Most diseases accompanied with inflammation, autoimmunity, and infection are associated with changes in cytokine, chemokine, and growth factor production. We investigate roles of these mediators related to the processes of inflammation and carcinogenesis.
In particular, we study the biology of cytokines and mediators that are associated with Th1-like inflammation with focus on IFNγ, IL-22, the IL-1 family of cytokines, and nitric oxide.
