Protection against HIV-envelope-induced neuronal cell destruction by HIV attachment inhibitors

Protection against HIV-envelope-induced neuronal cell destruction by HIV attachment inhibitors We demonstrate that HIV attachment inhibitors (AIs) prevent HIV envelope-induced destruction of two neuronal cell lines (SH-SY5Y and BE(2)-M17) at low nanomolar concentrations. The fusion inhibitor enfuvirtide and the CCR5 inhibitors UK427,857 and TAK779 do not display protection activity, suggesting the involvement of Env/cell interaction site(s) distinct from the sites involved in the viral entry process. We surmise that by inducing conformation changes in the envelope, AIs likely obstruct novel interactions with a neuronal cell factor(s) required for induction of apoptosis. This antiretroviral class may therefore have the potential to inhibit HIV-induced neuron damage, thereby curtailing the increasing incidence of HIV-associated cognitive impairment. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals
