Narrative review reveals how impaired mitochondrial fusion and fission drive insulin resistance in older adults, highlighting dynamics as a potential therapeutic target.

Key Points

To review the molecular mechanisms of mitochondrial fusion and fission dysfunction and assess their causal role and therapeutic relevance in age-associated type 2 diabetes.
Synthesized molecular evidence on primary fusion proteins (MFN1, MFN2, OPA1) and fission mediators (FIS1, DRP1) in metabolic regulation.
Evaluated pathophysiological pathways connecting mitochondrial network fragmentation to cellular energy failure and insulin resistance in aging populations.
Defects in fusion and fission machinery compromise mitochondrial DNA integrity, accelerate apoptosis, and trigger excessive reactive oxygen species release.
Mitochondrial network fragmentation directly contributes to pancreatic beta-cell failure and peripheral insulin resistance, driving disease in older populations where men aged 65 and older account for 59% of cases.
