GFAP expression in the hippocampus of ICV-administered gp120 rats. (A) Immunohistochemical, (B) immunoblotting (upper panel) and densitometric analysis (lower panel) of GFAP in the hippocampus of ICV-administered gp120 rats are compared to saline-treated animals. A representative blot is shown. Results are expressed as mean ± SEM. For immunoblotting, samples obtained from five different animals were used per group. Asterisk represents a data point significantly different from saline-administered animals (*P <0.05). (GFAP = glial fibrillary acidic protein; ICV = intracerebroventricular; gp120 = glycoprotein120).
