Mitochondrial defects in pancreatic beta
Abstract Mitochondria malfunction is linked to the development of β- cell failure and a variety of neurodegenerative disorders. Pancreatic β- cells are normally configured to detect glucose and other food secretagogues in order to adjust insulin exocytosis and maintain glucose homeostasis.
Cellular bioenergetics and mitochondrial dynamics are crucial for the secretion of insulin by pancreatic beta cells in response to elevated levels of blood glucose. To elucidate the interactions ...
Mitochondrial Homeostasis in Pancreatic Cell Function
Mitochondrial homeostasis is essential for pancreatic β cell function, and its disruption underlies diabetes pathogenesis. Chronic hyperglycemia, lipotoxicity, and inflammation impair mitochondrial quality control (MQC), leading to β cell dysfunction , oxidative stress, and apoptosis. Mitochondria -organelle interactions, particularly with the endoplasmic reticulum (ER), lysosomes, and Golgi ...
As we can see from the illustration, Cannabinoids And Mitochondria In Pancreatic Beta Cell Dysfunction has many fascinating aspects to explore.
In pancreatic β cells , mitochondria play a central role in coupling glucose metabolism to insulin exocytosis, thereby ensuring strict control of glucose-stimulated insulin secretion. Defects in mitochondrial function impair this metabolic coupling, and ultimately promote apoptosis and β cell death. Various factors have been identified that may contribute to mitochondrial dysfunction . In this ...
Useful Notes on Cannabinoids And Mitochondria In Pancreatic Beta Cell Dysfunction
Mitochondria , as essential organelles that integrate energy metabolism and intracellular signaling, have recently gained increasing attention in the study of pancreatic β- cell dysfunction in type 2 diabetes mellitus (T2DM). Programmed death of β- cells is recognized as a mechanism contributing to both disease progression and remission, primarily by impairing insulin secretion and disrupting ...
The present review examined the potential factors underlying mitochondrial dysfunction and their association with islet β- cell failure, which may offer novel insights regarding future strategies ...
Mitochondrial bioenergetics, metabolism, and beyond in ...
The pancreatic β- cell secretes insulin in response to elevated plasma glucose. This review applies an external bioenergetic critique to the central processes of glucose-stimulated insulin secretion, including glycolytic and mitochondrial metabolism, the cytosolic adenine nucleotide pool, and its interaction with plasma membrane ion channels. The control mechanisms responsible for the unique ...
The presence and activity of the ECS in pancreatic islets have been reported in different models: cell lines, primary culture of intact islets or dispersed cells ; in histological slides of pancreas obtained from rats, mice, and humans, under healthy, obesity of diabetic conditions. 33-45 Gene expression and localization of cannabinoid ...
ABSTRACT The following review focuses on the scientific studies related to the role of endocannabinoid system (ECS) in pancreatic islet physiology and dysfunction . Different natural or synthetic agonists and antagonists have been suggested as an alternative treatment for diabetes, obesity and metabolic syndrome. Therapeutic use of Cannabis led to the discovery and characterization of the ECS ...
