background: dendritic cells (dcs) are potent antigen presenting cells for triggering of the immune reaction post transplantation. these cells are centrally involved in the initiation of t cell-dependent immune responses. objective: to compare the level of dc maturation and function in liver transplant recipients with healthy controls. methods: in this study, twelve peripheral blood samples were...

Suppressor of cytokine signaling (SOCS) proteins constitute a class of negative regulators for Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathways. These intracellular proteins are induced by cytokine signaling, but they can also be induced by stimulation of Toll-like receptors (TLR). It has even been suggested that SOCS proteins are important negative re...

Excessive scarring or fibrosis is a common feature of a wide spectrum of diseases characterized by an exaggerated Th2 response. The TLR/IL-1 receptor (IL-1R)-related protein ST2 is expressed in a membrane-bound form selectively by Th2 cells and was shown to be indispensable for some in vivo Th2 responses. ST2 was also found to block TLR signaling. We addressed the impact of the ST2 pathway on f...

Abstract Objectives: The mechanosensitive Ca 2+ion channels, Piezo1, converts the mechanical stimulus into cell signals in a variety of immune cells. However, pathophysiological property Piezo1 oral polymicrobial infectious disease periodontitis is largely unknown. This study investigated role inflammatory and phagocytic reactions by RAW264.7 macrophages response to exposures periodontal pathog...

Acute myocardial infarction (AMI) is accompanied by increased expression of Toll like receptors (TLR)-2 and TLR4 on circulating monocytes. In animal models, blocking TLR2/4 signaling reduces inflammatory cell influx and infarct size. The clinical consequences of TLR activation during AMI in humans are unknown, including its role in long-term cardiac functional outcome Therefore, we analyzed gen...

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 ...

OBJECTIVE Low-dose insulin infusion has been shown to exert a prompt and powerful anti-inflammatory effect. Toll-like receptors (TLRs) are major determinants of the inflammatory response to viral and bacterial pathogens. We have now hypothesized that low-dose insulin infusion in obese type 2 diabetic patients suppresses TLR expression. RESEARCH DESIGN AND METHODS Ten type 2 diabetic patients ...
