Response, and Arteriosclerosis To the Editor: There is increasing evidence that Toll-like receptor (TLR)dependent signaling and cell activation is critically involved in the pathogenesis of arteriosclerosis. The article by M. Kazemi et al impressively demonstrates that Toll-like receptor agonists induce lipid accumulation and proteins involved in atherosclerotic plaque development such as adipo...
Toll-like receptor-4 (TLR-4) has an important pattern recognition receptor that recognizes endotoxins associated with gram negative bacterial infections. The present investigation was carried out to study nucleotide sequencing and SNP detection by PCR-RFLP analysis of the TLR-4 gene in Murrah buffalo. Genomic DNA was isolated from 102 lactating Murrah buffalo from NDRI herd. The amplified PCR f...
In an obese state, Toll-like receptor-4 (TLR-4) upregulates proinflammatory adipokines secretion including monocyte chemotactic protein-1 (MCP-1) in adipose tissue. In contrast, G-protein coupled receptor 120 (GPR120) mediates antiobesity effects. The aim of this study was to determine the signaling pathway by which Forskolin (FK), a cyclic adenosine monophosphate- (cAMP-) promoting agent causi...
The recently delineated role for IL-23 in enhancing Th-17 activity suggests that regulation of its expression is distinct from that of IL-12. We hypothesized that independent TLR-mediated pathways are involved in the regulation of IL-12 and IL-23 production by myeloid-derived dendritic cells (DCs). The TLR 2 ligand, lipoteichoic acid (LTA), the TLR 4 ligand, LPS, and the TLR 7/8 ligand, resimiq...
Toll-like receptor 4 (TLR-4) is crucial in maintaining intestinal epithelial homeostasis, participates in a vigorous signaling process and heightens inflammatory cytokine output. The objective of this study was to determine the effects of glutamine (GLN) on TLR-4 signaling in intestinal mucosa during methotrexate (MTX)-induced mucositis in a rat. Male Sprague-Dawley rats were randomly assigned ...
INTRODUCTION Although we have a detailed understanding of how single microbial derived triggers activate specialized Toll-like receptors (TLR) on airway epithelial cells, we know little of how these receptors react in a more complex environment. In everyday life, nasal epithelial cells are exposed to multiple TLR agonists, therefore we explored whether exposure to one trigger could affect the r...
Introduction: Coronavirus disease 2019 (COVID-19) spreads all around the world and leads to several new infection cases mortality. A better understanding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogenesis could lead more efficient therapeutic approaches. Objectives: The current study aimed investigate Toll-like receptors expression profile in peripheral blood mononucle...
BACKGROUND Toll-like receptors (TLRs) are effectors of the innate immune system that are able to recognize hepatitis C virus (HCV) and give rise to an immune response. Failure of interferon (IFN)-α-based treatment is related to host immunity. Therefore, we sought to study the clinical importance of TLRs in HCV genotype 1 patients who received pegylated IFN (PEG-IFN) plus ribavirin (RBV) therapy...
Lipopolysaccharide (LPS) has been implicated in sepsis-mediated heart failure and chronic cardiac myopathies. We determined that LPS directly and reversibly affects cardiac myocyte function by altering regulation of intracellular Ca2+ concentration ([Ca2+]i) in immortalized cardiomyocytes, HL-1 cells. [Ca2+]i oscillated (<0.4 Hz), displaying slow and transient components. LPS (1 microg/ml), der...
