Research Interest

Regulation of antigen processing and presentation

The development of nano-vaccine for the treatment of chronic infectious diseases regulation of balanced adaptive immune responses and immune tolerance.

1. Quality control of MHC I antigen presentation: The assembly of MHC I and antigenic peptides is regulated by different molecules in the endoplasmic reticulum (ER) of antigen presenting cells. Previous findings indicated that tapasin (TAP-A) has unique function in regulation of MHC I – peptide assembly. We are currently looking into the potential function of tapasin in selection of peptide repertoires for MHC I assembly.

2. Nano-vaccine: Based on our studies in antigen presentation in the ER membrane, we have developed a nano-vaccine delivery system by using MHC – antigen and cytokine engineered ER membrane particles. We found that the delivery of both antigen and mitogenic cytokines directly to antigen specific T cells from HBV chronically infected patients can effectively recall their anti-viral immune responses. We are currently developing HBV therapeutic vaccine for clinical trials.

3. Intrinsic regulation of B and T cell function: B and T cells are major effector lymphocytes in response to pathogen invasion. However, dysregulation of B and T cells can result in inflammatory autoimmunity or immune tolerance to pathogens. In addition to the Treg cells, B and T cells are intrinsically regulated in response to antigen and microenvironments. We are studying the mechanisms of these regulations.

4. Role of early growth response genes (Egr) in the development and function of B and T cells. Egr molecules have been found to control the development and function of B and T cells. We have developed transgenic and knockout models and demonstrated their functions in the control of immune responses and inflammatory autoimmune diseases. We are investigating the molecular mechanisms of Egr function.

All these research topics have implications in autoimmune diseases, microbial and tumor immunity as well as vaccine development.
