A possible explanation for this may be that, even though in diabetic individuals an increase in CD26 levels has been found to correlate with insulin resistance, CD26 is a glycoprotein with several functions, among which is the regulation of the activity of chemokines and cytokines, molecules that play an important role in the development of atherosclerosis and cardiovascular disease (Ngetich et al., 2021), and this was not evaluated in this work. This evidence concerns the gene DPP4 and atherosclerosis.
