TLR7 (Toll-Like Receptor 7) is an endosomal pattern recognition receptor that recognizes single-stranded RNA (ssRNA) from viruses and synthetic compounds like imidazoquinolines. TLR7 is primarily expressed in plasmacytoid dendritic cells (pDCs) and other immune cells, where it plays critical roles in antiviral immunity and has been implicated in autoimmune and neurodegenerative conditions.
TLR7 is a type I transmembrane protein localized in endosomal compartments:
TLR7 plays critical roles in antiviral immunity:
