OBJECTIVE To analyze toll-like receptor (TLR)-2 and TLR-4 expression in monocytes of newborns with late-onset sepsis. METHODS This prospective study included 27 full-term newborns aged 8 to 29 days, with clinical and laboratory diagnosis of late-onset sepsis. Ten newborns (37%) had positive cultures. Cytokines were measured by cytometric bead array in peripheral blood, while TLR-2, TLR-4 expr...
OBJECTIVE Individuals with type 2 diabetes have a myriad of metabolic aberrations including increased inflammation, increasing their cardiovascular risk. Toll-like receptors (TLRs) and their ligands play a key role in insulin resistance and atherosclerosis. However, there is a paucity of data examining the expression and activity of TLRs in type 2 diabetes. Thus, in the present study, we examin...
Toll-like Receptor Polymorphisms and Carotid Artery Intima-Media Thickness To the Editor: Chronic inflammation represents a hallmark of atherosclerosis. Thus, there is growing interest in the role of innate immune defense mechanisms in arterial plaque formation, and several studies directly implicate signaling by toll-like receptors (TLRs) in the pathogenesis of atherosclerosis. However, these ...
AIMS Inflammation plays a key role in acute coronary syndromes (ACS). Toll-like receptors (TLR) on leucocytes mediate inflammation and immune responses. We characterized leucocytes and TLR expression within coronary thrombi and compared cytokine levels from the site of coronary occlusion with aortic blood (AB) in ACS patients. METHODS AND RESULTS In 18 ACS patients, thrombi were collected by ...
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: Toll-like receptors (TLRs) detect diverse pathogen-associated molecular patterns and play a critical role in the innate immune response. Hosts should activate TLR-signaling pathways to eliminate invading pathogens. However, excessive activation of these pathways may interrupt immune homeostasis, leading to several diseases. Therefore precise regulation of TLR-signaling pathways is e...
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...
tlr ها گروهی قدیمی از ژن ها هستند که در مهره داران و بی مهرگان یافت شده اند و این گیرنده ها در گیاهان نیز یافت می شوند. در پستانداران اعضای خانواده ژنtlr نقش عمده ای را در شناخت خصوصیات مولکولی مرتبط با پاتوژن ها در پروتیین های باکتری ها ویروس ها قارج ها و پروتوزآ ایفا می کنند tlrها شامل دامنه وسیعی از گیرنده ها هستند که مسئول باند شدن باpamp ( الگوی القا کننده پاتوژن که با گیرنده های سلول های ...
