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)
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)
Recently, the Th17 cell, a newly determined CD4+Th subset, was reported to participate in the inflammation of myocarditis combined with Th1 cells, and this study aimed to explore whether it was involved in the Th2 cell-mediated humoral immunity in viral myocarditis. A total of 34 patients, including 16 acute viral myocarditis (AVMC) and 18 dilated(More)
OBJECTIVE Solid pseudopapillary tumor (SPT) of the pancreas, which predominantly affects young women, is a relatively indolent entity with favorable prognosis. The aim of this study is to describe the clinicopathologic features and surgical management of this disease in our institution. METHODS A retrospective study of clinical data from 26 consecutive(More)
MicroRNAs (miRNAs) are a novel class of small, non-coding RNAs that play a significant role in both inflammatory and cardiovascular diseases. Immune cells, especially T helper (Th) cells, are critical in the development of atherosclerosis and the onset of acute coronary syndrome (ACS). To assess whether inflammation-related miRNAs (such as miR-155, 146a,(More)
Excessive tumor necrosis factor-α (TNF-α) expression is increasingly thought to be detrimental to cardiomyocytes in acute myocardial infarction. During myocardial ischemia, TNF-α is mainly released from macrophages, but with persistent ischemia, it can originate from cardiomyocytes and contribute to cardiac remodeling. The initiating factor and exact(More)
The immunodominance of Mycobacterium tuberculosis proteins malate synthase (MS) and MPT51 has been demonstrated in case-control studies with patients from countries in which tuberculosis (TB) is endemic. The value of these antigens for the serodiagnosis of TB now is evaluated in a cross-sectional study of pulmonary TB suspects in the United States diagnosed(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)
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)
ETHNOPHARMACOLOGICAL RELEVANCE Jinlida (JLD) is a compound preparation formulated on the basis of traditional Chinese medicine and is officially approved for the treatment of type 2 diabetes (T2DM) in China. We aimed to elucidate the mechanism of JLD treatment, in comparison to metformin treatment, on ameliorating insulin sensitivity in insulin resistant(More)
