Summary of research interest:
Our lab is interested in studying B cells mediated immune regulation in autoimmune diseases and cardiovascular diseases. We are particularly interested in a sub-population of B lymphocytes called B1 B cells. Our preliminary study revealed many faces of B1 B cells in health and diseases. On one hand B1 B cells are critical for immune defense and immune regulation through interaction with other immune cells and producing natural antibodies. On the other hand, B1 B cells are potential “troublemakers” in autoimmune diseases because of their auto-reactivity. A better understanding of the balance between the immune-regulation and pathogenicity of B1 B cells are of significant importance in studying inflammatory autoimmune diseases and cardiovascular diseases.
