Description | IL-1 beta (IL-1β) is a member of the interleukin 1 family of cytokines. The IL-1 beta cytokine is produced by activated macrophages as a proprotein, which is proteolytically processed to its active form by caspase 1 (CASP1/ICE). This cytokine is an important mediator of the inflammatory response, and is involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis. Human IL-1 beta Recombinant Protein is purified interleukin-1 beta cytokine produced in yeast. |
