My research focuses on the flow cytometric characterization of T cells induced by candidate T cell vaccines tested within the HIV Vaccine Trials Network (HVTN). We have developed assays that examine multiple T cell markers and functions simultaneously. An ultimate goal of this research is to identify the characteristic features of effective immune responses. This goal may not be achievable until larger phase II and III efficacy trials are performed, but in the interim, we use these assays to compare T cells induced by different vaccine regimens. Recent studies in our laboratory related to the failure of the vaccine tested in the Step trial have resulted in a broader examination of the potential impact of vaccination on the immune system. We are examining T cells that are specific for the vaccine vector. We are also developing methods to identify regulatory or suppressive T cells that can potentially be induced by vaccination.
