Interferon α/β receptor binds interferon-α and interferon-β. It is a heterodimer with subunits INFAR1 and INFAR2[1]. For more details see IFNAR and Multiple sclerosis. Interferon γ receptor binds interferon-γ and is a heterodimer with subunits INFGR1 and INFGR2[2]. Interferon δ receptor binds interferon-δ[3]. Relevance Lack of neuronal interferon α/β receptor causes Lewy Body and Parkinson-like dementia in mice[4]. Interferon α/β receptor deficiency has a role in the pathogenesis of lupus[5]. Disease Mutations of interferon γ receptor confer susceptibility to infections caused by mycobacteria[6].
