Regulation of innate and adaptive immune responses by the related cytokines IL-12, IL-23, and IL-27

Abstract excerpt

The functional characterization and subsequent purification of T cell growth factor/interleukin (IL)-2 in the early 1980s established this secreted protein as a key mediator of immune cell activation and provided the prototype that enabled the discovery of numerous cytokines over the ensuing two decades. While soluble immunoregulatory factors were initially identified functionally as biological activities present...
