TLR4-DN (ΔTIR) : Dominant Negative TIR-less TLR4 gene

 

TLR4 is the receptor for Gram- lipopolysaccharide (LPS). The TLR4 gene was shown to be mutated in C3H/HeJ and C57BL/10ScCr mice, both of which are low responders to lipopolysaccharide (LPS) [1].
However, TLR4 alone is not sufficient to confer LPS responsiveness. TLR4 requires MD-2, a secreted molecule, to functionaly interact with LPS [2].
Furthermore, a third protein, called CD14, was shown to participates in LPS signaling, leading to NF-κB translocation. This signaling is mediated through the adaptor protein MyD88 but also through a MyD88-independent pathways that involves the (TIR) domain-containing adapter protein (TIRAP) [3].
TLR4-DN is a TIR-less form of the TLR4 gene generated by deleting the TIR domain (498 bp); This truncated gene is still able to recognize its ligands but is unable to induce the signaling cascade.
