IL-1R8 Ativadores

Interleukin 1 Receptor 8 (IL-1R8), also known as Single Ig IL-1-Related Receptor (SIGIRR) or TIR8, is a protein that in humans is encoded by the IL1R8 gene. As part of the interleukin-1 receptor family, IL-1R8 plays a critical role in modulating immune response and inflammation.Unlike other members of the family, IL-1R8 does not actively participate in signal transduction for inflammatory responses. Instead, it acts as a "check" or negative regulator on the immune system. It does this by interfering with the signaling pathways of other, pro-inflammatory members of the interleukin-1 receptor family and Toll-like receptors. By blocking these pathways, IL-1R8 helps to inhibit excessive or chronic inflammation, which can lead to tissue damage and various diseases.

IL-1R8 is expressed in a variety of tissues, including immune cells and epithelial cells, reflecting its broad role in immune regulation. Dysregulation or mutations of IL-1R8 can contribute to an overactive immune response, potentially leading to autoimmune diseases or chronic inflammatory conditions. Conversely, it might also be implicated in immune evasion strategies by tumors.Research has shown that IL-1R8 is a potent modulator of immune response in conditions like sepsis, lung inflammation, and colitis, and it has been suggested as a potential target for these and other inflammatory diseases.
