Molecular and Genetic Determinants of iNKT Cell Function
Dr. Boyson received his PhD from the University of Wisconsin-Madison in 1997. From 1998 to 2003, he conducted his postdoctoral research at Harvard University in the Department of Molecular and Cellular Biology in the laboratory of Dr. Jack L. Strominger. Dr. Boyson joined the CMB program in 2003.
Semi-invariant NKT cells comprise an unusual, highly conserved, lymphocyte subset that has been implicated in tolerance induction, tumor immunology, autoimmunity, and infectious disease. Unlike most T cells which recognize peptide bound by class I MHC molecules, iNKT cells bind glycolipids bound by the class I MHC-like molecule CD1d. Upon activation, NKT cells produce both Th1 (e.g., IFN-gamma and TNF-alpha) as well as Th2 (e.g., IL-4, IL-10, and IL-13) cytokines. Accordingly, they have been observed to play roles in both pro-inflammatory as well as tolerogenic immune responses. Rapid production by NKT cells of a wide variety of cytokines elicits the downstream activation of both innate and adaptive immune cell subsets such as NK cells, macrophages, dendritic cells, and B cells. These characteristics suggest that NKT cells could play a pivotal early role in shaping developing immune responses.
Research in the lab focuses on the investigation of the factors that govern iNKT cell activation and function. We have demonstrated strain-dependent susceptibility to NKT-mediated diseases such as asthma and pregnancy loss is significantly correlated with strain-dependent variability in iNKT cell number and function. Therefore, we are using genetic, molecular, and biochemical techniques to identify factors that modulate iNKT cell function in vivo, and to determine how they affect downstream immune responses.
