Laurence U. Buxbaum, M.D., Ph.D.

Laurence U. Buxbaum, M.D., Ph.D. Dr. Buxbaum is interested in the immunology of parasites and studies the initiation and maintenance of cell-mediated immunity (Th1 response) elicited by the protozoan parasite, Leishmania, using a murine model of cutaneous disease. He is examining the role of IL-10 in the suppression of a protective immune response to Leishmania mexicana, which usually causes chronic disease. He has also focused on the detrimental role of antibodies and their receptors in leishmaniasis. Recent work has begun on the role of glycolipids as targets of antibody responses.
