Interleukin IL-1β also known as catabolin, is a member of the interleukin 1 cytokine family. IL1B, the cytokine encoded by the IL1B gene, is an inflammatory response and fever mediator, and contributes to several lymphocyte activities including growth and differentiation of B-cells, proliferation of T-helper Type2 (Th2) clones, and activation of Th17 cells. IL-1β is produced in peripheral blood mononuclear cells, tissue macrophages, and dendritic fine cells in response to immune responses, inflammation, infection, and trauma cells such as cytium. IL1B is required for T-cell activation in some immune responses, and thus could contribute to increased T-cell replication. IL-1β can also act on distant target cells in an endocrine manner to induce systemic immune response. IL-1β can rapidly induce the expression of cytokines such as IL-6 and IL-8 of various cell types. At the same time, IL-1β also induces its own expression, forming a positive feedback loop and amplifying the IL-1 response.
