CONTEXT Previous trials have investigated the effects of low-dose aspirin on primary prevention of cardiovascular events, but not in patients with type 2 diabetes. OBJECTIVE To examine the efficacy of low-dose aspirin for the primary prevention of atherosclerotic events in patients with type 2 diabetes. DESIGN, SETTING, AND PARTICIPANTS Multicenter,(More)
Phagocytes such as macrophages and dendritic cells (DCs) engulf apoptotic cells to maintain peripheral immune tolerance. However, the mechanism for the recognition of dying cells by phagocytes is not fully understood. Here, we demonstrate that T-cell immunoglobulin mucin-3 (Tim-3) recognizes apoptotic cells through the FG loop in the IgV domain, and is(More)
Coronary spasm plays an important role in the pathogenesis of not only variant angina but also ischemic heart disease in general. However, the precise mechanism(s) by which coronary spasm occurs remains to be elucidated. Coronary spasm may arise from interactions between environmental and genetic factors. Endothelial derived nitric oxide (NO) has been(More)
BACKGROUND Cannabinoid 1 (CB1) receptor blockade with rimonabant represents a clinical therapeutic strategy for obesity. Recently, the role of the endocannabinoid system has been described in peripheral organs. We sought to determine whether the endocannabinoid system could be involved in human atherosclerosis and whether CB1 receptor blockade could(More)
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a proapoptotic member of the TNF family of type II membrane proteins, which constitutes one component of T cell cytotoxicity. In this study, we investigated the expression and function of TRAIL in human peripheral blood T (PBT) cells. Although freshly isolated PBT cells did not express(More)
The innate immune system uses a wide variety of pattern recognition receptors including TLRs, scavenger receptors, and lectins to identify potential pathogens. A carefully regulated balance between activation and inhibition must be kept to avoid detrimental and inappropriate inflammatory responses. In this study, we identify murine-paired Ig-like receptor(More)
It is now recognized that aldosterone is potentially cardiotoxic, although its local effects in the heart are not well understood. We examined the effects of aldosterone on cultured neonatal rat cardiomyocytes in the presence of normal and elevated extracellular Na+ ([Na+]o). We evaluated the intracellular volume of cardiomyocytes in the presence of normal(More)
We recently reported that oxidative stress is involved in the pathogenesis of coronary spasm. We hypothesized that oxidative-stress-related genetic factors and certain polymorphisms in the paraoxonase gene (PON1) and platelet-activating factor acetylhydrolase (PAF-AH) might influence the pathogenesis of coronary spasm. We therefore examined the possible(More)
TWEAK, a TNF family member, is produced by IFN-gamma-stimulated monocytes and induces multiple pathways of cell death, including caspase-dependent apoptosis, cathepsin B-dependent necrosis, and endogenous TNF-alpha-mediated cell death, in a cell type-specific manner. However, the TWEAK receptor(s) that mediates these multiple death pathways remains to be(More)
Tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) is a member of the TNF superfamily that has been shown to induce angiogenesis, apoptosis in tumor cells, and NF-kappaB activation through binding to its receptor, fibroblast growth factor-inducible 14. We have identified TWEAK as an inducer of constitutive NF-kappaB activation by expression(More)
