Chief, Laboratory of ImmunologyChief, Cytokine Biology Unit, LINational Institutes of Health Distinguished Investigator
The Cytokine Biology Unit studies the mechanisms of action and biologic functions of cytokines, emphasizing the role of the type II cytokines (IL-4, IL-13, and IL-5) as well as members of the IL-1 cytokine family. The unit also carries out research on the mechanisms through which naïve CD4 T cells differentiate into the various Th phenotypes, most notably into the molecular mechanisms underlying Th2 commitment. It has recently emphasized innate functions of lymphocytes, both those of conventional Th cells, most notably the capacity of Th2 cells to produce IL-13 and IL-5 in response to cytokine signals, and the consequent protective functions of these cells. An important research effort now centers on a newly described population of innate lymphoid cells, Kbri cells, that act as progenitors of ILC2 and ILC3 cells and respond to inflammatory/infectious stimulants. It has developed new strategies to enhance immune responses with the goal of increasing the protective capacity of weak vaccines.

Flexibility and plasticity among CD4 Th cells. The classical view that naïve CD4 T cells differentiate into cells of distinct lineage that are largely not interconvertible has been challenged by recent results showing that these cells can adopt new phenotypes. The degree and physiologic significance of such plasticity remain to be determined. From O’Shea JJ, Paul WE. Mechanisms underlying lineage commitment and plasticity of helper CD4+ T cells.
