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...

objective: argemone mexicana is a papaveracea plant; some reports have shown their antibacterial, anti-cancer, sedative and probably anti-anxiety properties. from their aerial parts, flavonoids and alkaloids have been isolated, which are intrinsically related to some actions on the central nervous system. the aim of this study was to evaluate the anxiolytic-like effects of the plant, using its ...

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...

context triple negative breast cancer (tnbc) is a heterogeneous group of diseases that is negative for esterogen receptor (er) progesteron receptor (pr) and human epidermal growth factor receptor 2 (her2). this type of breast cancer is typically high-grade carcinomas, although low-grade tumors occur. the aim of this review is to focus on molecular classification and features, prognostic markers...

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...

host genetic factors play a central role in determining the clinical phenotype of human diseases. association between two polymorphic loci in human genome, human leukocyte antigen (hla) and killer cell immunoglobulin-like receptors (kirs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. hence, defining the influence of genetic di...

background: the fc receptor like (fcrl) molecules belong to the immunoglobulin (ig) superfamily with potentially immunoregulatoryfunction. among the fcrl family fcrl2 and 4 are predominantly expressed on memory b cells and fcrl1 is a pan- b cell marker. to date, noligand has been identifid for the human fcrl1, 2 and 4 molecules.objectives: cloning, expression, purifiation and structural analysi...

background: multiple sclerosis (ms) is a t cell mediated autoimmune disease with unknown etiology. appropriate ms therapeutic strategies need thorough understanding of both disease etiology and pathogenesis mechanisms. ligation of tlr-2 and tlr-4 stimulates the production of several cytokines leading to cns autoimmunity and neurodegenerative diseases. objective: to find a relationship between m...
