Anti-TLR7 Antibody is a humanized monoclonal antibody targeting Toll-like receptor 7 (TLR7). TLR7 is a pattern recognition receptor primarily located on endosomal membranes that recognizes single-stranded RNA (ssRNA), playing a pivotal role in antiviral immune responses and autoimmune diseases such as Systemic Lupus Erythematosus (SLE). This antibody specifically binds to TLR7, blocking its activation by ligands (e.g., viral RNA or synthetic agonists) and subsequently inhibiting the downstream MyD88-dependent signaling pathway and the production of Type I interferons (IFN-α/β). By modulating TLR7 signaling, Anti-TLR7 Antibody serves as a valuable tool for investigating viral infection mechanisms and therapeutic strategies for autoimmune disorders.
