The Sette lab’s previous large scale epitope identification efforts (supported by HHS contracts) have led to a deeper understanding of the role of T cells and HLA variants in the development of (or protection from) DENV disease. Current efforts (supported in part by a consortium grant led by Eva Harris at UC Berkeley) addresses questions including whether infection with different serotypes is associated with distinct types of T cell responses, whether any HLA alleles are associated with pathogenesis or protection, and whether vaccination with a formulation in clinical trials is associated with T cell responses similar to those following infection that might serve as correlates of protection.
