Figure 7From: Glial TNFα in the spinal cord regulates neuropathic pain induced by HIV gp120 application in rats Peripheral gp120 application increased the expression of TNFα in the DRG. At 2 weeks after gp120 application, a clear immunostaining of TNFα in the DRG was shown (B), but TNFα in the sham group was weak (A). Bar graph showed TNFα expression in the DRG using Western blots (C), p < 0.05 vs sham, n = 3, t test.Back to article page
