"IFN-[gamma], which is produced primarily by T-helper (Th) cells of the Th1 and Th0 subtypes, CD8+ T cells, and natural killer cells, is the main immunoregulator. IFN-[gamma] directs differentiation of T cells to a Th1 phenotype and induces display of major histocompatibility complex class I and II molecules on different cell types in cell-mediated responses.
