Dipeptidyl Peptidase-4 Inhibitors Role(s) : Enhances insulin secretion by pancreatic -cells indirectly by prolonging the half-life or action of endogenous GLP-1
This creates a metabolic environment where weight loss becomes exceptionally difficult and fat storage, particularly visceral fat around the abdomen, becomes the default
The endogenous mechanism is triggered by the depletion of intracellular glutathione (GSH) and inactivation of GSH peroxidase 4 (GPX4) (Masaldan et al., 2019), cardiomyopathy (Timmers et al., 2020), atherosclerosis (Ouyang et al., 2021), liver injury (Tonnus et al., 2021), or related pathological cell death

Exercise-Induced GLP-1 Secretion Ninety minutes of exercise in mice induces a 2.5-fold increase in plasma active GLP-1, mediated by skeletal-muscle-derived IL-6, as shown by abolishing exercise-induced active GLP-1 levels in Il6 / mice and by treating wild-type mice with an antibody to IL-6 ( Gcg and Pcsk1 mRNA, but not plasma GLP-2 (ELISA) or DPP4 activity ( Gcg mRNA, chronic IL-6 treatment does not increase plasma GLP-2 levels suggesting a difference in GLP-1 and GLP-2 transcript or protein stability
