Interleukin-1 beta (IL-1β) also known as leukocytic pyrogen, leukocytic endogenous mediator, mononuclear cell factor, lymphocyte activating factor and other names, is a cytokine protein that in humans is encoded by the IL1B gene.
IL-1ra is an important regulator of IL-1-induced expression and physiological responses elicited by IL-1. IL-1ra functions as a competitive inhibitor of IL-1 receptor in vivo and in vitro. It counteracts the effects of both IL-1α and IL-1β. Upon binding of IL-1ra, the IL-1 receptor does not transmit a signal to the cell.
The receptors can both bind all three forms of IL-1 (IL-1 alpha, IL-1 beta and IL-1 receptor antagonist). The crystal structures of IL1A and IL1B [ 9 ] have been solved, showing them to share the same 12-stranded beta-sheet structure as both the heparin binding growth factors and the Kunitz-type soybean trypsin inhibitors.

The inflammasome was discovered by the team of Jürg Tschopp, at the University of Lausanne, in 2002. [17] [18] In 2002, it was first reported by Martinon et al. [17] that NLRP1 (NLR family PYD-containing 1) could assemble and oligomerize into a structure in vitro, which activated the caspase-1 cascade, thereby leading to the production of pro-inflammatory cytokines, including IL-1β and IL-18.
Caspase-1 Zymogen. Caspase-1/Interleukin-1 converting enzyme (ICE) is an evolutionarily conserved enzyme that proteolytically cleaves other proteins, such as the precursors of the inflammatory cytokines interleukin 1β and interleukin 18 as well as the pyroptosis inducer Gasdermin D, into active mature peptides.
Interleukin-1 receptor (IL-1R) is a cytokine receptor which binds interleukin 1. [1] Two forms of the receptor exist. The type I receptor is primarily responsible for transmitting the inflammatory effects of interleukin-1 (IL-1) while type II receptors may act as a suppressor of IL-1 activity by competing for IL-1 binding. [1]
They also induce the synthesis and release of other pro-inflammatory cytokines such as interleukin 1 (IL-1), IL-6 and TNF-α from fibroblasts and macrophages. The genes for CCL3 and CCL4 are both located on human chromosome 17 [ 9 ] and on murine chromosome 11.
IL-1RAcP is a second receptor subunit of IL-1RI. By forming a receptor heterodimer with IL-1RI facilitates signalization due to oligomerization of TIR domains of these proteins. [14] IL-1RAcP does not bind IL-1 but it binds IL-1RI through its Ig-like domains 1 and 2 and is necessary for IL-1R1 signalling.
