Dr. Mailliard's research focuses on the central role played by dendritic cells (DCs) in the induction and regulation of the immune response. In particular, he is interested in the modulation of DC function for the purpose of developing effective cellular based immunotherapies to treat chronic diseases such as cancer and HIV. His work has led to the development of the so-called "alpha-DC1," a type-1 polarized dendritic cell-based vaccine platform currently being explored in clinical trials for the treatment of cancers and HIV. Also of interest to Dr. Mailliard are the non-classical “helper” functions of NK cells and CD8+ T cells (CTLs), and their influence on DC function during infection. Currently, he is exploring the use of DCs as an immunotherapeutic strategy to both drive HIV latency reversal and to prime cytotoxic T cells against HIV-1 infected cells. Dr Mailliard is also the Director of the MS Program of IDM, and the Co-Director of the Pitt HIV Immunology Technologies (HITs) Laboratory that provides immunology laboratory services for the Multicenter AIDS Cohort Study (MACS) and the AIDS Clinical Trials Group (ACTG).
