Atherosclerosis is a chronic inflammatory disease regulated by T lymphocyte subsets. Recently, CD4+CD25+Foxp3+ regulatory T (Treg) cells and Th17 cells have been described as two distinct subsets from Th1 and Th2 cells and have the opposite effects on autoimmunity. Th17/Treg balance controls inflammation and may be important in the pathogenesis of plaque(More)
The minichromosome maintenance protein (MCM) complex is an essential replicative helicase for DNA replication in Archaea and Eukaryotes. Whereas the eukaryotic complex consists of 6 homologous proteins (MCM2-7), the archaeon Sulfolobus solfataricus has only 1 MCM protein (ssoMCM), 6 subunits of which form a homohexamer. Here, we report a 4.35-A crystal(More)
MicroRNA (miR)-155 is a critical player in both innate and adaptive immune responses. It can influence CD4(+) T cell lineage choice. To clarify the role of miR-155 in CD4(+) CD25(+) regulatory T (Treg)/T helper (Th)17 cell differentiation and function, as well as the mechanism involved, we performed gain-and loss-of-function analysis by transfection(More)
Recent studies have indicated a protective role of physiological autophagy in ischemic heart disease. However, the underlying mechanisms of autophagy regulation after ischemia are poorly understood. Exosomes are nano-sized vesicles released from cells that play critical roles in mediating cell-to-cell communication through the transfer of microRNAs. In this(More)
In this study, we investigated the hypothesis that regulatory T cells (T(reg)) are involved in the immunomodulatory effects of statins on rheumatoid arthritis (RA) patients. The 12-week study cohort consisted of 55 RA patients and 42 control subjects allocated to either a group treated with atorvastatin (AT) (20 mg/day) or a non-AT group. T(reg) numbers,(More)
Acute viral myocarditis (AVMC) is characterized by virus-triggered myocardial inflammation, and Coxsackievirus B3 (CVB3) is the primary pathogen. We previously proved that Th17 cells, besides having proinflammatory effects, were involved in AVMC by enhancing humoral response. However, the relationship between Th17 cells and CVB3 replication remains unknown.(More)
OBJECTIVE Atherosclerosis is a chronic inflammatory disease regulated by T lymphocyte subsets. Recently, CD4(+) CD25(+) Foxp3(+) regulatory T (Treg) cells and Th17 cells have been described as two distinct subsets and have the opposite effects on autoimmunity. Clinical observation has revealed that the Th17/Treg imbalance exists in patients with acute(More)
Anti-adenine nucleotide translocator (ANT) autoantibodies are related to the development of Coxsackievirus B3 (CVB3)-triggered acute viral myocarditis (AVMC). Recently, studies suggested that IL-17 especially produced by a novel CD4(+) Th-cell subset Th17 cells contributed to the production of pathogenic autoantibodies in some autoimmune diseases. However,(More)
PURPOSE To investigate the effects and safety of autologous peripheral blood stem cell (PBSCs) transplantation by intracoronary infusion in patients with acute myocardial infarction (AMI). METHODS 70 patients with AMI were allocated to two groups, one was PBSCs transplantation group (n=35) that received optimal post-infarction medical treatment (standard(More)
Alzheimer's disease is characterized in part by the aggregation of tau protein into filamentous inclusions. Because tau filaments form in brain regions associated with memory retention, and because their appearance correlates well with the degree of dementia, they have emerged as robust markers of disease progression. Yet the discovery that mutations in tau(More)
