Anti-TLR5 Antibodies

Antibodies against human and murine TLR5

InvivoGen provides monoclonal antibodies targeting Toll-like receptor 5 (TLR5). These antibodies have been selected for their ability to efficiently neutralize the biological activity of either human or murine TLR5.

TLR5 recognizes flagellin from Gram-positive and Gram-negative bacteria. Activation of the receptor stimulates the production of proinflammatory cytokines, such as TNF-α, through signaling via the adaptor protein MyD88 [1-3]. TLR5 can generate a pro-inflammatory signal as a homodimer suggesting that it might be the only TLR participating in flagellin recognition [3]. However, TLR5 may require the presence of a co-receptor or adaptor molecule for efficient ligand recognition and/or signaling [4].
