Abstract

Background: The hormone melatonin (MEL), primarily acknowledged for its role in regulating circadian rhythms, has demonstrated itself to be a complicated molecule with significant implications for vascular physiology. Melatonin exerts extensive physiological effects directly via the MEL receptor type 1 (MT₁R) and the MEL receptor type 2 (MT₂R), as well as indirectly through the improvement of antioxidant vascular tone.

Objective: This review aims to analyse the intricate relationships between MEL and the renin-angiotensin system (RAS) in the vascular attenuation of non-diabetic (non-DM) and diabetic (DM) contexts. Alterations in the expression of RAS components and their dysregulation are prevalent in diabetes. Melatonin exhibits vasoprotective advantages in non-diabetic conditions. In the context of DM, vascular problrms such as vascular endothelial dysfunction (VED), hypertension, and atherosclerosis result from the dysregulation of MEL-RAS interactions. Comprehending the actions of MEL on RAS components in diabetes vasculature is essential for formulating tailored pharmaceutical therapy methods.

Conclusion: This review consolidates existing knowledge regarding the vascular effects of MEL in relation to RAS activation, emphasising its potential role as a modulating factor for angiotensin 1-8 (Ang 1-8), angiotensin-converting enzyme 2 (ACE₂), and angiotensin 1-7 (Ang 1-7) in the management of vascular complications associated with DM.

期刊介绍： Acta Diabetologica is a journal that publishes reports of experimental and clinical research on diabetes mellitus and related metabolic diseases. Original contributions on biochemical, physiological, pathophysiological and clinical aspects of research on diabetes and metabolic diseases are welcome. Reports are published in the form of original articles, short communications and letters to the editor. Invited reviews and editorials are also published. A Methodology forum, which publishes contributions on methodological aspects of diabetes in vivo and in vitro, is also available. The Editor-in-chief will be pleased to consider articles describing new techniques (e.g., new transplantation methods, metabolic models), of innovative importance in the field of diabetes/metabolism. Finally, workshop reports are also welcome in Acta Diabetologica.
