IFNAR1 is a type I membrane protein with an extracellular domain containing multiple fibronectin type III repeats, a transmembrane domain, and a cytoplasmic domain. The extracellular domain is responsible for ligand binding, while the cytoplasmic domain interacts with JAK1 to initiate signaling. The receptor undergoes conformational changes upon interferon binding that facilitate complex formation with IFNAR2.
In the CNS, IFNAR1 mediates type I interferon signaling in microglia, astrocytes, and neurons. It plays roles in:
| Disease | Role | Mechanism |
|---|---|---|
| Alzheimer's Disease | Risk factor | Chronic type I IFN signaling promotes neuroinflammation, microglial activation, and synaptic dysfunction |
| Parkinson's Disease | Risk factor | Altered interferon response in dopaminergic neurons |
| Multiple Sclerosis | Modifier | IFN-β therapy acts through IFNAR signaling |
| Aicardi-Goutières Syndrome | Causative | Dysregulated type I interferon signaling |
