TLR5

The Toll-like receptor 5 (TLR5) is a protein encoded by the TLR5 gene, which is a member of the Toll-like receptor (TLR) family. TLR5 is commonly known as MELIOS, SLE1, SLEB1, TIL3, and toll like receptor 5. It plays a crucial role in innate immunity by recognizing bacterial flagellin, a principal component of bacterial flagella. Upon activation, TLR5 mobilizes the nuclear factor NF-kappaB, leading to the activation of inflammatory-related target genes. TLR5 signaling is involved in various immune responses, including the regulation of intestinal mucosal immunity and the defense against infectious diseases. Mutations in the TLR5 gene have been associated with susceptibility to systemic lupus erythematosus and Legionnaire disease. Additionally, TLR5 is being investigated as a potential target for drug development in various inflammatory and autoimmune diseases.
