Personal Statement

Dr. Mellors is a global leader in the HIV-AIDS research field. His laboratory and translational research programs are at the forefront of efforts to prevent, treat and cure HIV-1 infection. His laboratory has recently shown that most of the reservoir of infectious HIV-1 that persists despite antiretroviral therapy is in clonally-expanded CD4+T-cells. Intense efforts are being directed toward identifying the sites of integration of intact (replication-competent) proviruses in the human genome. In addition, many of the newest immunotherapeutic strategies to cure HIV-1 infection are being tested in his laboratory and through Phase I/II human clinical trials. Examples of such strategies include latency reversing agents (histone deacetylase inhibitors, Toll-like receptor agonists), broadly neutralizing monoclonal antibodies (VRC01 and others), and therapeutic vaccines including dendritic cell-based and viral vectors.

 

Dr. Mellors’ prior work established the critical relationship between plasma viremia (HIV-1 RNA) and HIV disease progression to AIDS and death. This finding led to the universal use of plasma HIV-1 RNA to estimate prognosis in HIV-1 infection and the optimal time to initiate antiretroviral therapy (ART). His work also contributed to the development and testing of the first antiretroviral combinations that produced sustained suppression of HIV and recovery of CD4+ T-cells that launched the current era of highly-effective combination ART.

 

The Mellors laboratory is well balanced and interactive, consisting of graduate and medical students, research specialists, post-doctoral fellows, and junior faculty. Dr. Mellors has mentored many doctoral and medical students who have authored multiple papers and developed successful research careers.
