Plexins and semaphorins are ligand-receptor pairs that serve as guidance molecules in the nervous system and play some roles in immunity. Plexins are similar to the Toll-like receptors (TLRs) in their evolutionary conservation from flies to mammals. By studying plexin-A4-deficient (Plxna4(-/-)) innate immune cells, in this study we show a novel influence of plexin-A4 on TLR signaling. Plxna4(-/...
The expressions of Toll-like receptor (TLR) -2, -4 and -9 were immunohistochemically investigated in the follicle-associated epithelium (FAE), and epithelia of the follicle-associated intestinal villus (FAIV) and ordinary intestinal villus (IV) in rat Peyer's patch regions with no bacterial colonies on the mucous membranes. TLR-2 was expressed in the striated borders of microvillous columnar ep...
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...
BACKGROUND The standardized uptake value (SUV) is the nearly exclusive means for quantitative evaluation of clinical [18F-]fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) whole body investigations. However, the SUV methodology has well-known shortcomings. In this context, it has been recognized that at least part of the problems can be eliminated if tumor SUV is normalized to th...
Background: Inflammatory bowel disease, an autoimmune disease, has two clinical manifestations including Crohn’s disease and ulcerative colitis (UC). IL-17 has been the target of intensive research in autoimmune diseases. The influence of Toll like receptor 4 (TLR-4) gene polymorphisms on IL-17 production has also been revealed in UC patients and tissue inflammation in mice. Objectives: To inve...
BACKGROUND Optimal treatment strategies for restenosis of sirolimus-eluting stents (SES) have not been adequately addressed yet. METHODS AND RESULTS During the 3-year follow-up of 12 824 patients enrolled in the j-Cypher registry, 1456 lesions in 1298 patients underwent target-lesion revascularization (TLR). Excluding 362 lesions undergoing TLR for stent thrombosis or TLR using treatment moda...
Small nuclear RNA and associated lupus autoantigens activate B cells and dendritic cells via Toll-like receptor-7 (TLR-7); therefore, TLR-7 may represent a potential therapeutic target in lupus. MRL lpr mice were administered an injection of either saline or synthetic oligodeoxynucleotides with immunoregulatory sequences (IRS) that specifically block signaling via TLR-7 (IRS 661) or via TLR-7 a...
The aim of this study was to investigate the association of the common polymorphisms of Toll-like receptor 4 (TLR-4) with breast cancer development in the Saudi Arabian population. Four TLR-4 polymorphisms (rs2770150, rs10759931, rs10759932, and rs4986790) were studied using 127 breast cancer patients and 117 controls. Relative expression of TLR-4 protein in the breast tumor and the matched nor...
Monocyte dysfunction by filarial antigens has been a major mechanism underlying immune evasion following hyporesponsiveness during patent lymphatic filariasis. Recent studies have initiated a paradigm shift to comprehend the immunological interactions of Wolbachia and its antigens in inflammation, apoptosis, lymphocyte anergy, etc. Here we showed that recombinant Wolbachia heat shock protein 60...
Natural or synthetic Toll-like receptor (TLR) ligands trigger innate responses by interacting with distinct TLRs. TLR ligands can thus serve as vaccine adjuvants or stand-alone antimicrobial agents. One of the limitations of TLR ligands for clinical application is their short half-life and rapid clearance from the body. In the current study, encapsulation of selected TLR ligands in biodegradabl...
