Patients with kidney disease have a significantly increased cardiovascular morbidity and mortality. Especially diabetics have an increased risk to develop renal insufficiency and cardiovascular events. Two recent studies show that the SGLT2 inhibitor Empagliflozin and the GLP1 agonist Liraglutid are able to lower the cardiovascular risk of type2 diabetics with renal insufficiency. Recent observations suggest that bradycardia and asystole are main triggers for sudden cardiac death in patients with chronic kidney disease...

Glucagon-like peptide-1 (GLP1) has many anti-diabetic actions and also increases energy expenditure in vivo. Since skeletal muscle is a major organ controlling energy metabolism, we investigated whether GLP1 can affect energy metabolism in muscle. We found that treatment of differentiated C2C12 cells with Exendin-4 (Ex-4), a GLP1 receptor agonist, reduced oleate:palmitate-induced lipid accumulation and triglyceride content compared with cells without Ex-4 treatment. When we examined the oxygen consumption rate (OCR), not only the basal OCR but also the OCR induced by oleate:palmitate addition was significantly increased in Ex-4-treated differentiated C2C12 cells, and this was inhibited by Exendin-9, a GLP1 receptor antagonist...

Type 2 diabetic (T2D) patients often develop early cognitive and sensorimotor impairments. The pathophysiological mechanisms behind these problems are largely unknown. Recent studies demonstrate that dysfunctional γ-aminobutyric acid (GABAergic) neurons are involved in age-related cognitive decline. We hypothesized that similar, but earlier dysfunction is taking place under T2D in the neocortex and striatum (two brain areas important for cognition and sensorimotor functions). We also hypothesized that the T2D-induced effects are pharmacologically reversible by anti-diabetic drugs targeting the glucagon-like peptide-1 receptor (GLP-1R)...

UNLABELLED: Excessive hepatic glucose production resulting from dysregulated glucagon secretion associated with inappropriate fasting and postprandial hyperglucagonemia is common feature in type 2 diabetes (DM2T). The effects of some currently widely used anti-diabetic agents, especially concerning metformin, GLP1 agonists and inhibitors of DPP4, comprise partial supression of glucagon secretion and/or action. Complete supression of glucagon action is recently widely investigated in experiments, and also results of phase 1 and 2 of the clinical trials are available...

Adipose-resident invariant natural killer T (iNKT) cells are key players in metabolic regulation. iNKT cells are innate lipid sensors, and their activation, using their prototypic ligand α-galactosylceramide (αGalCer), induces weight loss and restores glycemic control in obesity. Here, iNKT activation induced fibroblast growth factor 21 (FGF21) production and thermogenic browning of white fat. Complete metabolic analysis revealed that iNKT cell activation induced increased body temperature, V02, VC02, and fatty acid oxidation, without affecting food intake or activity...

Beside the influence of nutritional habits and reduced physical activity, metabolic syndrome is associated with alterations in the structure of gut microbiota influencing the inflammatory immune responses. Gut microbiota and microbial metabolic activities are known to affect the lipid and glucose metabolism, satiety and chronic low-grade inflammation in the metabolic syndrome. The aim of the study was to identify genera or even species affecting host metabolism in obesity and type 2 diabetes beside the commonly used indicator: Firmicutes/Bacteroidetes ratio...

Asthma is associated with several comorbidities, such as type 2 diabetes mellitus, which may lead to bronchial hyperresponsiveness (BHR). Because glucagon-like peptide (GLP) 1 regulates glucose homeostasis, we pharmacologically investigated the influence of the GLP1 receptor (GLP1-R) agonist, exendin-4, on BHR induced in human isolated airways. The effect of exendin-4 was assessed in human isolated airways undergoing overnight passive sensitization and high-glucose stimulation, two conditions mimicking ex vivo the BHR typical of patients with asthma and diabetes, respectively...

AIMS: Diabetes treatments aim at preventing undesirable metabolic effects of hyperglycemia and at preventing/reducing tissue damage, including cardiovascular (CV) events. For approval, novel diabetes drugs undergo early systematic investigation to assess CV safety. This review provides an updated analysis of the results of recent studies examining novel diabetes medications and CV outcomes. DATA SYNTHESIS: The new regulatory guidelines enforce adjudication of all CV events when testing novel diabetes drugs...

There is limited comparative effectiveness evidence to guide approaches to managing diabetes in individuals failing metformin monotherapy. Our aim was to compare the incidence of all-cause mortality and major adverse cardiovascular events (MACEs) among new metformin monotherapy users initiating a dipeptidyl-peptidase-4 inhibitor (DPP4i), glucagon-like peptide-1 receptor agonist (GLP-1RA), sulfonylurea (SU), thiazolidinedione, or insulin.We conducted a cohort study using the UK-based Clinical Practice Research Datalink...

Adding glucagon-like peptide-1 receptor agonists (GLP-1 RAs) to basal insulin regimens has become a guideline-recommended treatment option for uncontrolled type 2 diabetes. However, limited data exist to support the use of GLP-1 RAs with insulin regimens, including bolus insulin in patients with type 2 diabetes. The primary objectives of this review were to identify if the combination of a GLP-1 RA and an insulin regimen containing bolus insulin resulted in improvements in HbA1c , weight loss, reduction in insulin doses, and to evaluate the side effect profile of this combination in terms of nausea and hypoglycemia risk...

The two incretin hormones, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP1), were discovered 45 and 30 years ago. Initially, only their insulinotropic effect on pancreatic β cells was known. Over the years, physiological and pharmacological effects of GIP and GLP1 in numerous extrapancreatic tissues were discovered which partially overlap, but may also be specific for GIP or GLP1 in certain target tissues. While the insulinotropic effect of GIP was found to be blunted in patients with type 2 diabetes, the function of GLP1 is preserved and GLP1 receptor agonists and dipeptidyl-peptidase 4 (DPP4) inhibitors, which prolong the half-life of incretins, are widely used in diabetes therapy...

Glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1 RAs) are useful tools for treating type 2 diabetes mellitus. In their recent position statement, the American Diabetes Association and European Association for the Study of Diabetes recommend GLP1-RAs as add-on to metformin when therapeutic goals are not achieved with monotherapy, particularly for patients who wish to avoid weight gain or hypoglycemia. GLP1-RAs differ substantially in their duration of action, frequency of administration and clinical profile...

Glucagon-like peptide-1 (GLP1) is a 30-amino acid peptide hormone activating the GLP1 receptor (GLP1R), a class B G-protein coupled receptor (GPCR), and is considered to be effective for treating diabetes and other metabolic diseases. Phage display is the first innovative technology in order to prepare and screen a large polypeptide library including GLP1R agonists, but this methodology is not as effective in discovering functional peptides such as activators for GPCRs. Here, we report a novel functional screening system for GPCR-acting peptides, which integrates a yeast peptide secretion system into a biological detection system with GPCR-producing mammalian cells...

The prevalence of obesity continues to be increasing in all age groups in most countries of the European Union (EU). Many obese people have a history of several successful weight losses, but very few are able to maintain the weight loss over a longer period of time. Initiation of the GLP1 RA administration during weight loss maintenance would inhibit weight loss-induced increases in soluble leptin receptor plasma concentrations resulting in higher level of free leptin thereby preventing weight regain. In contrast initiation of insulin treatment in type 2 diabetes patients is frequently accompanied with weight gain...
