Most K cells express PC1/3, which cleaves proGIP at Arg65, resulting in the biologically active GIP(142) (Ugleholdt et al., 2006) and stored in secretory granules (450 nm) (Meier et al., 2004a), GIP promotes nutrient-stimulated insulin secretion and increases glucagon secretion in the fasted state but not in patients with type 2 diabetes ( The physiological concentrations of the peptide hormones GIP, GLP-1, and GLP-2, are tightly controlled by the nutrient-sensing abilities of their respective enteroendocrine cells
