研究背景

機能:

Key component of innate and adaptive immunity. TLRs (Toll-like receptors) control host immune response against pathogens through recognition of molecular patterns specific to microorganisms. TLR9 is a nucleotide-sensing TLR which is activated by unmethylated cytidine-phosphate-guanosine (CpG) dinucleotides. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Controls lymphocyte response to Helicobacter infection (By similarity). Upon CpG stimulation, induces B-cell proliferation, activation, survival and antibody production.

PTMs:

Activated by proteolytic cleavage of the flexible loop between repeats LRR14 and LRR15 within the ectodomain. Cleavage requires UNC93B1. Proteolytically processed by first removing the majority of the ectodomain by either asparagine endopeptidase (AEP) or a cathepsin followed by a trimming event that is solely cathepsin mediated and required for optimal receptor signaling.

細胞の位置付け:

Endoplasmic reticulum membrane>Single-pass type I membrane protein. Endosome. Lysosome. Cytoplasmic vesicle>Phagosome.
Note: Relocalizes from endoplasmic reticulum to endosome and lysosome upon stimulation with agonist. Exit from the ER requires UNC93B1. Endolysosomal localization is required for proteolytic cleavage and subsequent activation. Intracellular localization of the active receptor may prevent from responding to self nucleic acid.

組織特異性:

Highly expressed in spleen, lymph node, tonsil and peripheral blood leukocytes, especially in plasmacytoid pre-dendritic cells. Levels are much lower in monocytes and CD11c+ immature dendritic cells. Also detected in lung and liver.

サブユニット構造:

Monomer and homodimer. Exists as a monomer in the absence of unmethylated cytidine-phosphate-guanosine (CpG) ligand. Proteolytic processing of an insertion loop (Z-loop) is required for homodimerization upon binding to the unmethylated CpG ligand leading to its activation (By similarity). Interacts with MYD88 via their respective TIR domains (By similarity). Interacts with BTK. Interacts (via transmembrane domain) with UNC93B1. Interacts with CD300LH; the interaction may promote full activation of TLR9-triggered innate responses (By similarity). Interacts with CNPY3 and HSP90B1; this interaction is required for proper folding in the endoplasmic reticulum. Interacts with SMPDL3B (By similarity).

タンパク質ファミリー:

Belongs to the Toll-like receptor family.

Fig 6. |TLR3 mediates the MHV-68-induced SOCS1 production. (A) BMMs were transfected with siRNAs against Tlr2, Tlr3, Tlr4, Tlr7, Tlr9 (si-TLR) or an irrelevant target (si-Control), respectively. Forty-eight hours post transfection, cells were infected with MHV-68 at MOI = 10. At 8 hpi, RNA and protein were then extracted. RT-qPCR was performed to determine SOCS1 mRNA levels and western blotting was performed to determine the protein expression levels of SOCS1 and the individual TLRs, respectively. The SOCS1 mRNA levels are expressed as values relative to the MHV-68 infected, si-Control transfected cells.

Figure 5 The migration of HepG2 cells induced by 25-HC is partly mediated by the up-regulation of TLR4. (A) HepG2 cells were treated with the indicated concentrations of 25-HC for 24 hours before mRNA was extracted and expressions of TLR2, TLR4, TLR5, TLR7 and TLR9 were examined by RT-qPCR. (B) HepG2 cells were treated with the indicated concentrations of 25-HC for 24 hours or treated with 25-HC at 10 μM for the indicated times before protein was collected to detect the TLR2, TLR4, TLR5, TLR7 and TLR9 expressions by Western blotting. HepG2 cells were transfected with siNC or siTLR4 or siTLR9 for 24 hours, (C) then cells were treated with the indicated concentrations of 25-HC for 24 hours before proteins were collected and the expressions of MMP1, MMP2, MMP3 and MMP9 were determined by Western blotting. (D) Or migratory ability of HepG2 cells after treated with 25-HC for 36 hours was determined by Transwell assay. Results were obtained from 3 independent experiments and are expressed as the means ± SEM. Statistical significance was determined by Student’s t-test. *P<0.05, ***P<0.001.
