ABSTRACT
Diabetes is a chronic metabolic disorder with rising global prevalence, particularly in developed and high-income regions. Central to its pathogenesis is the dysfunction of pancreatic β-cells, alongside impaired glucose and lipid metabolism in peripheral insulin-responsive tissues. Exosomes are nano-sized extracellular vesicles essential for intercellular communication and have emerged as pivotal regulators of metabolic homeostasis. Secreted by virtually all cell types, exosomes encapsulate bioactive cargo that reflects their cellular origin and physiological state, thereby exerting diverse functional effects. Recent evidence highlights the role of exosomes derived from the liver, gut, adipose tissue, skeletal muscle, and mesenchymal stem cells in modulating β-cell proliferation, insulin secretion, and survival. In peripheral tissues exosomes also influence insulin sensitivity by regulating glucose and lipid metabolism, ultimately shaping β-cell responses under hyperglycemic conditions. A more comprehensive understanding of exosome-mediated crosstalk between metabolic organs and pancreatic β-cells could pave the way for the development of exosome-based diagnostic tools and therapeutic strategies aimed at improving early detection, prevention, and treatment of the diabetes.
