Inhibition of p53 transcriptional activity reduces gp120 neuro-toxicity. The small molecule p53 inhibitor, pifithrin-α (PFT), reduces gp120-induced neuronal death (*P < 0.001 vs. gp120) (A). PFT pretreatment (100 nM) also reduces gp120-induced Apaf-1 up-regulation in neurons as determined by Western blot (B).
