It is believed to reduce cardiovascular mortality by improving cardiac energy metabolism, reducing cardiac preload and afterload, and possibly through direct effects on cardiac and vascular tissues
83 However, within the tumor niche, cancer cells, MDSCs, TAMs, suppressive DCs, and cancer-associated fibroblasts, among other cell types, exhibit upregulated expression of indoleamine 2,3-dioxygenase (IDO), which metabolizes tryptophan into suppressive kynurenine to promote Tregs and suppress CD8 + T cell function
In preclinical and ex vivo models, GLP-1R agonism has been linked to augmented glucose-dependent insulin secretion, suppressed glucagon release from pancreatic alpha cells, and delayed gastric emptying
At least two of the five peptides were detected in most sawfly species, whereas none in any outgroup taxon
