- Description
- Description: The TLR3.7 monoclonal antibody reacts with human Toll-like receptor 3 (TLR3). To date, at least twelve members of the Toll-like receptor family have been identified. This family of type I transmembrane proteins is characterized by an extracellular domain with leucine-rich repeats and a cytoplasmic domain with homology to the type I IL-1 receptor. In the innate immune response, TLRs recognize molecular patterns associated with microbial pathogens and induce antimicrobial activity. TLR3 recognizes double-stranded (ds)RNA, induces the activation of NF-kappaB through MyD88-dependent and -independent pathways, and the production of type I interferons (IFNs). TLR3.7 suppressed poly(I):poly(C)-mediated IFN-beta production by human fibroblasts naturally expressing TLR3 on their surface.

- Figure 7 IRF1 regulates TRL2 and TLR3 signaling. (A) Parent and IRF1 KO cells were treated with poly I:C (1 mug/mL) for 6 h and IRF1 independent ISG expression was examined by RT-qPCR comparative C q method (2 -DeltaDelta Cq ). Data represent mean +- SEM from three independent experiments. (B) Parent and IRF1 KO cells were processed for confocal microscopy to examine localization of TLR3. Antibody against EEA1 was used to examine localization of early endosomes. Images from individual channels for TLR3 (green), EEA1 (red), and nuclei (blue) are shown. Right panels show images with merged channels with magnified view as inset. (C,D) Parent and IRF1 KO cells were treated with the respective TLR2 and TLR4 agonists, Pam2CSK4 at 1ng/ml (C) , or LPS at 10 ng/ml (D) and activation of NF-kB pathway was examined by western blot with anti-phospho-NFKBIA (S32). * Statistically significant.

- Figure 3 Interleukin-1 receptor 1 is highly expressed on infra-patellar pad derived fibroblasts. Fibroblasts isolated from the infra-patellar fat pad and synovial membrane (both n = 5) were cultured in vitro and the relative gene expression of TLR1-10, RIG-1, RAGE and IL-1R1 quantified by qRT-PCR. ( a ) TLR expression was restricted mainly to TLR3 and TLR4 with little or no expression of other TLRs. ( b ) There was no detectable expression of RAGE but RIG-1 was expressed at levels comparable to TLR3 and TLR4. In contrast IL-1R1 expression was 100-150 fold greater than other receptors. Results are normalised to GAPDH as a loading control. Data is presented as mean +- standard error of the mean. Fibroblasts isolated from the infra-patellar fat pad were investigated for the expression of TLR3, TLR4 and IL-1R1 protein by Western Blotting (n = 4) ( c ) and flow cytometry (n = 6) ( d ). Cells expressed TLR3 and TLR4 at comparable levels at the cell surface. In contrast, expression of IL-1R1 was significantly higher than other receptors (red traces). beta-actin was used as a loading control (c) . Unstained cells (filled traces) and IgG controls (black traces) were used as flow cytometry controls (d) .
