Abstract:

Curcumin improves the learning and memory deficits in rats induced by the gp120 V3 loop. The present study cultured rat hippocampal neurons with 1 nM gp120 V3 loop and 1 μM curcumin for 24 hours. The results showed that curcumin inhibited the gp120 V3 loop-induced mitochondrial membrane potential decrease, reduced the mRNA expression of the pro-apoptotic gene caspase-3, and attenuated hippocampal neuronal injury.

Key words: curcumin, gp120 V3 loop, hippocampal neurons, mitochondrial membrane potential, caspase-3, human immunodeficiency virus-associated neurocognitive function, neural regeneration
