Trif dependent pathway
WebThe initiation of TRIF-dependent signaling pathway via TLR4 located on the endosomal membrane leads to a phosphorylation of transcription factor IRF3, which regulates the expression of type 1 interferon genes involved in antiviral immunity . 3,11. Table 1 Ligands of TLR2 and TLR4. WebCRX-527 signaled as potently through MyD88- and TRIF-dependent pathways as LPS downstream of TLR4 in human monocytes and dendritic cells. Although CRX-547 signaled relatively robustly through the TRIF-dependent pathway, the analog signaled poorly through the MyD88-dependent pathway relative to CRX-527 and LPS (Fig. 3.4).

WebSARM expression was shown to specifically block TRIF-dependent transcription-factor activation and gene induction, without affecting the MyD88-dependent pathway or non-TLR signalling by TNF or RIG-I .
TRIF is primarily active in the spleen and is often regulated when MyD88 is deficient in the liver, indicating organ-specific regulation of signaling pathways. Curiously, there is a lack of redundancy within the TLR4 signaling pathway that leads to microbial evasion of immune response in the host after mutations occur within intermediates of the pathway. Three TRAF-binding motifs present in the amino terminal region of TRIF are necessary for association with TRAF6. Destruction of thes…
WebOct 15, 2024 · The LPS-induced internalization of TLR4 and hence also the activation of the TRIF-dependent pathway is governed by a GPI-anchored protein, CD14.
