Comparative Effect of Insulin Resistance Reduction and Hormonal Alterations on Type 2 Diabetes Remission After Bariatric Surgery.

Bariatric surgery is known to induce weight loss and diabetes remission in patients with type 2 diabetes (T2D), but the exact mechanism of glycemic normalization needs to be defined. The study included patients with BMI ≥ 35 kg/m, obesity history ≥ 10 years, and planned bariatric surgery. At baseline and 3 and 6 months after surgery, all patients underwent anthropometric measurements, body composition and blood tests (including insulin, glucagon, and incretins during oral glucose tolerance test (OGTT)), and hyperinsulinemic euglycemic clamp tests.

Autophagy as a Guardian of Vascular Niche Homeostasis.

The increasing burden of vascular dysfunction on healthcare systems worldwide results in higher morbidity and mortality rates across pathologies, including cardiovascular diseases. Vasculopathy is suggested to be caused by the dysregulation of vascular niches, a microenvironment of vascular structures comprising anatomical structures, extracellular matrix components, and various cell populations. These elements work together to ensure accurate control of the vascular network.

Endothelial-specific Enhancer as a Cis Element of Regulation by TNF-alpha, IL-1beta, and VEGF.

The expression of human gene, which encodes the urokinase plasminogen activator receptor (uPAR), is cell- and process-specific and elevated in inflammation, cancer and senescence. Its tight regulation is achieved by regulatory elements in the gene locus, such as the promoter and several enhancers. The promoter activity is not specific to a particular cell type and has been described earlier.

Semaglutide 6-months therapy of type 2 diabetes mellitus restores adipose progenitors potential to develop metabolically active adipocytes.

Background: Nowadays type 2 diabetes mellitus (T2DM) leads to population mortality growth. Today glucagon-like peptide type 1 receptor agonists (GLP-1 RA) are one of the most promising glucose-lowered drugs with anorexigenic and cardioprotective effects. The present study aims to determine the effects of GLP-1 RA semaglutide 6-month therapy on T2DM patient metabolic parameters and adipose progenitor cell health.

IL-4 activates the futile triacylglyceride cycle for glucose utilization in white adipocytes.

The development of cardiometabolic complications during obesity is strongly associated with chronic latent inflammation in hypertrophied adipose tissue (AT). IL-4 is an anti-inflammatory cytokine, playing a protective role against insulin resistance, glucose intolerance and weight gain. The positive effects of IL-4 are associated not only with the activation of anti-inflammatory immune cells in AT, but also with the modulation of adipocyte metabolism.
