Interleukin-1 receptor type 1 (IL-1R1) is the primary receptor for IL-1α and IL-1β, mediating pro-inflammatory signaling in the brain.
IL-1R1 is a transmembrane receptor of the IL-1 receptor family, consisting of:

Signaling Pathway:
Decoy Receptor:
IL-1R2 acts as a decoy receptor:
Alzheimer's Disease:
Parkinson's Disease:
ALS:
Stroke/TBI:
IL-1R1 expression in brain:
Neurons: High expression, particularly in hippocampus
Astrocytes: Moderate to high expression
Microglia: High expression, increases with activation
Oligodendrocytes: Low expression
Peripheral:
IL-1R1 signaling triggers the NF-κB transcription factor pathway, which plays a critical role in inflammatory gene expression. Upon IL-1 binding, MyD88 recruits IRAK kinases, leading to TRAF6 ubiquitination and IKK complex activation. This cascade results in IκB degradation and NF-κB nuclear translocation, driving expression of pro-inflammatory cytokines, adhesion molecules, and acute phase proteins.
IL-1R1 also activates mitogen-activated protein kinase (MAPK) pathways including ERK, JNK, and p38. These kinases regulate diverse cellular processes including cell proliferation, differentiation, and stress responses. In neurons, MAPK activation contributes to synaptic plasticity but chronic activation can lead to excitotoxicity.
IL-1R1 signaling intersects with multiple other receptor systems:
The study of Il1R1 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
