. We also now recognize links between aberrant lysosomal function and several diseases, including lysosomal storage diseases (e.g., Tay-Sachs disease) and neurodegenerative disorders (e.g., Parkinson's disease), and also with aging (1). On page 83 of this issue, Folick et al. (3) indicate how lysosomes play a role in the latter—by deploying a lipid molecule to the nucleus, whose impact on gene expression extends life span in an animal model (the nematode Caenorhabditis elegans). The study not only uncovers a lysosome-to-nucleus signaling pathway but also highlights the potential of lipids in mediating long-range physiological effects.
