Human IL-1β Analyte Overview
Also known as Interleukin 1 beta, IL1β, leukocytic pyrogen, leukocytic endogenous mediator, mononuclear cell factor, lymphocyte activating factor, pre-interleukin 1 beta, catabolin
Interleukin 1 beta (IL-1β) is a cytokine involved in pro-inflammatory responses. It is produced by activated macrophages, natural killer cells, monocytes, and neutrophils in response to wounds, infections, or microbial endotoxins and is processed to its active state by caspase 1. It mediates inflammatory responses and plays a role in cell proliferation, apoptosis, and differentiation. IL-1β inflammation within the central nervous system is known to result in pain and hypersensitivity. High levels of IL-1β are associated with autoinflammatory diseases, particularly the group of rare heterozygous dominant diseases known as cryopyrin-associated periodic syndromes, that often affect the skin, joints, eyes, and nervous system. Inhibition of IL-1β treats these diseases and eases symptoms in common conditions such as type 2 diabetes, cardiac failure, gout, and rheumatoid arthritis. Dysregulated IL-1β is associated with tumor formation in a wide variety of cancers.
