HIV-1R Viral Protein R and Memory Impairment

Using Synpatophysin as Marker for Synaptic LossOur Neuron-Glial Markers continue to shine in challenging applications. Here researchers examined whether infusion of the Vpr-expressing astrocytes affected synaptophysin expression in the hippocampus. The authors of the study, using Neuromics' Mouse Monoclonal Synaptophysin Antibody,  found a significant reduction in synaptophysin staining in CA3: Lilith Torres and Richard J Noel. Astrocytic expression of HIV-1 viral protein R in the hippocampus causes chromatolysis, synaptic loss and memory impairment. Journal of Neuroinflammation 2014, 11:53 doi:10.1186/1742-2094-11-53.Images: Astrocytic HIV-1 viral protein R (Vpr) expression decreased synaptophysin immunoreactivity (A) Representative light photomicrograph showing the distribution of synaptophysin immunoreactivity in the rat hippocampal CA3 formation. Green fluorescent protein (GFP) right side. Vpr shows both left and right. Magnification 100×. (B) Densitometric analysis revealed significantly decreased mean value for the Vpr group compare to control.Protocol: To examine changes in synaptophysin between control and HIV-1 Vpr exposed rats, tissue sections from each group were processed for immunocytochemistry. The samples were cut at 4 μm thickness with a microtome (Microm HM340, Microm International) and fixed to positively charged microscope slides. Fixed tissues were deparaffinized in xylene substitute for 30 minutes, rehydrated through graded alcohols and neutralized...
