Researchers here consider dysregulation of lipid metabolism at the cellular level as an aspect of aging that causes downstream issues. Like many manifestations of aging observed in cells in aged tissues, why this happens is a matter for debate, setting aside situations such as the environment of a fatty liver or atherosclerotic plaque in which there is a localized excess of lipids to explain the overload inside cells. In a number of neurodegenerative conditions, the presence of cells loaded with lipid droplets is a prominent feature. It remains to be seen as to whether new classes of therapy under development, capable of clearing lipids in a selective manner, will prove to be useful in that context.
