Q: Monocytes are primary targets for human CMV (HCMV) infection and are proposed to be responsible for hematogenous dissemination of the virus. Monocytes acquire different functional traits during polarization to the classical proinflammatory M1 macrophage or the alternative antiinflammatory M2 macrophage. We hypothesized that HCMV induced a proinflammatory M1 macrophage following infection to promote viral dissemination because, biologically, a proinflammatory state provides the tools to drive infected monocytes from the blood into the tissue. To test this hypothesis of monocyte conversion from a normal quiescent phenotype to an inflammatory phenotype, we used Affymetrix Microarray to acquire a transcriptional profile of infected monocytes at a time point our data emphasized is a key temporal regulatory point following infection. We found that HCMV significantly up-regulated 583 (5.2%) of the total genes and down-regulated 621 (5.5%) of the total genes>or=1.5-fold at 4 h postinfection. Further ontology analysis revealed that genes implicated in classical M1 macrophage activation were stimulated by HCMV infection. We found that 65% of genes strictly associated with M1 polarization were up-regulated, while only 4% of genes solely associated with M2 polarization were up-regulated. Analysis of the monocyte chemokinome at the transcriptional level showed that 44% of M1 and 33% of M2 macrophage chemokines were up-regulated. Proteomic analysis using chemokine Ab arrays confirmed the secretion of these chemotactic proteins from HCMV-infected monocytes. Overall, the results identify that the HCMV-infected monocyte transcriptome displayed a unique M1/M2 polarization signature that was skewed toward the classical M1 activation phenotype.

Q: Plasmodium falciparum malaria, an infectious disease caused by a parasitic protozoan, claims the lives of nearly a million children each year in Africa alone and is a top public health concern. Evidence is accumulating that resistance to artemisinin derivatives, the frontline therapy for the asexual blood stage of the infection, is developing in southeast Asia. Renewed initiatives to eliminate malaria will benefit from an expanded repertoire of antimalarials, including new drugs that kill circulating P. falciparum gametocytes, thereby preventing transmission. Our current understanding of the biology of asexual blood-stage parasites and gametocytes and the ability to culture them in vitro lends optimism that high-throughput screenings of large chemical libraries will produce a new generation of antimalarial drugs. There is also a need for new therapies to reduce the high mortality of severe malaria. An understanding of the pathophysiology of severe disease may identify rational targets for drugs that improve survival.

Q: Amyotrophic Lateral Sclerosis (ALS) is a progressive degenerative disease of the motor neurons and the cause is unknown. Diverse factors such as genetic defects, nutritional deficiencies, head trauma, environmental toxin, autoimmune responses and viral and bacterial infections are involved. Mycoplasmas have been implicated as causal agents of different illnesses in human. The purpose of this study was to investigate the presence of mycoplasmas in the bloodstream of patients with ALS. Patients with ALS and healthy individuals were included in the study. A blood sample was taken in tubes with or without anticoagulant. Mycoplasmas were detected by culture or direct PCR, and the presence of antibodies IgM and IgG against LAMPs of these microorganisms by Western blot. Cultures for aerobic facultative bacteria were also done. Blood samples from 13 patients and 44 healthy individuals were screened. All blood cultures for non-fermentative mycoplasmas and aerobic facultative bacteria were negative. Cultures for fermentative mycoplasmas were considered positive after identification of mycoplasmal DNA by PCR. Mycoplasma sp. was detected by culture or direct PCR in 6/13 (46%) patients and in 4/44 (9%) of healthy individuals. M. fermentans was detected by PCR using specific primers in six patients and in two healthy individuals. IgM against LAMPs of M. fermentans were detected in 6/13 (46%) blood samples from patients and in 13/44 (30%) from healthy individuals, while. IgG was detected in 4/13 (31%) patients and in 3/44 (7%) healthy individuals. The results of this study show that mycoplasmas cause a systemic infection and could play a role in the origin or progression of the ALS.
