background one-third of the world’s population is infected with mycobacterium tuberculosis. investigation of toll-like receptors (tlrs) has revealed new information regarding the immunopathogenesis of this disease. toll-like receptors can recognize various ligands with a lipoprotein structure in the bacilli. toll-like receptor 2 and tlr-4 have been identified in association with tuberculosis in...
toll-like receptor (tlr) 7 and 8 mediate anti-virus immunity and are of particular relevance to asthma. however, very little information about genetic association on tlr7/8 and asthma are available. this study aimed to evaluate the effects of polymorphisms in tlr7 and 8 on asthma risk and asthma-related phenotypes in a chinese han population. we enrolled 462 unrelated adult asthmatic patients a...
systemic lupus erythematosus (sle) is a chronic autoimmune disease which results in damage to various organs. some animal studies have revealed that activation of toll-like receptors (tlrs) is important in the pathogenesis of sle. in the present study, the percentage of different immune cell subsets in 35 sle patients and 38 control subjects was analyzed by flow cytometry. we also assessed the ...
background: stroke is a leading cause of death all around the world, and ischemic stroke is considered to be the most common stroke type. toll-like receptors (tlrs) are important molecules for detection of both pathogen invasion and tissue damage. in this regard, the purpose of this study was to assess the expression level of tlr2 on monocytes in patients with ischemic stroke and to evaluate th...
background: recently, reports have indicated a role for the membrane form of toll-like receptor 2 (tlr2) in asthma pathogenesis. in this study we examined soluble tlr2 levels in serum and sputum of asthmatic and healthy subjects. methods: serum and sputum samples were obtained from 33 asthmatic and 19 healthy subjects. the asthmatics were classified into four groups according to the global init...
background: myocardial dysfunction is one of the major complications in patients with sepsis where there is a relationship between the blood level of cytokines and the onset of myocardial depression. in many cases of sepsis, the presence of lipopolysaccharide (lps) has been established. lps binding protein (lbp) bound endotoxin is recognized by cd14/toll-like receptor-4 (tlr4) complexes in inna...
background: the pathogenesis of migraine involves immune-mediated mechanisms in the vascular endothelium. toll like receptor 4 (tlr-4) is a signaling receptor of innate immunity which plays a role in various neuropathologies related to neuron inflammation. objective: this case/control study is aimed to investigate whether tlr- 4 896a/g variation is related to migraine headaches in an iranian po...
abstract objective: the previous studies indicated that the tlrs especially toll-like receptor 4) tlr4 (are involved in the process of diabetes. the aim of the present research was to investigate the time course expression pattern of tlr4-a main component of innate immune system- in mrna levels in the heart tissue of diabetic male wistar rats. materials and methods: in this research, adult wist...
Background & Objectives: Interaction of cytomegalovirus glycoprotein B with toll-like receptors of dendritic cells leads to early signaling and innate immune responses. The aim of this study is to evaluate the effects of cytomegalovirus glycoprotein B on the maturation and function of monocyte-derived dendritic cells in treated groups in comparison with control groups. Materials & Methods: Bloo...
Background: Hepatic encephalopathy is defined as a neuropsychiatric brain dysfunction in acute or chronic liver failure. Infection and inflammation have crucial role in its pathophysiology. The purpose of our study was to demonstrate the relationship between toll-like receptor 4 (TLR4) expression and the encephalopathy induced with endotoxin in biliary cirrhotic rats. Methods: The present stud...
