Figure 3From: Glial TNFα in the spinal cord regulates neuropathic pain induced by HIV gp120 application in rats The expression of spinal GFAP, Iba1, and TNFα in the gp120 application model. Two weeks after gp120 application, the left L4/5 spinal dorsal horns were harvested under anesthesia, and protein expression of spinal GFAP, Iba1, and TNFα was tested using Western blots. Perineural gp120 application significantly induced the upregulation of GFAP, Iba1, and TNFα in the spinal cord level. *p < 0.05 vs sham, ** p < 0.01 vs sham, t test, n = 3-4.Back to article page
