microdosing glp 1 for anxiety GLP-1 is popular, but there's little evidence it works Exploring glucagon-like peptide-1 receptor agonists

These studies reveal that islet-derived proglucagon products are the predominant ligand for beta-cell glucagon-like peptide 1 receptor (GLP-1R) activation and are necessary for the glucoregulatory improvements of DPP-IV inhibitors (DPP-IVi) and vertical sleeve gastrectomy (VSG) ( In further characterizing this paracrine effect, the field has employed several different models of selective inhibition of proglucagon expression to more directly investigate the relative contributions of gut- versus islet-derived proglucagon products to glucose homeostasis ( Figure 2 )

While many antidepressant medications come with a risk of weight gain, bupropion offers an option to treat depression without this side effect

Characterizations of this state of metabolic crisis have distinguished low fuel (ischemic) states from conditions in which metabolic substrates are available but not effectively utilized (mitochondrial dysfunction)

It may modulate TCA cycle activity via secondary messengers like cAMP, though further validation is needed (263)
