Abstract
In the present disclosure, doxycycline-inducible astrocyte-specific HIV Tat transgenic mice (iTat), a surrogate HAND model, were treated with PNU-125096, a positive allosteric modulator of α7 nicotinic acetylcholine receptor (α7 nAChR) and effects on Tat-induced behavioral impairments and neuropathologies were observed. This disclosure shows that PNU-125096 treatment significantly improved locomotor, learning and memory deficits of iTat mice while inhibited glial activation and increased PSD-95 expression in the cortex and hippocampus of iTat mice. α7 nAChR knockout eliminated the protective effects of PNU-125096 on iTat mice. In addition, inhibition of p38 phosphorylation by SB239063, a p38 MAPK-specific inhibitor, exacerbated Tat neurotoxicity in iTat mice. These findings demonstrated for the first time that α7 nAChR activation led to protection against HAND and suggest that α7 nAChR and PNU-125096 hold significant promise for development of therapeutics for HAND.
