Function
TLR13 (Toll-like receptor 13) is a component of both innate and adaptive immunity. It recognizes and binds to 23S rRNA from bacteria. TLRs play a crucial role in regulating the host's immune response against pathogens by recognizing molecular patterns specific to microorganisms. TLR13 operates through the MYD88 and TRAF6 pathways, leading to NF-κB activation, cytokine secretion, and the subsequent inflammatory response. TLR13 specifically binds to the 5'-CGGAAAGACC-3' sequence on bacterial 23S rRNA, a sequence also targeted by MLS group antibiotics (including erythromycin). There is evidence suggesting TLR13 may also recognize vesicular stomatitis virus; however, further research is needed to confirm this observation.
