Toll-like receptor 4 (TLR-4) is well known for its host innate immunity. Despite the fact that TLR-4 activation confers antitumor responses; emerging evidence suggests that TLR-4 is associated with tumor development and progression. It is now clear that overactivation of TLR-4, through various immune mediators, may cause immune response dysfunction, resulting in tumorigenesis. Different cancers...

OBJECTIVE Bacterial trigger possibly causes disease exacerbation in enthesitis-related arthritis (ERA) patients. Microbes initiate immune responses through Toll-like receptors (TLRs). We studied TLR expression on blood and SF monocytes and the effect of TLR ligands on peripheral blood (PB) mononuclear cells (PBMCs) in ERA patients. METHODS PB from 26 ERA patients and 19 healthy subjects and p...

BACKGROUND Prediction of restenosis after percutaneous coronary intervention (PCI) remains challenging, and existing risk assessment algorithms were developed before the widespread adoption of drug-eluting stents (DES). METHODS AND RESULTS We used data from the EVENT registry to develop a risk model for predicting target lesion revascularization (TLR) in 8829 unselected patients undergoing DE...

BACKGROUND Coronary artery bypass grafting with the use of cardiopulmonary bypass is known to mediate an inflammatory response. The stress-inducible heat-shock protein (HSP) 70 has been detected in myocardial cells after CABG, and toll-like receptors (TLRs) are suggested as putative signaling receptors for the HSPs, mediating synthesis of inflammatory cytokines. The main aims of our study were ...

BACKGROUND In long-term follow-up after drug-eluting stents (DES) implantation, late target lesion revascularization (TLR) is occasionally required. However, the incidence and predictors for late TLR with DES have not been fully investigated. METHODS AND RESULTS Between August 2004 and March 2005, 249 consecutive patients underwent percutaneous coronary intervention with sirolimus-eluting ste...

INTRODUCTION Toll-like receptors (TLRs) are an important component of immune system. Among them, TLR-2 plays a dominant role in the oral tissues in initiating inflammation in chronic periodontitis. Not many studies have been done on quantitative expression of TLR-2 by using immunofluorescent techniques (IFT) in oral tissues. In this study, the expression and localisation of TLR-2 were detected ...

Toll-like receptor-4 (TLR-4) has been increasingly recognized as playing a critical role in the pathogenesis of ischemia-reperfusion injury (IRI) of renal grafts. This review provides a detailed overview of the new understanding of the involvement of TLR-4 in ischemia-reperfusion injury of renal grafts and its clinical significance in renal transplantation. TLR-4 not only responds to exogenous ...

Numerous reports have described Toll-like receptor (TLR) expression in the tumor microenvironment as it relates to cancer progression, as well as their involvement in inflammation. While TLRs mediate immune surveillance, clinical studies have associated TLR expression in the tumor with poor patient survival, indicating that TLR expression may affect cancer treatment and survival. This review wi...

Salmonella enterica serovar Enteriditis (SE) causes a majority of foodborne illness in the U.S. A more productive avian innate immune response could reduce bacterial colonization and the incidence of infection in humans. However, quantification and comparison of the toll-like receptors (TLR), a component of the innate immune system that recognize bacterial pathogens, and their response to SE co...
