Transcriptome Profile During Rabies Virus Infection: Identification of Human CXCL16 as a Potential New Viral Target.

Rabies virus (RABV), the causative agent for rabies disease is still presenting a major public health concern causing approximately 60,000 deaths annually. This neurotropic virus (genus , family ) induces an acute and almost always fatal form of encephalomyelitis in humans. Despite the lethal consequences associated with clinical symptoms of rabies, RABV limits neuro-inflammation without causing major histopathological lesions in humans.

Of mice and men: divergence of gene expression patterns in kidney.

Since the development of methods for homologous gene recombination, mouse models have played a central role in research in renal pathophysiology. However, many published and unpublished results show that mice with genetic changes mimicking human pathogenic mutations do not display the human phenotype. These functional differences may stem from differences in gene expression between mouse and human kidneys.

Tissue compartment analysis for biomarker discovery by gene expression profiling.

Background: Although high throughput technologies for gene profiling are reliable tools, sample/tissue heterogeneity limits their outcomes when applied to identify molecular markers. Indeed, inter-sample differences in cell composition contribute to scatter the data, preventing detection of small but relevant changes in gene expression level. To date, attempts to circumvent this difficulty were based on isolation of the different cell structures constituting biological samples.

A reliable diagnosis of human rabies based on analysis of skin biopsy specimens.

Background: The number of human deaths due to rabies is currently underestimated to be 55,000 deaths per year. Biological diagnostic methods for confirmation of rabies remain limited, because testing on postmortem cerebral samples is the reference method, and in many countries, sampling brain tissue is rarely practiced. There is a need for a reliable method based on a simple collection of nonneural specimens.

Aspirin inhibits human bradykinin B2 receptor ligand binding function.

The bradykinin B2 receptor, a member of the G protein-coupled receptors superfamily, is involved in a variety of physiological functions, including vasodilation, electrolyte transfer in epithelia, mediation of pain, and inflammation. The effect of aspirin on bradykinin binding to cell-surface receptor and on signal transduction were studied in CHO-K1 cells, stably expressing the human B2 receptor. Cell-surface organization of the receptor was assessed by immunoprecipitation and Western blot analysis in CHO-K1 cells expressing N-terminally V5-tagged B2 receptor.
