Clark

Dr. Clark’s laboratory is interested in the cell biology of the T lymphocyte as at relates to autoimmune diseases. The immune response in autoimmune diseases such as Multiple Sclerosis and Rheumatoid Arthritis, as well as animal models for these diseases are studied at the level of the T cell. T cell gene usage, T cell function and activation, and T cell migration and homing are studied using T cell cloning and molecular biological approaches. The understanding of basic T cell function as it relates to autoimmune mediated pathology is the overall goal of this laboratory.
