Anti-hTLR2-IgA is a chimeric monoclonal antibody specific for human Toll-like receptor 2 (TLR2, CD282). It was generated by combining the constant domains of the human IgA molecule with murine variable regions. This antibody has been selected for its ability to efficiently neutralize the biological activity of TLR2. The neutralizing activity of this IgA antibody was determined using HEK-Blue™ TLR2 Cells. It was found to be significantly higher than the neutralizing activity of the corresponding IgG isotype.

Description

Toll-Like receptors (TLRs) play a critical role in early innate immunity toinvading pathogens by sensing microorganisms. These evolutionary conserved receptors recognize highly conserved structural motifs only expressed by microbial pathogens, called pathogen-associated microbial patterns (PAMPs). Stimulation of TLRs by PAMPs initiates a signaling cascade leading to the secretion of proinflammatory cytokines following NF-κB activation. To date ten human and twelve murine TLRs have been characterized, TLR1 to TLR10 in humans, and TLR1 to TLR9, TLR11, TLR12 and TLR13 in mice, the homolog of TLR10 being a pseudogene.

TLR2 is involved in the recognition of a wide array of microbial molecules. TLR2 recognizes lipoteichoic acid and lipoprotein from gram- positive bacteria, lipoarabinomannan from mycobacteria, and zymosan from yeast cell wall. Moreover, TLR2 participates in the recognition of some types of LPS. TLR2 is known to heterodimerize with other TLRs, a property believed to extend the range of microbial molecules that TLR2 can recognize. TLR2 cooperates with TLR6 in response to diacylated mycoplasmal lipopeptide [1], and associates with TLR1 to recognize triacylated lipopetides [2]. Furthermore, pathogen recognition by TLR2 is strongly enhanced by CD14 [3].
