IL-1 Signaling Pathway (Homo sapiens)

The interleukin 1 family of cytokines includes interleukin-1 alpha (IL1A), beta (IL1B) and the IL-1 receptor antagonist (IL1RN). These bind to the IL-1 receptor (IL1R1) as well as its decoy receptor, IL1R2. Upon binding to the ligands, interleukin-1 alpha or beta, IL1R1 interacts with IL-1 receptor accessory protein (IL1RAP) to activate the MAPK/JNK signaling modules. The MAPK pathway leads to activation of NFkB complex. As both IL-1 and TNF alpha stimulate the MAPK signaling module and activate NFkB, they are synergistic and complement each other's activity.

NetPath 13: IL-1 Signaling Pathway

NetPath (http://www.netpath.org) is a collaborative project between PandeyLab at Johns Hopkins University (http://pandeylab.igm.jhmi.edu) and the Institute of Bioinformatics (http://www.ibioinformatics.org). If you use this pathway, you must cite the NetPath website until the pathway is published.
