Dipeptidyl peptidase 4 (DPP4), adipose inflammation, and insulin resistance: is it time to look to the hepatocyte?
Dipeptidyl peptidase 4 (DPP4), also known as adenosine deaminase binding protein or cluster of differentiation 26 (CD26), is a serine exopeptidase able to inactivate peptides composed of proline, hydroxyproline, or alanine as the penultimate residue. It has a strong capacity to act in various peptides and is also widely expressed in many specialized cell types, such as endothelial cells, macrophages, and adipocytes. On its physiological aspects, DPP4 inactivates the glucagon-like peptide-1 (GLP-1), an incretin secreted by the gastrointestinal tract (1). Based on the antidiabetic actions of this incretin, several DPP4 inhibitors (named as gliptins) were launched in the market and are being in use for the treatment of type 2 diabetes (1). It is noteworthy that DPP4 also inactivate some cytokines, chemokines, and neuropeptides involved in inflammation, immunity, and vascular function (2).
