The results paved the way for liraglutide, branded as Saxenda, to be approved in the US as a once-a-day subcutaneous injection in December 2014 and in Europe in 2015 for the treatment of chronic weight management combined with a reduced calorie diet and increased physical exercise (Molteni, Chen)
Doctors noticed that as a side effect of taking this medication for months or years, patients skin tones became significantly lighter

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
