About Research

Our research focuses on various aspects of T cell function:

Immune Regulation:

  • Regulatory T cells (Tregs):
    Identification of novel Treg molecules and their function; mechanism of Treg function; IL-35 signaling and mechanism of action; regulation of Treg stability via the Nrp1 pathway; biology of IL-35 and Nrp1 in cancer, mucosal immunity (particularly asthma and intestinal pathogens) and autoimmunity (particularly type 1 diabetes).
  • Inhibitory Molecules:
    LAG3 signaling and mechanism of action; synergy between LAG3 and other inhibitory receptors, particularly PD1; immune modulation by LAG3 and PD1 in tumors, mucosal immunity (particularly asthma and intestinal pathogens) and autoimmunity (particularly type 1 diabetes).
  • Type 1 diabetes:
    In additional to the topics above: importance of TCR specificity and affinity in the diabetogenic or regulatory potential of T cells; mechanisms that regulate T cell islet entry and diabetogenicity.

T cell receptor (TCR):CD3 complex: Molecular initiation and control of TCR signal transduction; role of CD3 in T cell development and function.
