The Taylor laboratory studies new approaches for cancer treatment based on the interaction of cancer cells with the complement system. In the presence of serum and normal human IgM and/or specific monoclonal antibodies, large amounts of the complement activation product, C3bi, covalently bind to cancer cells. The lab uses monoclonal antibodies specific for cell-associated C3bi to facilitate tumor cell targeting and killing in their studies.
