Context: Impaired spatial working memory is a core cognitive deficit observed in people with 22q11 Deletion syndrome (22q11DS) and has been suggested as a candidate endophenotype for schizophrenia. However, to date, the neuroanatomical mechanisms describing its structural and functional underpinnings in 22q11DS remain unclear. We quantitatively investigate the cognitive processes and associated neuroanatomy of spatial working memory in people with 22q11DS compared to matched controls. We examine whether there are significant between-group differences in spatial working memory using task related fMRI, Voxel based morphometry and white matter fiber tractography.', 'Multimodal magnetic resonance imaging employing functional, diffusion and volumetric techniques were used to quantitatively assess the cognitive and neuroanatomical features of spatial working memory processes in 22q11DS. Twenty-six participants with genetically confirmed 22q11DS aged between 9 and 52 years and 26 controls aged between 8 and 46 years, matched for age, gender, and handedness were recruited.', 'People with 22q11DS have significant differences in spatial working memory functioning accompanied by a gray matter volume reduction in the right precuneus. Gray matter volume was significantly correlated with task performance scores in these areas. Tractography revealed extensive differences along fibers between task-related cortical activations with pronounced differences localized to interhemispheric commissural fibers within the parietal section of the corpus callosum.
Answer: Abnormal spatial working memory in 22q11DS is associated with aberrant functional activity in conjunction with gray and white matter structural abnormalities. These anomalies in discrete brain regions may increase susceptibility to the development of psychiatric disorders such as schizophrenia.

Context: Alloreactive NK cells play a role in tumor eradication after allogeneic HLA mismatched stem cell transplantation (SCT). The effect of NK alloreactivity in HLA identical SCT is still under debate and in particular in transplantation for chronic myeloid leukemia (CML) the data are very limited and with conflicting outcome. The aim of our study was to evaluate the effect of KIR genes and KIR ligands on leukemia free survival (LFS) and relapse rate in a well-defined, homogeneous group of CML patients phase upon HLA identical sibling SCT.', 'We retrospectively analyzed the effect of KIRs and KIR ligands (C1 and C2) on LFS and relapse in 70 CML patients in 1st chronic phase, who had received an HLA identical sibling graft. For KIR typing we used a single PCR based KIR typing protocol that also included primers allowing for the identification of the KIR binding site on HLA-Cw (AA 77 and 80).', 'The data show clear differences in transplant outcome between patients having both ligands (C1 and C2) as compared to patients having only one ligand (C1 or C2). In the latter group, the stimulatory KIR2DS5 gene was associated with improved leukemia free survival (p=0.007; hazard ratio 4.3; 95% confidence interval 1.3-6.7) and lower relapse rates (p=0.028; HR 4.3, 95% CI 1.1-9.1). In contrast, in patients carrying both ligands, KIR2DS5 was associated with reduced LFS (p=0.0056; HR 0.3; 95% CI 0.1-0.7) and higher relapse rate (p=0.02; HR 0.35, 95% CI 0.1-0.8).
Answer: Our data indicate a role for an NK mediated anti-CML response after HLA identical sibling SCT that is influenced by KIR ligands and, more importantly, by stimulatory KIRs present in the donor.

Context: An effective HIV vaccine will likely require induction of both mucosal and systemic cellular and humoral immune responses. We investigated whether intramuscular (IM) delivery of electroporated plasmid DNA vaccine and simultaneous protein vaccinations by intranasal (IN) and IM routes could be combined to induce mucosal and systemic cellular and humoral immune responses to a model HIV-1 CN54 gp140 antigen in mice.', 'Co-immunisation of DNA with intranasal protein successfully elicited both serum and vaginal IgG and IgA responses, whereas DNA and IM protein co-delivery did not induce systemic or mucosal IgA responses. Cellular IFNγ responses were preserved in co-immunisation protocols compared to protein-only vaccination groups. The addition of DNA to IN protein vaccination reduced the strong Th2 bias observed with IN protein vaccination alone. Luminex analysis also revealed that co-immunisation with DNA and IN protein induced expression of cytokines that promote B-cell function, generation of TFH cells and CCR5 ligands that can reduce HIV infectivity.
Answer: These data suggest that while IN inoculation alone elicits both cellular and humoral responses, co-administration with homologous DNA vaccination can tailor these towards a more balanced Th1/Th2 phenotype modulating the cellular cytokine profile while eliciting high-levels of antigen-specific antibody. This work provides insights on how to generate differential immune responses within the same vaccination visit, and supports co-immunisation with DNA and protein by a mucosal route as a potential delivery strategy for HIV vaccines.
