Although brain structure changes throughout life and is linked to both aging and neurodegenerative conditions such as Parkinson\u2019s and Alzheimer\u2019s diseases, the underlying molecular processes involved\u2014including cellular senescence\u2014are not defined. Cellular senescence is commonly defined as a state characterized by permanent cell cycle arrest in the absence of cell death, in which cells have altered function. While cellular senescence has been implicated in aging and disease, its role in shaping human brain structure\u2014both during development and aging\u2014has remained unclear.<\/p>\n<p>\u201cThis is the first study to directly link senescence-related molecular networks in living human brain tissue to measurable differences in brain structure within the same individuals,\u201d said Noam Beckmann, PhD, Director of Data Sciences and founding member for the Mount Sinai Clinical Intelligence Center, Assistant Professor of Artificial Intelligence and Human Health, and co-senior author of the paper. \u201cBy identifying molecular pathways that are engaged in both brain structure development and aging, our work highlights senescence as a fundamental biological feature of brain aging and neurodegenerative disease and helps prioritize targets for future experimental research aimed at protecting brain health.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at the Icahn School of Medicine at Mount Sinai have characterized how cellular senescence\u2014a biological process in which aging cells change how they function\u2014is associated with human brain structure in both development and late life.
