Proteomics analysis of human brain tissue infected by street rabies virus.
In order to extend the knowledge of rabies pathogenesis, a two-dimensional electrophoresis/mass spectrometry based postmortem comparative proteomics analysis was carried out on human brain samples. Alteration in expression profile of several proteins was detected. Proteins related to cytoskeleton, metabolism, proteasome and immune regulatory systems showed the most changes in expression levels. Among these groups, the cytoskeleton related proteins (dynein light chain, β-centractin, tubulin alpha-1C chain and destrin) and metabolism associated proteins (fatty acid-binding protein, macrophage migration inhibitory factor, glutamine synthetase and alpha enolase) were the main altered proteins. These alterations may be considered as an evidence of disturbances in neuronal key processes including axonal transport, synaptic activity, signaling and metabolic pathways in rabies virus infected human brain.
