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...

Toll-like receptor 9 (TLR9) enhances proinflammatory responses, but whether it can act in a regulatory capacity remains to be established. In experimental murine AKI induced by cisplatin, Tlr9(-/-) mice developed enhanced renal injury and exhibited fewer intrarenal regulatory T cells (Tregs) compared with genetically intact mice. A series of reconstitution and depletion studies defined a role f...

Radiation therapy is potentially immunogenic yet it rarely generates long-term antitumor effects. We have recently demonstrated that Toll-like receptor 9 (TLR9) jump-starts the signal transduction and activator of transcription 3 (STAT3)-dependent vascularization and regrowth of tumors that recur upon irradiation. We propose that the targeted inhibition of the TLR9/STAT3 signaling axis in myelo...
