Samples were imaged with a Plan Apo 100 1.45 NA objective using a Nikon Ti-E inverted, widefield microscope equipped with a Nikon Perfect Focus system with a Piezo Z drive motor, Andor Zyla sCMOS camera, and NIS Elements (v4.5)

Several in vitro and in vivo results have expanded the role of these molecules from potentiating glucose-stimulated insulin secretion to promoting -cell survival under different stressful environments by favoring proliferation, neogenesis and resistance to apoptosis ( via secretion of IGF-2 from the same cells ( In agreement with experimental studies, GLP-1 analogues, particularly liraglutide, sustain the maintenance of -cell function in obese individuals with early T2D, and these effects are presumably independent of weight loss ( Further, experimental data suggest that the pro-survival action of GLP-1RAs may also be mediated by the Akt-dependent stimulation of the mTORC1/S6K1 pathway, the activation of which is dependent upon the IGF-1R, as observed in rodent islet cells ( in vitro , exendin-4 lost the ability to activate this pathway, suggesting that GLP-1 analogues may restore -cell proliferation via autocrine or paracrine activation of IGF-1R ( In concert, these results define a new scenario of action for incretin-based therapy that may involve the adipo-insular axis, linking the weight lowering competence with the sustained protection of -cells from diabetogenic stressors
