Factors associated with COVID-19 vaccination rates in countries with different income levels: a panel analysis.

Introduction: Vaccines against coronavirus disease (COVID-19) are being developed and supplied at an unprecedented rate. However, disparities in income levels among countries has influenced the supply and vaccination rate. This imbalance poses a potential risk factor, especially if vaccine-resistant variants emerge and the pandemic persists.

Lipid profile changes induced by glucagon-like peptide-1 receptor agonists in patients with type 2 diabetes: a systematic review and network meta-analysis.

Objective: This study was conducted to investigate the effects of glucagon-like peptide-1 receptor (GLP-1) agonists on the lipid profiles of patients with type 2 diabetes.

Methods: We retrieved the data of phase 3 randomized controlled trials on GLP-1 agonists in patients with type 2 diabetes from the PubMed, Embase, and Cochrane library up to 11 February 2024. We extracted % changes in low-density lipoprotein cholesterol (LDL-C)/high-density lipoprotein cholesterol/total cholesterol (T-CHO) and triglycerides levels from baseline.

GPR119 activation by DA-1241 alleviates hepatic and systemic inflammation in MASH mice through inhibition of NFκB signaling.

Background And Purpose: GPR119 activation has been suggested to improve hyperglycemia, dyslipidemia and hepatic steatosis. But its therapeutic potential for metabolic dysfunction-associated steatohepatitis (MASH) are underexplored. Here, we investigated the effects of DA-1241, a novel GPR119 agonist, on MASH and explored its underlying mechanism of anti-inflammatory effects.

A novel GPR119 agonist DA-1241 preserves pancreatic function via the suppression of ER stress and increased PDX1 expression.

DA-1241 is a novel small molecule G protein-coupled receptor 119 (GPR119) agonist in early clinical development for type 2 diabetic patients. This study aimed to elucidate the pharmacological characteristics of DA-1241 for its hypoglycemic action. DA-1241 potently and selectively activated GPR119 with enhanced maximum efficacy.

Myeloid Sirtuin 6 Deficiency Causes Insulin Resistance in High-Fat Diet-Fed Mice by Eliciting Macrophage Polarization Toward an M1 Phenotype.

Obesity-related insulin resistance is closely associated with macrophage accumulation and subsequent cytokine release in local tissues. Sirtuin 6 (Sirt6) is known to exert an anti-inflammatory function, but its role in macrophages in the context of obesity has not been investigated. We generated myeloid-specific Sirt6 knockout (mS6KO) mice and investigated the metabolic characteristics after high-fat diet (HFD) feeding for 16 weeks.

Beneficial Effects of Evogliptin, a Novel Dipeptidyl Peptidase 4 Inhibitor, on Adiposity with Increased Ppargc1a in White Adipose Tissue in Obese Mice.

Although dipeptidyl peptidase 4 (DPP4) is an adipokine known to positively correlate with adiposity, the effects of pharmacological DPP4 inhibition on body composition have not been fully understood. This study was aimed to assess the effects of DPP4 inhibitors on adiposity for the first time in the established obese mice model. The weight loss effects of multiple DPP4 inhibitors were compared after a 4 week treatment in diet-induced obese mice.

Hepatic role in an early glucose-lowering effect by a novel dipeptidyl peptidase 4 inhibitor, evogliptin, in a rodent model of type 2 diabetes.

Although multiple dipeptidyl peptidase 4 (DPP4) inhibitors have shown glucose-lowering effects by preserving pancreatic cells in high-fat diet (HFD)/streptozotocin (STZ)-induced diabetic mice, the hepatic role in regulation of glucose homeostasis by DPP4 inhibitors in HFD/STZ mice remains elusive. In herein study, parallel comparison of effects on the liver (expression of gluconeogenic genes and the linked signaling molecules) and pancreas (islet morphology and relative area of alpha or beta cells) in combination with glucose-lowering effects were made at the end of 2- and 10-week of evogliptin treatment in HFD/STZ mice. Significant control of hyperglycemia was observed from the second week and persisted during 10-week treatment of 0.
