Effects of the glucagon-like 1 receptor agonist exendin-4 on activated gut intraepithelial lymphocytes

Project description:Gut intraepithelial lymphocytes (IELs) are one of the few immune cell populations in the body that expresses glucagon-like 1 receptors (GLP-1R). To test the potential effects of GLP-1 on gut IEL function, we performed bulk RNA-seq on gut IELs isolated from C57BL/6J mice treated with anti-CD3 and with or without exendin-4 for 3 hours.

BI 456906: a dual glucagon-like peptide-1/glucagon agonist promoting bodyweight reduction

Project description:Glucagon and glucagon-like peptide-1 (GLP-1) are hormones involved in energy homeostasis. GLP-1 receptor (GLP-1R) agonism reduces food intake and delays gastric emptying, and glucagon receptor (GCGR) agonism increases energy expenditure by thermogenesis. BI 456906 is a subcutaneous, once-weekly injectable dual GLP-1R/GCGR agonist in development for the treatment of obesity or non-alcoholic steatohepatitis. Here we show that BI 456906 is a potent dual agonist with an extended half-life in human plasma. Key GLP-1R-mediated mechanisms of reduced food intake, delayed gastric emptying and improved glucose tolerance were confirmed in GLP-1R knockout mice. GCGR activity was confirmed by reduced plasma amino acids, increased hepatic expression of nicotinamide N-methyltransferase and increased energy expenditure. BI 456906 produced greater bodyweight reductions than maximally efficacious semaglutide doses and modulated gene expression, including genes involved in amino acid metabolism. BI 456906 is a potent dual agonist that produces bodyweight-lowering effects through both GLP-1R and GCGR agonism.

Comparison of gamma delta intraepithelial lymphocytes from DSS-treated and untreated colon

Project description:gamma delta intraepithelial lymphocytes were isolated from the colons of DSS-treated and untreated mice. Total RNAs were isolated and compared by Affymetrix DNA microarray. Duplicate comparisons were made between DSS-treated and untreated gamma delta intraepithelial lymphocytes.

Expression data from mouse small intestinal γδ intraepithelial lymphocytes

Project description:The mammalian gastrointestinal tract harbors thousands of bacterial species that include symbionts as well as potential pathogens. The immune responses that limit access of these bacteria to underlying tissue remain poorly defined. In this study, we used microarrays to uncover the transcriptional responses that occur in small intestinal γδ intraepithelial lymphocytes following bacterial challenge. γδ intraepithelial lymphocytes (γδ IEL) were isolated by flow cytometry from the small intestines of germ-free mice, or from age- and sex-matched conventionally-raised counterparts. We extracted RNAs from these purified γδ IEL for analysis on Affymetrix DNA microarrays. The mice were all >8 weeks in age, and each sample represents a pool of RNAs from 5-8 mice.

Dietary protein defends lean mass and maintains metabolic benefits of glucagon receptor agonist G108 in mice

Project description:Glucagon has long been proposed as a component of multi-agonist obesity therapeutics due to its ability to induce energy expenditure and cause weight loss. However, chronic glucagon-receptor agonism has been associated with a reduction in circulating amino acids and loss of lean mass. Importantly, it is currently not known whether the metabolic benefits of glucagon can be maintained in contexts that permit the defence of lean mass.

Chronic treatment with glucagon-like peptide-1/glucagon receptor co-agonist causes weight-loss independent improvements in hepatic steatosis

Project description:Co-agonists at the glucagon-like peptide-1/glucagon receptors (GLP1R/GCGR) show promise as treatments for metabolic dysfunction-associated steatotic liver disease (MASLD). Unlike GLP1, glucagon directly acts on the liver to reduce fat content. To date most metabolic studies have looked at heavily GLP1R-biased co-agonists and have not distinguished weight-loss versus weight loss-independent effects. We demonstrate that 24 days’ treatment with Dicretin, a GLP1/GCGR co-agonist with high potency at the GCGR, in mice with hepatic steatosis secondary to diet-induced obesity leads to superior reduction of hepatic lipid content when compared to Semaglutide or equivalent weight loss by calorie restriction. Hepatic transcriptomic and metabolomic profiling demonstrated many changes that were unique to Dicretin-treated mice: some known targets of glucagon signalling and others with as yet unclear physiological significance. Our study supports the development of GLP1/GCGR co-agonists for treatment of MASLD and related conditions.
