Pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α also trigger pathological pain. [1] While IL-1β is released by monocytes and macrophages, it is also present in nociceptive DRG neurons. IL-6 plays a role in neuronal reaction to an injury. TNF-α is a well known proinflammatory cytokine present in neurons and the glia.
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.

IL-1R signalization activates immune response by activation of transcription of IL-1 target genes such as IL-6, IL-8, MCP-1, COX-2, IκBα, IL-1α, IL-1β, MKP-1. Components of signalization pathway of IL-1R which are involved in cellular response to IL-1 also mediate responses to other cytokines (IL-18 and IL-33), Toll-like receptors (TLRs ...
Cao's lab confirmed the kinase's activity as necessarily associated with the IL-1 receptor by immunoprecipitating the IL-1 receptors from different cell types treated with IL-1 and without IL-1. Even cells without over-expressed IL-1 receptors showed kinase activity when exposed to IL-1, and were able to co-precipitate a protein kinase with ...

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]
Interleukin-1 alpha (IL-1 alpha) also known as hematopoietin 1 is a cytokine of the interleukin 1 family that in humans is encoded by the IL1A gene. [5] [6] In general, Interleukin 1 is responsible for the production of inflammation, as well as the promotion of fever and sepsis. IL-1α inhibitors are being developed to interrupt those processes ...
