Professor Rudd’s research focuses on signal transduction pathways in T lymphocytes and how these pathways control immune functions. His lab has discovered the CD4 and CD8-p56lck complexes, the initiators of phosphorylation and activation cascade in T lymphocytes. His most recent interest has been in the pathways that control T cell adhesion and lymphocytes in lymph nodes and the mechanisms by which co-receptors such as CD28 and CTLA-4 control immunity. He identified serine / threonine kinase glycogen synthase kinase (GSK-3) as a central regulator of the expression of programmed cell death-1 (PD-1) on T cells and showed the applicability of small inhibitors molecules of GSK-3 in the negative regulation of PD-1 for the clearance of viral infections. His research helps to uncover the signaling events that control the adaptive immune response and help develop therapeutics for the treatment of infection, autoimmunity and cancer.
