Type I interferons (IFN) are important regulators of both innate and acquired immunity. We have used an in vitro system of human CD4+. T cell differentiation to determine how IFN-β influences development of T helper (Th) subsets and homing receptor expression. IFN-β promoted differentiation of CD4+. T cells that produce low levels of both IFN-γ and lymphotoxin compared to interleukin (IL)-12-derived Th1 CD4+ T cells. IFN-β inhibited production of Th2 cytokines (IL-5 and IL-13) and augmented IL-12-mediated IL-10 secretion. In addition. IFN-β significantly enhanced L-selectin expression on CD4+ T cells and synergized with IL-12 to induce expression of cutaneous lymphocyte-associated antigen (CLA). This Th1 L-selectin+, CLA+ phenotype is characteristic of T cells found in normal human skin and suggests a role for type T IFN in the regulation of Th subset differentiation and tissue-specific homing receptors.
