Regulation of Intestinal Flora and Immune Response by Cyanidin Exhibits Protective Effect against Type-2 Diabetes in Rat Model.

In the current study the effects of metformin and cyanidin on the immune system and intestinal flora in rats with type-2 diabetes was investigated. The findings showed that metformin or cyanidin treatment considerably reduced the rise in body weight and glucose levels induced by type-2 diabetes. The type-2 diabetic rats' glucose tolerance was significantly increased by cyanidin administration comparable to that of metformin.

Research on the Impact of the Strength of Channel Conflict on Cross-Channel Integration: The Mediating Effect of Channel Fluency and Stability.

Based on event system theory, we explore the effect of the strength of channel conflict on cross-channel integration from the perspective of manufacturers, and then analyzes the mediating effect of channel fluency and channel stability. Taking manufactures who implement cross-channel integration as research samples, and basing the data collected from 229 respondents, the study uses multiple regression analysis and Bootstrap method to test the research hypotheses. The empirical research findings show that: the strength of channel conflict plays a negative role on channel fluency and channel stability; the strength of channel conflict has a double-edged sword effect on cross-channel integration: it can reduce cross-channel integration by destroying channel fluency, and at the same time can improve cross-channel integration by destroying and reducing channel stability.

Decreased β-catenin expression contributes to IFNγ-induced chemokine secretion and lymphocyte infiltration in Hashimoto's thyroiditis.

Hashimoto's thyroiditis (HT) is a very common organ-specific autoimmune disease characterized by lymphocyte infiltration and the destruction of thyroid follicular cells (TFCs), in which IFN-γ and chemokines play pivotal roles. Moreover, β-catenin has been implicated in the regulation of T cell infiltration. However, whether β-catenin is involved in Hashimoto's thyroiditis is unknown.

Caveolin-1 Regulates CCL5 and PPARγ Expression in Nthy-ori 3-1 Cells: Possible Involvement of Caveolin-1 and CCL5 in the Pathogenesis of Hashimoto's Thyroiditis.

Background: Hashimoto's thyroiditis (HT) is characterized by lymphocytic infiltration of the thyroid parenchyma, which ultimately leads to tissue destruction and loss of function. Caveolin-1 (Cav-1) is an essential structural constituent of lipid rafts in the plasma membrane of cells and is reported to be significantly reduced in thyrocytes from HT patients. However, the mechanism of Cav-1 involvement in HT pathogenesis is still largely unclear.

Caveolin-1 regulates autophagy activity in thyroid follicular cells and is involved in Hashimoto's thyroiditis disease.

Hashimoto's thyroiditis (HT) is considered a T helper-type 1 (Th1) cytokine-dominant autoimmune thyroid disease. Caveolin-1 (Cav-1), a part of the thyroxisome multiprotein complex, is localized at the apical pole of thyrocytes and is indispensable for synthesis of thyroid hormones and modulation of oxidative stress in order to avoid cell damage and apoptosis. Reduced autophagy induces thyroid follicular cells (TFC) apoptosis by activating reactive oxygen species (ROS) in HT patients.

Aberrant MRP14 expression in thyroid follicular cells mediates chemokine secretion through the IL-1β/MAPK pathway in Hashimoto's thyroiditis.

Myeloid-related protein 14 (MRP14) is responsible for inflammatory reactions. However, the correlation between MRP14 and Hashimoto's thyroiditis (HT) is still not clear. In this study, we examined the status of MRP14 in thyroid tissues and sera of HT patients and explored the mechanism of IL-1β-mediated regulation of MRP14 expression, as well as the effects of MRP14 on pro-inflammatory chemokine secretion in thyroid follicular cells (TFCs), to elucidate the role of MRP14 in HT development.

Increased Interleukin-23 in Hashimoto's Thyroiditis Disease Induces Autophagy Suppression and Reactive Oxygen Species Accumulation.

Hashimoto's thyroiditis (HT) represents the most common organ-specific autoimmune disease. Inflammatory factors and reactive oxygen species (ROS) play detrimental roles during the pathogenesis of HT. In this study, we found that thyroid follicular cells (TFCs) from HT patients expressed an elevated level of interleukin-23 (IL-23), which contributed to autophagy suppression and ROS accumulation.
