Mitochondrial Dysfunction as a Feature of Neurodegenerative Conditions

Increasing dysfunction of mitochondria, the power plants of the cell, is a feature of aging. It is also strongly connected to neurodegenerative conditions. The brain is an energy-hungry organ, and anything that interferes with the supply of nutrients and their processing to power cellular operations is going to cause issues. In this review paper, researchers discuss the link between mitochondrial dysfunction and neurodegeneration, and go on to note a few of the efforts underway to produce pharmacological treatments capable of restoring greater mitochondrial function in aged tissues. Sadly all too few of these treatments can outpace the beneficial effects of exercise on mitochondrial function. More and better approaches are needed, such as transplantation of functional mitochondria. The decline in mitochondrial function during aging and associated disorders like neurodegeneration has received much attention, and there are extensive efforts underway to develop pharmacological treatments that can restore the potential and integrity of these crucial organelles. A large number of pharmacological modulators, both natural and synthetic, are being studied for their ability to reduce mitochondrial stress by targeting different pathways, including mitochondrial OXPHOS, ROS homeostasis, and metabolic processes. Furthermore, several other pathways, such as mitochondrial biogenesis, dynamics, and degradation, are also considered in developing therapeutics against mitochondria-ass...
