It's therefore of crucial importance to keep diabetic patients under proper management not only to control short term complications and to prevent liver and cardio-renal-metabolic complications, but also to reduce the risk of a potentially severe course and limit adverse outcomes due to COVID-19 [3] [4] [5] [6] [7] . Several authors have emphasized the importance of novel anti-diabetic agents during this pandemic, such as incretin-based therapies, for patients with type-2 diabetes (T2DM) [8] [9] [10] . Dipeptidyl peptidase-4 (DPP4)-inhibitors and glucagon-like peptide 1 receptor agonists (GLP1-RAs) have the ability to support near-normoglycemic glucose control without increasing the risk for hypoglycemic episodes and most of GLP1-RAs have demonstrated significant cardio-renal benefits that help the prevention of such complications and prolonging patients' healthy lives [11, 12] . This editorial is part of the special issue entitled "The role of incretin hormones and incretin-based glucose-lowering medications", containing ten publications from distinguished international experts in the field, and edited by the authors of the present article. Firstly, JJ Holst reviewed available evidence on the role of GIP and GLP-1 in the incretin system in healthy humans, concluding that both hormones act to improve glucose tolerance and that their effects are additive: GIP seems to be quantitatively the most important, particularly regarding insulin secretion, while GLP-1 action seems to be mainly displayed via inhibition of glucagon secretion [13] . suggest with respect to GLP-1 receptor agonists and DPP-4 inhibitors [22] .
