Safety and efficacy of G2-S16 dendrimer as microbicide in healthy human vaginal tissue explants

J Nanobiotechnology. 2022 Mar 21;20(1):151. doi: 10.1186/s12951-022-01350-8.

Abstract

Background: The absence of an effective treatment and vaccine in HIV-1 pandemic place preventive strategies such as safety and effective microbicide development as a central therapeutic approach to control HIV-1 pandemic nowadays.

Results: Studies of cytotoxicity, immune population status, inflammation or tissue damage and mainly prophylactic inhibition of HIV-1 infection in vaginal human explants demonstrate the biosafety and effectivity of G2-S16 dendrimer. Human explants treated with G2-S16 dendrimer or treated and HIV-1 infected do not presented signs of irritation, inflammation, immune activation or T cell populations deregulation.

Conclusions: Herein we conclude that G2-S16 dendrimer has demonstrated sufficient efficacy, biosafety, effectivity and behavior in the closest to the real-life condition model represented by the human healthy donor vaginal tissue explants, to raise G2-S16 dendrimer as a promising candidate to clinical trials to develop an effective microbicide against HIV-1 infection.
