| Summary |
The protein encoded by this gene is a member of the Toll-like receptor (TLR) family which plays a fundamental role in pathogen recognition and activation of innate immunity. TLRs are highly conserved from Drosophila to humans and share structural and functional similarities. This protein is a cell-surface protein that can form heterodimers with other TLR family members to recognize conserved molecules derived from microorganisms known as pathogen-associated molecular patterns (PAMPs). Activation of TLRs by PAMPs leads to an up-regulation of signaling pathways to modulate the host's inflammatory response. This gene is also thought to promote apoptosis in response to bacterial lipoproteins. This gene has been implicated in the pathogenesis of several autoimmune diseases. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

Induction of TLR4/TLR2 Interaction and Heterodimer Formation by Low Endotoxic Atypical LPS.
IF=5.9
Frontiers in immunology
The Toll-like receptor 4 (TLR4)/myeloid differentiation protein-2 (MD-2) complex is considered the major receptor of the innate immune system to recognize lipopolysaccharides (LPSs). However, some atypical LPSs with different lipid A and core saccharide moiety structures and compositions than the well-studied enterobacterial LPSs can induce a TLR2-dependent response in innate immune cells. , an opportunistic pathogen, presents an atypical LPS. In this study, we found that LPS exhibits a weak inflammatory activity compared to LPS and, more importantly, is a specific TLR4/TLR2 agonist, able to signal through both receptors. Molecular docking analysis of LPS predicts a favorable formation of a TLR2/TLR4/MD-2 heterodimer complex, which was experimentally confirmed by fluorescence resonance energy transfer (FRET) in cells. Interestingly, the core saccharide plays an important role in this interaction. This study reveals for the first time TLR4/TLR2 heterodimerization that is induced by atypical LPS and may help to escape from recognition by the innate immune system.
This KO model may be useful for:
- Investigating TLR2-dependent and -independent signaling pathways in response to atypical LPS.
- Studying TLR2/TLR4 heterodimer formation and functional interactions.
- Evaluating the role of TLR2 in modulating endotoxin-induced immune responses.
- Characterizing ligand specificity and receptor cross-talk in innate immunity.
- Screening for compounds that selectively target TLR2-mediated signaling.
