HIV-1 Tat inhibits neprilysin and elevates amyloid β

Abstract

We have shown that Tat, which is found in the brains of patients with HIV-1 infection, inhibits the Abeta-degrading enzyme, NEP. Abeta staining was significantly increased in human brain sections from individuals with HIV-1 infection compared to controls. These results have important implications for individuals living and aging with HIV-1 infection.
