IRAP+ endosomes restrict TLR9 activation and signaling [PDF]
The retention of intracellular Toll-like receptors (TLRs) in the endoplasmic reticulum prevents their activation under basal conditions. TLR9 is activated by sensing ligands in specific endosomal-lysosomal compartments. Here we identified IRAP+ endosomes as major cellular compartments for the early steps of TLR9 activation in dendritic cells (DCs ...

TLR9 signaling requires ligand-induced phosphorylation of two specific tyrosine residues by EGFR and Syk [PDF]
Toll-like receptors (TLRs) are transmembrane proteins that recognize microbial components or cellular danger signals and activate intracellular signaling pathways, leading to induction of anti-microbial and inflammatory genes.

Cyclical palmitoylation regulates TLR9 signalling and systemic autoimmunity in mice
Toll-like receptor 9 (TLR9) recognizes self-DNA and plays intricate roles in systemic lupus erythematosus (SLE). However, the molecular mechanism regulating the endosomal TLR9 response is incompletely understood.

Blocking Toll-like receptor 9 attenuates bleomycin-induced pulmonary injury [PDF]
Background Acute respiratory distress syndrome (ARDS) is one of the most common complications in coronavirus disease 2019 patients suffering from acute lung injury (ALI). In ARDS, marked distortion of pulmonary architecture has been reported.

TLR9 gene expression in immune cells of patients with psoriasis
Background. Psoriasis (skin lesions and psoriatic arthritis PA) is a chronic inflammatory autoimmune disease that can be triggered by excessive activation of endosomal toll-like receptors (TLRs), mainly TLR9. Elevated TLR9 levels are observed in both PA

Expression of TLR9 and NF-κB in condyloma acuminatum
Objective To explore the expression and significance of TLR9 and NF-κB in condyloma acuminatum (CA). Methods The streptavidin-peroxidase (SP) immunohistochemistry method was used to measure the expression of TLR9 and NF-κB in 50 cases of CA and 20 normal

Mechanisms of TLR9 activation [PDF]
Non-methylated CpG-motifs in bacterial or viral DNA are recognized by TLR9 as foreign. The activation of TLR9 by microbial DNA or synthetic oligonucleotides based on these motifs leads to the induction of innate immune responses. We have compared the subcellular localization of fluorescent versions of TLR9 and TLR4 and found that TLR9 is expressed in ...

The ectodomain of Toll-like receptor 9 is cleaved to generate a functional receptor. [PDF]
Mammalian Toll-like receptors (TLRs) 3, 7, 8 and 9 initiate immune responses to infection by recognizing microbial nucleic acids; however, these responses come at the cost of potential autoimmunity owing to inappropriate recognition of self nucleic acids.
