Article Synopsis
  • Dynamin has been linked to regulating the amount and type of neurotransmitters released during exocytosis, but its mechanism is still not well understood.
  • Research using bovine adrenal chromaffin cells showed that inhibiting dynamin affects the formation and structure of the actin cytoskeleton, which is crucial for exocytosis.
  • The findings suggest that dynamin-2 works with F-actin to control the late stages of exocytosis, ultimately influencing hormone release to meet physiological needs.

Their incidence has increased steadily, in particular among the elderly, a high-risk population that is becoming an important segment of society. Neurodegenerative mechanisms underlie many ailments such as Parkinson's disease, Huntington's disease, Alzheimer's disease (AD) and Down syndrome (DS, trisomy 21).
