Furthermore, TLR4/TRAF6/NOX2 signaling pathway inhibition attenuated ER stress response and alleviate lung injury in mice.This study aimed to investigate whether extracellular vesicles (EVs) secreted in myocardial infarction (MI) plasma could protect against apoptosis of bone marrow mesenchymal stem cells (BMSCs) following hypoxia or serum deprivation in vitro and improve cardiac function following MI in vivo. The plasma samples were taken from female rats 24 h after MI. EVs were obtained and co-cultured with BMSCs. We found that EVs could be taken up by BMSCs. Co-culturing with EVs attenuated hypoxia-induced apoptosis of BMSCs in EVs in a dose-dependent manner, which was reversed by the pharmacological inhibition of AKT signaling. Co-culturing with EVs improved transplantation efficiency and blunted MI-induced apoptosis of BMSCs in vivo. Furthermore, transplantation of BMSCs together with EVs can effectively promote the increase in capillary density both at the border and central zone of myocardium and ameliorate myocardial remodeling in MI rats. BMSCs and EVs transplantation treatment exhibited significant improvements in ejection fraction, fraction shortening, left ventricular end-diastolic dimensions, and left ventricular end-systolic dimensions, as evaluated by echocardiography four weeks after MI in rats. Finally, levels of differentiation- and apoptosis-related microRNAs expression in EVs that may mediate these effects were also identified by microarray and quantitative real-time PCR. In conclusion, the present results suggest a potential role of plasma-derived EVs in decreasing apoptosis of BMSCs by activating AKT signaling, promoting angiogenesis, ameliorating myocardial remodeling, and improving cardiac function in MI rats. EV application may be a novel option to ameliorate the therapeutic efficiency of BMSCs to improve cardiac function following MI.An increasing amount of reports in the literature is showing that medical ozone (O3) is used, with encouraging results, in treating COVID-19 patients, optimizing pain and symptoms relief, respiratory parameters, inflammatory and coagulation markers and the overall health status, so reducing significantly how much time patients underwent hospitalization and intensive care. To date, aside from mechanisms taking into account the ability of O3 to activate a rapid oxidative stress response, by up-regulating antioxidant and scavenging enzymes, no sound hypothesis was addressed to attempt a synopsis of how O3 should act on COVID-19. The knowledge on how O3 works on inflammation and thrombosis mechanisms is of the utmost importance to make physicians endowed with new guns against SARS-CoV2 pandemic. This review tries to address this issue, so to expand the debate in the scientific community.
Sepsis can induce myocardial dysfunctions and endothelial progenitor cells (EPCs)-derived extracellular vesicles (EVs) can attenuate sepsis. Concerning to that, this article is intended to decode whether microRNA (miR)-375-3p in EPCs-EVs could affect myocardial injury in sepsis.

Rat bone marrow-derived EPCs and EPCs-EVs were harvested. A rat model of sepsis was established by cecal ligation and puncture. Septic rats were injected with EPCs-EVs that interfered with miR-375-3p, after which cardiac function, inflammatory response, pathological damage, oxidative stress and apoptosis were detected in myocardial tissues. miR-375-3p, bromodomain 4 (BRD4), phosphoinositide 3-kinase (PI3K) and protein kinase B (AKT) expression in myocardial tissues, and their reciprocals were identified.

Septic rats expressed reduced miR-375-3p and elevated BRD4 in myocardial tissues. EPCs-EVs improved cardiac function, suppressed inflammation, oxidative stress and apoptosis, as well as attenuated the pathological damage of myocardial tissues in septic rats. Up-regulated/down-regulated miR-375-3p in EPCs-EVs relieved/deteriorated myocardial injury in septic rats. miR-375-3p targeted BRD4 to activate PI3K/AKT pathway, thereafter to ameliorate myocardial injury in septic rats.

It is illustrated that miR-375-3p in EPCs-EVs activates BRD4-mediated PI3K/AKT signaling pathway to ameliorate myocardial injury in septic rats, which provides a therapeutic target for myocardial injury in sepsis.

In this study, we investigated the effects of intragastric and atomized administration of canagliflozin (CAN) on cytokine storm in lung tissues of lipopolysaccharides (LPS)-induced mice. Results showed that intragastric administration of CAN significantly and widely inhibited the production of inflammatory cytokines in lung tissues of LPS-induced sepsis mice. Simultaneously, intragastric administration of CAN significantly improved inflammatory pathological changes of lung tissues. click here Atomized administration of CAN also exhibited similar effects in LPS-induced sepsis mice. Furthermore, CAN significantly inhibited hypoxia inducible factor 1α (HIF-1α) and phosphofructokinase-2/fructose-2,6-bisphosphatase 3 (PFKFB3) protein levels in LPS-treated lung tissues. These results indicated that CAN might attenuate cytokine storm and reduce the inflammatory symptoms in critical cases in COVID-19. Its action mechanism might involve the regulation of HIF-1α and glycolysis in vivo. However, further studies about clinical application and mechanism analysis should be validated in the future.Regulatory B cells (Bregs) are a subset of B cells that can downregulate the immune and inflammatory responses. The development of B cells in humans and mice is differs. The Positioning and targeted regulation of Bregs has a positive effect on autoimmune diseases. Autoimmune thyroid disease (AITD) is a common autoimmune disease. This review introduces the history and origins of Bregs. It summarizes the different phenotypes and functionalities of Breg cells related to AITD and analyzes the reasons for the differences in Breg expression frequencies in Graves disease (GD) and Hashimoto's Thyroiditis (HT). A number of functional defects of regulatory B cells may be the newly discovered cause of AITD. This paper sheds new light on the role and prospects of Bregs in the progression and treatment of AITD.
