Chemically modified drug shows promise for HIV treatment, elimination

Research Interests

My major focus is to understand the drug-drug interactions on molecular pathways for HIV therapeutics and elimination. Thirty-seven years after the discovery that HIV is the causative agent of AIDS, there is still the problem of drug adherence, drug dosing and appearance of drug resistant strains, and unfruitful targeting of drugs to the latent reservoirs in the patients. There are only two documented cases of HIV-1 functional cure till date. The subsequent success was stalled because of 1) limited therapeutic access to viral reservoirs, 2) the known rapid spread of viral infection, 3) much higher numbers of viral susceptible cells in HIV-1 target tissues and 4) an inability to completely eliminate integrated proviral DNA. Viral rebound is uniformly seen after cessation of antiretroviral therapy (ART). To address each of these limitations, I am working with a medicinal chemistry team to improve drug penetrance across cell and tissue barriers and to improve control over ongoing viral infection. We reasoned that, under conditions of optimal viral restriction, deployment of CRISPR/Cas9 proviral DNA excision strategies targeting specific host genes responsible for viral entry and multiple regions of HIV-1 genome would facilitate elimination of HIV-1 from the host genome. This will be validated using multiple highly sensitive molecular detection in vitro and in vivo assays.
