Abstract Introduction Calcific aortic valve disease (CAVD) is caused by an osteoblastic phenotype switch of valvular interstitial cells (VICs), the predominant cell type in heart valves. However, trigger for remains unknown. Toll-like receptor 3 (TLR3) part innate immune system activated viral and endogenous RNA released from injured cells. We hypothesized that mechanical strain leads to TLR3 a...
Toll-like receptors (TLRs) are innate immune receptors for sensing microbial molecules and damage-associated molecular patterns released from host cells. Double-stranded RNA and the synthetic analog polyinosinic:polycytidylic acid (poly(I:C)) bind and activate TLR3. This stimulation leads to recruitment of the adaptor molecule TRIF (Toll/IL-1 resistance (TIR) domain-containing adapter-inducing ...
Chronic inflammation is an important component that contributes to many age-related neurodegenerative diseases, including macular degeneration. Here, we report a role for toll-like receptor 3 (TLR3) in cone-rod dystrophy (CORD) of mice lacking ATP-binding cassette transporter 4 (ABCA4) and retinol dehydrogenase 8 (RDH8), proteins critical for all-trans-retinal clearance in the retina. Increased...
BACKGROUND Rheumatoid arthritis (RA) has been associated with an increased risk of infections, but the underlying pathways have not yet been identified. Toll-like receptors (TLR) probably play a role in synovial inflammation and may also contribute to the understanding of the role of infections in RA. OBJECTIVES To investigate if the synovial expression of TLR3 and TLR7 in RA correlates with ...
Toll-like receptor 3 (TLR3) belongs to a family of evolutionary conserved innate immune recognition molecules and recognizes double-stranded RNA, a molecular pattern associated with viral infections. Earlier studies suggested a differential expression pattern in men and mice; the molecular basis for this observation, however, was unknown. Here we demonstrate that species-specific differences in...
BACKGROUND Toll-like receptor (TLR)3 gene variants may correlate with clinical significance of chronic viral infections including HBV. We aimed to investigate the expression of TLR3 in peripheral blood mononuclear cells (PBMCs) and liver cells of chronic hepatitis B (CHB) patients and its response to pegylated interferon or nucleoside analogue therapy. METHODS We consecutively enrolled 127 CH...
there exists compelling evidence that toll-like receptor 3 (tlr3) agonists can directly affect human cancer cells. the aim of this study was to investigate anti-cancer effects of tlr3 agonist in human breast cell line. we assessed potential effects of poly (a:u) on human breast cell line (mda-mb-231) on a dose-response and time-course basis. human breast cell line mda-mb-231 was treated wit...
Viral infection or TLR3 engagement causes activation of the transcription factors IRF-3 and NF-jB, which collaborate to induce transcription of type I IFN genes. IKKe and TBK1 are two IKK-related kinases critically involved in virusand TLR3-triggered activation of IRF-3. We identified a protein termed SIKE (for Suppressor of IKKe) that interacts with IKKe and TBK1. SIKE is associated with TBK1 ...
The particular microenvironment of the skeletal muscle can be the site of complex immune reactions. Toll-like receptors (TLRs) mediate inflammatory stimuli from pathogens and endogenous danger signals and link the innate and adaptive immune system. We investigated innate immune responses in human muscle. Analyzing TLR1-9 mRNA in cultured myoblasts and rhabdomyosarcoma cells, we found constituti...
Human neurons express the innate immune response receptor, Toll-like receptor 3 (TLR3). TLR3 levels are increased in pathological conditions such as brain virus infection. Here, we further investigated the production, cellular localisation, and function of neuronal TLR3 during neuronotropic rabies virus (RABV) infection in human neuronal cells. Following RABV infection, TLR3 is not only present...
