Insulin affects the recycling of cellular power plants

In nerve cells, insulin facilitates the elimination of defective mitochondria when energy is available. However, during energy scarcity or disrupted insulin signaling, mitochondrial recycling is reduced, allowing potentially damaged power plants to continue operating. This process affects ageing processes and neurological diseases.
