Under hyperglycemic conditions, RGCs exhibit significant mitochondrial impairment, including cristae dissolution, swelling, vacuolar degeneration, elevated reactive oxygen species (ROS) production, and diminished mitochondrial membrane potential (MMP) [68, 69]
Therefore, DPPIV inhibitors might promote glucoregulation in part because of resulting elevated levels of PYY 1-36 , albeit with associated losses in food intake and body weight reduction
But it aligns with the general principle that slower escalation produces fewer side effects across all categories
This confirms that the observed metabolic reprogramming was dependent on chronic activation of GLP-1R signalling and independent of its acute stimulation of insulin secretion, which may result in autocrine insulin signalling
ROS also play important roles in the activation and regulation of innate and adaptive immunity, including respiratory bursts and inflammasome activation 18,19
Studies show that most people regain weight when they stop the medication
