By recycling itself, glutathione helps support cellular protection, mitochondrial function, detoxification, and overall antioxidant defence throughout the body

However, all these treatments are symptomatic and cannot prevent or reverse AD pathology ( Figure 1 ) ( Figure 1 Biological characteristics of GLP-1 In the 1980s, a new glucagon-like peptide, produced from proglucagon cleavage, was discovered to stimulate insulin secretion ( GLP-1, a 36-amino acid peptide, is produced in enteroendocrine L-cells of the distal small bowel and colon ( The effect of GLP-1 depends on blood glucose levels since it can only potentiate glucose-stimulated insulin secretion from islet beta cells in the hyperglycemic state rather than in the normal blood glucose state ( Tissue distribution of GLP-1R GLP-1 mediates its effects by binding to its receptor, the GLP-1R, which is a sevenfold transmembrane G-coupled receptor that increases levels of cAMP by activating adenylate cyclase ( In the peripheral system, GLP-1R mediates the actions of GLP-1 via the incretin axis, in which stimulation of the GLP-1R with GLP-1 primarily triggers insulin release from islet cells in a glucose-dependent manner and inhibits glucagon secretion from islet cells ( s coupling pathway (114)
