Over 35 million people are infected currently with the Human Immunodeficiency Virus (HIV), of whom 30-50% will experience Distal Sensory Polyneuropathy (DSP), usually causing paresthesiae and neuropathic pain, particularly in the feet. This presentation is identical to patients with Diabetic DSP. Current regimens for treating neuropathic pain have limited benefits. Thus, a deeper understanding of the mechanisms of HIV-DSP is imperative to permit the rational development of new therapies. Transgenic mice expressing the HIV-1 viral protein R (Vpr) show footpad epidermal denervation and allodynia as observed in HIV-infected patients. We found that exogenous Vpr inhibits axon outgrowth, causes hyperexcitability and increases cytosolic calcium in cultured dorsal root ganglion neurons (DRGN). Exposure of DRGN to nerve growth factor (NGF) or modulating NGF signaling pathways before Vpr treat.. Read More»
