Abstract
Diabetic cardiomyopathy (DCM) is a cardiac disorder characterized by structural and functional impairments independent of coronary artery disease. Membrane microdomains, including lipid rafts and caveolae, play a crucial role in cardiac signaling, insulin receptor trafficking, and ion channel regulation. In diabetes, disrupting these microdomains leads to impaired insulin signaling, oxidative stress, and mitochondrial dysfunction, exacerbating cardiac pathology. This review explores the role of caveolins and lipid rafts in DCM and how their dysfunction contributes to disease progression. We highlight how therapeutics used to manage diabetic patients may impact microdomain integrity. Future research should focus on targeting membrane microdomains for novel treatments.
期刊介绍：
The American Journal of Physiology-Heart and Circulatory Physiology publishes original investigations, reviews and perspectives on the physiology of the heart, vasculature, and lymphatics. These articles include experimental and theoretical studies of cardiovascular function at all levels of organization ranging from the intact and integrative animal and organ function to the cellular, subcellular, and molecular levels. The journal embraces new descriptions of these functions and their control systems, as well as their basis in biochemistry, biophysics, genetics, and cell biology. Preference is given to research that provides significant new mechanistic physiological insights that determine the performance of the normal and abnormal heart and circulation.
