Figure 2From: Glial TNFα in the spinal cord regulates neuropathic pain induced by HIV gp120 application in rats The expression of spinal TNFα mRNA in the perineural gp120 application model using quantitative real time RT-PCR. Two weeks after gp120 application, left L4/5 spinal dorsal horns were harvested under anesthesia and mRNA expression was examined using quantitative real time RT-PCR. Perineural gp120 application significantly upregulated spinal mRNA of TNFα. * p < 0.05 vs sham, n = 3-5, t test.Back to article page
