T cell antigen recognition
My research centers on how antigen recognition by T cells determines cell phenotype, fate, and outcome of the adaptive immune response. Understanding the mechanisms driving T cell activation provides novel insight into the basis of autoimmune disease and effective response to infections.
Through the use of our novel and sensitive Micropipette assay we are able to determine single bond T Cell Receptor (TCR) affinity for peptide restricted by MHC (pMHC) in T cell subset populations. Our Biomembrane Force Probe is able to analyze TCR:pMHC bond lifetimes under force. Together, Micropipette and BFP analysis of cells provide a clearer picture of T cell interactions with antigens associated with self and pathogens.
