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 (T2DM) which may lead to bronchial hyperersponsiveness (BHR). Since glucagon-like peptide 1 regulates glucose homeostasis, we pharmacologically investigated the influence of the glucagon-like peptide 1 receptor (GLP1-R) agonist exendin-4 on the bronchial 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 asthmatic and diabetic patients, 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...

METHODOLOGY: Collection of clinical data before the commencement of treatment and in the following 12 months. The following data was collected for all patients: demographic data, time elapsed from diagnosis, body weight, BMI, HbA1c, systolic and diastolic blood pressure, total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides...

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...

Systematic SAR optimization of the GPR119 agonist lead 1, derived from an internal HTS campaign, led to compound 29. Compound 29 displays significantly improved in vitro activity and oral exposure, leading to GLP1 elevation in acutely dosed mice and reduced glucose excursion in an OGTT study in rats at doses ⩾10 mg/kg.

Obesity is now a major international health concern. It is increasingly common in young women with reproductive, metabolic and psychological health impacts. Reproductive health impacts are often poorly appreciated and include polycystic ovary syndrome (PCOS), infertility and pregnancy complications. PCOS is the most common endocrine condition in women and is underpinned by hormonal disturbances including insulin resistance and hyperandrogenism. Obesity exacerbates hormonal and clinical features of PCOS and women with PCOS appear at higher risk of obesity, with multiple underlying mechanisms linking the conditions...

In recent years the treatment focus for type 2 diabetes has shifted to prevention by lifestyle change and to more aggressive reduction of blood sugars during the early stage of treatment. Weight reduction is an important goal for many people with type 2 diabetes. Bariatric surgery is no longer considered a last resort treatment. Glucagon-like peptide-1 agonists given by injection are emerging as a useful treatment since they not only lower blood sugar but are associated with a modest weight reduction. The role of the oral dipeptidyl peptidase 4 inhibitors is emerging as second line treatment ahead of sulphonylureas due to a possible beneficial effect on the beta cell and weight neutrality...
