Interleukin-1 is a pro-inflammatory cytokine with multiple biological effects. The IL-1 gene family encodes three proteins: IL-1α, IL1-beta and their naturally occurring inhibitor IL-1RN. Interleukin 1 beta (IL-1 beta), mainly produced by blood monocytes and tissue macrophages, has been implicated in mediating both acute and chronic inflammation. IL-1 beta is known to be involved in a variety of cellular activities, including cell proliferation, differentiation and apoptosis. IL-1 beta is emerging as a key mediator of carcinogenesis that characterizes host-environment interactions.
