, 1H), 3.49 (s, 3H), 2.60 (s, 3H). m/z (ESI, +ive ion): 244.0 (M+H). 
     Step 2: 7-chloro-5-(4-chloro-2-fluorophenyl)-2,3-dimethylpyrido[4,3-d]pyrimidin-4(3H)-one. To a 10-L four necked round-bottomed flask was added 5,7-dichloro-2,3-dimethylpyrido-[4,3-d]pyrimidin-4(3H)-one (100 g, 410 mmol) and (4-chloro-2-fluorophenyl)boronic acid (71.4 g, 410 mmol), 1,4-dioxane (3000 mL), and water (1000 mL). To this mixture was added cesium carbonate (400 g, 1229 mmol) and the reaction mass was purged with nitrogen gas for 10 min. PdCl 2 (dppf)-CH 2 Cl adduct (16.73 g, 20.49 mmol) was added, and the reaction mass was stirred at room temperature for 0.5 h. The reaction mixture was quenched with water (4 L) and extracted with DCM (2×3500 mL). The combined organics were washed with brine solution (4000 mL), dried over Na 2 SO 4 , filtered, and concentrated under reduced pressure. The crude material was absorbed onto a plug of 100-200 mesh silica gel and purified by chromatography through a 100-200 mesh silica gel column, eluting with a gradient of 0% to 40% EtOAc in hexane. The obtained solid was triturated in EtOAc (150 mL), filtered, and washed with dry n-Hexane, to obtain 7-chloro-5-(4-chloro-2-fluorophenyl)-2,3-dimethylpyrido[4,3-d]pyrimidin-4(3H)-one (62.5 g, 185 mmol, 45.1% yield) as a white solid.  1 H NMR (400 MHz, DMSO-d6) δ ppm 7.48-7.71 (m, 1H), 7.45-7.51 (m, 2H), 7.37-7.41 (m, 1H), 3.42 (s, 3H), 2.62 (s, 3H). m/z (ESI, +ive ion): 338.0 (M+H). 
     Step 3: (S)-5-(4-chloro-2-fluorophenyl)-2,3-dimethyl-7-(2-(1-methyl-1H-pyrazol-4-yl)morpholino)pyrido[4,3-d]pyrimidin-4(3H)-one. A 250 mL flask was charged with (S)-2-(1-methyl-1H-pyrazol-4-yl)morpholine (Intermediate 3, 5.93 g, 35.5 mmol), 7-chloro-5-(4-chloro-2-fluorophenyl)-2,3-dimethylpyrido[4,3-d]pyrimidin-4(3H)-one (10 g, 29.6 mmol), DMSO (74 mL) and 1,1′-dimethyl triethylamine (11.47 g, 89 mmol). The reaction was heated to 100° C. for 16 h. The reaction was quenched with water and filtered to provide the crude material. The crude material was purified using silica gel column, eluting with 0 to 100% EtOH/EtOAc (1:3) in heptane. The collected fractions were concentrated and triturated with hot isopropanol to yield (S)-5-(4-chloro-2-fluorophenyl)-2,3-dimethyl-7-(2-(1-methyl-1H-pyrazol-4-yl)morpholino)pyrido[4,3-d]pyrimidin-4(3H)-one (9.91 g, 71.50 yield) as a white solid.

     Step 1: 1-(1-benzyl-1H-pyrazol-4-yl)-2-bromoethan-1-one. To a solution of 1-(1-benzyl-1H-pyrazol-4-yl)ethan-1-one (4.5 g, 22.47 mmol) in DCM (204 mL) was added portion wise mono(N,N,N-trimethylbenzenaminium) tribromide (9.15 g, 23.60 mmol) at room temperature. The reaction mixture was stirred overnight at room temperature. The reaction mixture was diluted with water and the aqueous phase was extracted with DCM. The combined organic phases were dried over MgSO 4 , filtered and solvents were evaporated. The reaction was repeated on the same scale (4.5 g). The combined crude was purified by column chromatography eluting with a gradient of 0 to 30% heptane/EtOAc-EtOH (3/1) to provide 1-(1-benzyl-1H-pyrazol-4-yl)-2-bromoethan-1-one (9.9 g, 35.47 mmol, 79%) as a white solid.  1 H NMR (400 MHz, DMSO-d6) δ ppm 8.65 (s, 1H), 8.05 (s, 1H), 7.27-7.40 (m, 5H), 5.39 (s, 2H), 4.60 (s, 2H). m/z (ESI, +ive ion): 279.0 (M+H) + . 
     Step 2: 2-(benzyl(2-hydroxyethyl)amino)-1-(1-benzyl-1H-pyrazol-4-yl)ethan-1-one. To a solution of 1-(1-benzyl-1H-pyrazol-4-yl)-2-bromoethan-1-one (4.45 g, 15.94 mmol) in THF (46 mL) at 0° C. was slowly added 2-(benzylamino)ethan-1-ol (2.84 g, 18.81 mmol). The reaction mixture was stirred at 0° C. for 1 hour and then at room temperature for 6 h. Water was then added to the reaction mixture and the aqueous phase was extracted with EtOAc (×3). The combined organic phases were dried over MgSO 4 , filtered, and concentrated. The reaction was repeated on the same scale. The combined crude material was absorbed onto a plug of silica gel and purified by chromatography through a silica gel column eluting with a gradient of 0% to 10% DCM/MeOH, to provide 2-(benzyl(2-hydroxyethyl)amino)-1-(1-benzyl-1H-pyrazol-4-yl)ethan-1-one (8.3 g, 23.75 mmol, 75% yield).  1 H NMR (400 MHz, DMSO-d6) δ ppm 8.57 (s, 1H), 7.96 (s, 1H), 7.20-7.31 (m, 10H), 5.36 (s, 2H), 4.44 (t, J=5.2 Hz, 1H), 3.68 (d, J=3.1 Hz, 2H), 3.43-3.53 (m, 4H), 2.60 (d, J=6.2 Hz, 2H). m/z (ESI, +ive ion): 350.0 (M+H) + . 
     Step 3: 2-(benzyl(2-hydroxyethyl)amino)-1-(1-benzyl-1H-pyrazol-4-yl)ethan-1-ol. To a solution of 2-(benzyl(2-hydroxyethyl)amino)-1-(1-benzyl-1H-pyrazol-4-yl)ethan-1-one (8.30 g, 23.75 mmol) in methanol (79 mL) at 0° C. was added sodium tetrahydroborate (1.797 g, 47.5 mmol) portion wise. The reaction mixture was stirred at 0° C. for 30 min and then at room temperature for 2 h. 90% of the solvent was concentrated under vacuo. Ice-cooled water was added dropwise to quench the reaction. The reaction mixture was extracted with EtOAc (×3). The combined organic layer was dried over anhydrous MgSO 4 , filtered and concentrated under reduced pressure. The crude 2-(benzyl(2-hydroxyethyl)amino)-1-(1-benzyl-1H-pyrazol-4-yl)ethan-1-ol (8.35 g, 23.76 mmol, 100% yield) was used as such in the next step.  1 H NMR (400 MHz, DMSO-d6) δ ppm 7.63 (s, 1H), 7.25-7.35 (m, 8H), 7.18-7.24 (m, 3H), 5.26 (s, 2H), 4.82 (d, J=3.8 Hz, 1H), 4.37 (t, J=5.4 Hz, 2H), 3.68 (d, J=3.5 Hz, 2H), 3.40-3.47 (m, 2H), 3.17 (d, J=5.3 Hz, 1H), 2.64 (dd, J=6.4, 4.2 Hz, 4H). m/z (ESI, +ive ion): 352.2 (M+H) + . 
     Step 4: 4-benzyl-2-(1-benzyl-1H-pyrazol-4-yl)morpholine, hydrochloric acid salt. A solution of 2-(benzyl(2-hydroxyethyl)amino)-1-(1-benzyl-1H-pyrazol-4-yl)ethan-1-ol (8.35 g) in 6N HCl (61 mL) was heated at 110° C. for 2 h. The reaction mixture was evaporated to dryness under reduced pressure. The resulting solid was triturated with Et 2 O which afforded 4-benzyl-2-(1-benzyl-1H-pyrazol-4-yl)morpholine as HCl salt. The crude was used in the next step without any further purification.  1 H NMR (400 MHz, DMSO-d6) δ ppm 11.97 (s, 1H), 7.87 (s, 1H), 7.65 (dt, J=7.5, 3.6 Hz, 2H), 7.42-7.51 (m, 4H), 7.31 (dt, J=13.8, 6.7 Hz, 3H), 7.19-7.24 (m, 2H), 5.29 (s, 2H), 4.97 (dd, J=11.1, 2.3 Hz, 1H), 4.27-4.39 (m, 2H), 3.96-4.06 (m, 2H), 3.37 (d, J=12.1 Hz, 1H), 3.14 (dt, J=31.1, 11.0 Hz, 3H). m/z (ESI, +ive ion): 334.2 (M+H) + . 
     Step 5: 2-(1H-pyrazol-4-yl)morpholine. A suspension of 4-benzyl-2-(1-benzyl-1H-pyrazol-4-yl)morpholine as HCl salt (23.75 mmol) and dihydroxypalladium (3.34 g, 4.75 mmol) in ethanol (120 mL) was put under vacuum and flushed with nitrogen. The reaction mixture was flushed with hydrogen and was stirred under hydrogen atm (25 psi) at room temperature for 18 h. The catalyst was removed by filtration over celite and washed with ethanol several times. The solvent was concentrated under vacuum. The crude 2-(1H-pyrazol-4-yl)morpholine was purified by chiral SFC using an AD 30×250 mm, 5 micron column (mobile phase 20% ethanol, 0.2% diethylamine), F=180 mL/min. to provide two isomers as light brown solids. Absolute stereochemistry of Intermediates 1-4 was assigned based on independent synthesis of both stereoisomers of example 1 (pyrazole methylation followed by SnAr coupling) and subsequent x-ray crystallography. The stereochemical indicators for intermediates 5-15 of Table 8 below have been assigned arbitrarily.

     Step 1: Tert-butyl 4,4-difluoro-3-(1-methyl-1H-pyrazol-4-yl)piperidine-1-carboxylate. To a 100-mL round-bottomed flask was added tert-butyl 3-(1-methyl-1H-pyrazol-4-yl)-4-oxopiperidine-1-carboxylate (1 g, 1.647 mmol)) in DCM (40 mL) and DAST (2.2 mL, 16.47 mmol) at 0° C. The reaction mixture was warmed to room temperature, stirred for 48 h. then quenched with 10% sodium bicarbonate (50 mL) and extracted with DCM (30 mL). The organic extract was dried over Na 2 SO 4 . The solution was filtered and concentrated in vacuo to give the crude material as an orange oil.

     Example A1 
     In Vitro Measurement of Triggering Receptor Expressed on Myeloid Cells 2 Activity Using Cellular Phosphorylation of Spleen Tyrosine Kinase (“Syk”) Assays 
     Pharmacological measurements of TREM2 signaling through DAP12 were made with TREM2 and DAP12 overexpressing HEK293 cells stable cell lines that had been single-cell cloned (“TREM2/DAP12-HEK”). The readout of the TREM2 signaling utilized Perkin Elmer AlphaScreen/AlphaLISA technology monitoring the phosphorylation levels of the Syk kinase. TREM2/DAP12-HEK cell lines were cultured in DMEM-F12 (Corning 10-092-CM) supplemented with 1× Penicillin/Streptomycin (Corning 30-002-CI), 1× GlutaMAX (Gibco 35050-061), and 10% Fetal Bovine Serum (Life Technologies 10099) referred to as “HEK Culture Medium”. Suspensions of TREM2/DAP12-HEK cells were prepared in HEK Culture Medium and dispensed into 384-well poly-D-lysine coated microplates (Corning 354661) at a density of 20,000 cells/well using a Multidrop Combi peristaltic microplate dispenser (Thermo), 25 uL volume of cell suspension/well. Plates containing cells were then incubated for 20 hours in a humidified cell culture incubator at 37° C. with 5% CO 2  (Thermo). After incubation, removed culture medium from all wells of each microplate and replaced medium with 20 uL of “Assay Buffer” comprised of DMEM-F12 (Corning 10-092-CM) supplemented with 1× Penicillin/Streptomycin (Corning 30-002-CI) and 0.1% Pluronic F-68 Polyol (MP Biomedical 092750049) using a Bravo 384-well pipette-based liquid handling system (Agilent). Assay Buffer contained diluted test articles (in 1% final DMSO concentration for compounds) or 100 nM anti-human/mouse TREM2 antibody (R&amp;D Systems MAB17291) as a positive control, 100 nM or rat IgG2B isotype Ab as a negative control (R&amp;D Systems MAB0061). Incubated the plates with test articles and controls for 45 minutes at room temperature and then aspirated/removed the medium from each well of the plates. Used a Multidrop Combi peristaltic liquid handler (Thermo) to dispense 15 uL/well of “Cell Lysis Immunoassay Buffer”. The Cell Lysis Immunoassay Buffer contained M-PER Mammalian Protein Extraction Reagent (Pierce/ThermoFisher 78505), 1× Halt Phosphatase Inhibitor Cocktail (ThermoFisher #78427), 0.1875 nM anti-phospho-Syk (Tyr525/526) (C87C1) rabbit mAb (Cell Signaling Technologies catalog #2710), and 1.5 nM biotinylated Mouse anti-human Syk (4D10) antibody (BD Biosciences, catalog #624008). Incubated plates for 1 hour at room temperature after the addition of the Cell Lysis Immunoassay Buffer. Used the Multidrop Combi liquid handler to dispense 15 uL of AlphaScreen Acceptor Bead Solution containing 7.5 μg/mL anti-rabbit IgG (Fc specific) AlphaLISA Acceptor Beads (Perkin Elmer AL104R) in 1× Immunoassay buffer (Perkin Elmer AL000F) to each well of the microplates. Incubated plates for 2 hours at room temperature. Following the incubation with the AlphaLISA Acceptor Bead Solution, used a Multidrop Combi liquid handler (Thermo) to dispense 15 uL of AlphaScreen Donor Bead Solution containing 30 μg/mL of AlphaScreen Streptavidin Donor beads (Perkin Elmer 6760002B) in 1× Immunoassay buffer (Perkin Elmer AL000F) to each well of the microplates. Incubated microplates for 2 hours protected from light sources as the AlphaScreen reagents are light sensitive. Once the final incubation was completed, acquired AlphaScreen signal from the donor and acceptor beads using an Envision high throughput multi-modal microplate reader (Perkin Elmer) calibrated to the plate type with the AlphaScreen mirror and filter-set in 384-well mode, 680 nanometer excitation wavelength. The total measurement time per well was 550 milliseconds with a 180 millisecond excitation time. 
     After reading the AlphaScreen signal for each well of the microplates, on a plate-by-plate basis, each raw test article well value (x) was normalized to a Percent of Control (“POC”) value using the following formula: POC=((x−μ n )/(μ p −μ n ))*100 where (μ n ) is the mean negative control well signal for the given plate and (μ p ) is the mean positive control TREM2 antibody signal for the given plate. Each plate contained 12 of each type of control wells that were used to generate the mean values. For concentration response curve analysis with test articles tested at various concentrations, the % of activation values were analyzed with 4 Parameter Logistic or Sigmoidal Dose-Response Models using GeneData Screener (GeneData, AG) or GraphPad Prism 7 (Graphpad Software, Inc.). The potency of the test item was expressed as EC50 corresponding to the test item concentration able to activate the phospho-Syk AlphaScreen signal to 50% of the maximal response. 
     For pharmacological assessment of TREM2 signaling in cellular systems natively expressing TREM2, human monocyte-derived macrophages were utilized. CD14 +  monocytes positively selected from large-scale apheresis on healthy human donors (Lonza) were differentiated into macrophages in low-attachment bioprocess bags (Saint-Gobain Performance Plastics) for 9 days in RPMI-1640 medium (Gibco 11875093) supplemented with 10% Fetal Bovine Serum (Gibco 10082139), 10 mM HEPES (Gibco 15630080), 1× Penicillin-Streptomycin (Gibco 15140122), 1× Non-essential amino acids (Gibco 11140050), 1 mM Sodium Pyruvate (Gibco 11360070), 1× GlutaMAX (Gibco 35050-061), and 50 ng/mL M-CSF (Promocell C-60442A). After differentiation, macrophages were harvested and cryopreserved in BamBanker (Wako/GC LYMPHOTEC 302-14681/CS-02-001) in addition to undergoing quality control for expression of cell surface markers including TREM2 using flow cytometry. Batches utilized for phospho-Syk assays were approximately 80-90% TREM2 +  by flow cytometry. 
     After cryorecovering macrophages, prepared live cell suspensions of 100,000 cells/mL in “Macrophage pSyk Assay Medium” composed of RPMI-1640 with GlutaMAX medium (Gibco 61870036) supplemented with 10% Fetal Bovine Serum (Gibco 10082139), 10 mM HEPES (Gibco 15630080), 1× Penicillin-Streptomycin (Gibco 15140122), 1× Non-essential amino acids (Gibco 11140050), 1 mM Sodium Pyruvate (Gibco 11360070), and 10 ng/mL M-CSF (Promocell C-60442A). Used a Multidrop Combi peristatic liquid handling instrument (Thermo) to dispense 50 uL/well of cell suspension (5,000 cells/well) into poly-d-lysine coated 384-well plates (Corning 354661). After a 30 minute incubation at room temperature, incubated plates in a humidified cell culture incubator at 37° C. with 5% CO 2  (Thermo) for 16 hours. To initiate assay with test articles, medium in each well of the assay plates was aspirated and replaced with 20 uL Assay Buffer containing diluted test articles (in 1% final DMSO concentration for compounds) or Assay Buffer containing 1% DMSO for as a negative control. The remainder of the macrophage AlphaScreen phospho-Syk assay followed the procedure detailed above for the HEK cell lines. 
     After reading the AlphaScreen signal for each well of the microplates containing macrophages, on a plate-by-plate basis, each raw test article well value (x) was background subtracted from the mean negative control well signal for the given plate. Each plate contained 12-24 negative control wells that were used to generate the mean value for background subtraction. For concentration response curve analysis with the test articles tested at various concentrations, the values were analyzed with a 4 Parameter Logistic curve fit using GraphPad Prism 7 (Graphpad Software, Inc.). The potency of each test item was expressed as EC50 corresponding to the test item concentration able to activate the background subtracted phospho-Syk AlphaScreen signal to 50% of the maximal response.

     Example A2 
     In Vitro Measurement of Triggering Receptor Expressed on Myeloid Cells 2 Activity Using Cellular Phosphorylation of Spleen Tyrosine Kinase (“Syk”) Assays Used for Examples 276-283 
     Measurement of TREM2 agonist potency was done using a HEK cell line expressing human TREM2 and DAP12 (HEK293T-hTREM2 cells). Binding of small molecules to, and activation of, TREM2 increases the phosphorylation of Syk. The resultant levels of Syk phosphorylation were measured using a commercial AlphaLisa reagent kit. To perform the assay, HEK-hTREM2 cells were plated at 14,000 cells per well in a 384 well plate, in 25 μL of complete growth media and incubated at 37° C., 5% CO 2  for 20-24 hours. Prior to the assay, test compounds were diluted in the 384 well plates in assay buffer and allowed to equilibrate for 30 minutes. Growth media was removed from cell plates by inversion on blotting paper, and 25 μL of test compounds in assay buffer was added to cells. Cells were incubated for 45 minutes at room temperature. After 45 minutes, assay buffer was removed and 10 μL of lysis buffer was added. Plates were shaken for 20 minutes at 350 RPM at room temperature. After complete lysis, AlphaLisa reagents were added to the lysate, and fluourescence intensity was measured using a Perkin Elmer Envision plate reader. Intensities were used to generate a standard curve, and % activation was calculated. Curve fitting was performed using Prism v9 software, log(agonist) vs response—variable slope (four parameters), and EC50s were calculated from the curve fit. 
     The results presented in Table 11 have been generated with the in vitro assay described above for Examples 276-283. This assay may be used to test any of the compounds described herein to assess and characterize a compound&#39;s ability to act as an agonist of TREM2. 
     Compounds designated as “A” demonstrated an EC50 of ≤0.05 μM. Compounds designated as “B” demonstrated an EC50&gt;0.05 μM and ≤0.5 μM. Compounds designated as “C” demonstrated an EC50&gt;0.5 μM and ≤3.0 μM. Compounds designated as “D” demonstrated an EC50&gt;3.0 μM and ≤100 μM.
