CURRENT RESEARCH INTERESTS

 

Failure to clear apoptotic cell contributes to autoimmune diseases, such as SLE. However, the cellular and molecular defects caused the failure need to be defined. Mice deficient in MFG-E8 can not clear apoptotic cell in a timely fashion. My main interest is to examine how MFG-E8 deficiency affects both innate and adaptive immunity, including: monocyte/dendritic cell differentiation, cross-presentation of apoptotic cell to T cells and B cell response to apoptotic cell associated antigen.
