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