Dr. Jenkins received his Ph.D. in Microbiology and Immunology in 1985 from Northwestern University. He conducted postdoctoral training in the laboratory of Dr. Ronald Schwartz in the Laboratory of Immunology at the National Institutes of Health. He joined the Microbiology Department at the University of Minnesota in 1988, where he conducts research on the biology of CD4+ helper T cells. In 2002 he received the American Association of Immunologists-Huang Foundation Meritorious Career Award and in 2004 was elected to the Academy for Excellence in Health Research.

Research Interests

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.
