TLR5 (Toll-Like Receptor 5) is a pattern recognition receptor of the innate immune system that recognizes bacterial flagellin. TLR5 is expressed on immune cells and various tissues, where it triggers pro-inflammatory responses upon flagellin recognition. Emerging research suggests TLR5 plays roles in neuroinflammation and neurodegenerative diseases.
TLR5 is a type I transmembrane protein:
TLR5 plays important roles in innate immunity:
