Il1B Gene Interleukin 1 Beta is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
This page provides comprehensive information about IL1B Gene, including its structure, normal function in the nervous system, and its role in neurodegenerative diseases.
The IL1B gene encodes interleukin-1 beta (IL-1β), a pro-inflammatory cytokine member of the interleukin-1 family. IL-1β is a key mediator of the inflammatory response and plays a crucial role in the innate immune system. In the central nervous system, IL-1β is produced by microglia, astrocytes, and neurons in response to injury, infection, or disease-associated molecular patterns (DAMPs).
IL-1β binds to the interleukin-1 receptor type I (IL-1R1), forming a complex that activates the MyD88-dependent signaling pathway, leading to activation of NF-κB and MAP kinases. This results in the expression of additional inflammatory mediators, chemokines, and adhesion molecules.
IL-1β is heavily implicated in Alzheimer's disease pathogenesis:
IL1B is expressed in various brain regions with notable expression in:
