Lipid metabolism and lipid signals in aging and longevity

Dev Cell. 2021 May 17;56(10):1394-1407. doi: 10.1016/j.devcel.2021.03.034. Epub 2021 Apr 22.


Lipids play crucial roles in regulating aging and longevity. In the past few decades, a series of genetic pathways have been discovered to regulate lifespan in model organisms. Interestingly, many of these regulatory pathways are linked to lipid metabolism and lipid signaling. Lipid metabolic enzymes undergo significant changes during aging and are regulated by different longevity pathways. Lipids also actively modulate lifespan and health span as signaling molecules. In this review, we summarize recent insights into the roles of lipid metabolism and lipid signaling in aging and discuss lipid-related interventions in promoting longevity.

Keywords: aging; lipid metabolism; lipid signals; longevity.
