Research Interests:

Helper T Lymphocyte Biology

Jenkins and his colleagues investigate CD4+ helper T and B cell activation in vivo at a level that can only be achieved by directly tracking antigen-specific cells. Using gene-targeted recipients or antibody blocking approaches, they identify molecules that are critical for in vivo T and B cell signal transduction, proliferation, lymphokine production, survival, and differentiation. The goal is to achieve a basic understanding of these process so that they can be manipulated to improve vaccines and prevent autoimmunity.
