The intent of the Creative and Novel Ideas in HIV Research (CNIHR) program is to attract both international and U.S.-based early stage investigators from outside the field of HIV research to help address key scientific questions in HIV research, including emerging issues of long-term survival with HIV infection, prevention of HIV transmission and research towards a cure.

A Super-agonistic antibody to human IL-21 to boost immunity for HIV cure
A Super-agonistic antibody to human IL-21 to boost immunity for HIV cure
Abstract
We have identified a super-agonist monoclonal antibody (mAb) to human IL-21 (hIL-21) by screening homemade libraries. The mAb (clone 2P2) enhances the hIL-21 bioactivity at a level ~10 fold in vitro. The anti-hIL-21 super-agonist mAb represents a novel class of immunostimulating therapeutics to boost IL-21-mediated immune enhancement to eliminate activated latently infected cells for HIV cure. We hypothesize: 1. The super-agonist mAb 2P2 boosts hIL-21 bioactivity to enhance the cytotoxicity of CD8+ T cells and NK cells to eliminate activated latently infected CD4+ T cells. 2.

Targeting Antiapoptotic Signaling for Eradication of HIV Latent Reservoir
Targeting Antiapoptotic Signaling for Eradication of HIV Latent Reservoir
Abstract
Human immunodeficiency virus (HIV) infection creates a long-lived latent reservoir that is maintained during antiretroviral therapy (ART). With a half-life of approximately ~44 months, these latently-infected CD4 T cells threaten recrudescence even after prolonged treatment and are a major impediment to the eradication of virus reservoirs. Our long-term goals are to discover the mechanisms responsible for conveying the very long half-life of latent CD4 T cells and develop strategies to shorten the half-life to allow their elimination during a relevant time interval.
