These results indicate that NaHS could significantly ameliorate Aβ1-40-induced spatial learning and memory impairment, apoptosis, and neuroinflammation at least in part via the inhibition of p38 MAPK and p65 NF-κB activity, suggesting that administration of NaHS could provide a therapeutic approach for AD. The gene discussed is NFKB1; the disease is Alzheimer disease.
