Research Overview:

The laboratory of L. Teyton is trying to elucidate the molecular mechanisms by which the ligation of the T cell receptor to its ligand, an MHC-peptide complex, activates T cells. Similar studies are carried out on TCR/pMHC pairs involved in autoimmune diseases with two goals. First, identify self-peptides involved in autoimmunity. Secondly, measure the affinity of self MHC-self pMHC complexes and determine if pathogenic T cells arise from escaping negative selection or breakage of peripheral tolerance. The corollary question is to determine if autoimmunity is a deviance of a normal immune response or the innate property of a T cell response against a self-antigen. The answers to these questions will be determinant in choosing new therapeutic strategies.
