The Immunobiology Section studies host resistance and immune regulation in parasitic and other infections of global importance. The ultimate goal of this work is immunologic disease intervention in the form of vaccination or immunotherapy. At the same time, our research on the host response to infection has provided insights into the effector functions and regulatory mechanisms used by the vertebrate immune system and in the role of innate pathogen recognition in these processes. Much of the work of the section is focused on the immunologic analysis in murine models of diseases induced by parasitic and bacterial agents (e.g., Toxoplasma gondii, Mycobacterium spp.), although the group is also engaged in several major clinical collaborations. The lab also has a major interest in the regulation of Th1-dependent immunopathology in T. gondii and mycobacterial infections as well as tuberculosis-HIV co-infection.
Dr. Sher received his Ph.D. from the University of California, San Diego, and did his postdoctoral training in the Division of Parasitology at the National Institute for Medical Research in Mill Hill, London. In 1980, after several years as a research associate and then assistant professor in the department of pathology at Harvard Medical School, he joined NIAID as a section chief in the Laboratory of Parasitic Diseases. Sher became chief of LPD in 2003 and was promoted to NIH Distinguished Investigator in 2011.
