TLR8 (Toll-Like Receptor 8) is an endosomal pattern recognition receptor that recognizes single-stranded RNA (ssRNA) and synthetic compounds like imidazoquinolines. TLR8 is structurally and functionally related to TLR7 and is expressed primarily in monocytes and neutrophils. It plays important roles in antiviral immunity and has been implicated in inflammatory and neurodegenerative conditions.
TLR8 is a type I transmembrane protein localized in endosomal compartments:
TLR8 plays important roles in innate immunity:
