Interleukin-1 beta (IL-1 beta, IL-1β or IL-1b) was originally called IL-1 beta endogenous pyrogen since it was able to induce fever and contributed to the wasting of muscles (PIF or proteolysis inducing factor). Low levels have been reported in normal serum and IL-1 inhibitors that vary only in their degree of glycosylation have been described to bind to the IL-1 receptor.
