  "summary": "Brain-resident immune cells that have reached an old-age state called \"senescence\" secrete a protein that causes dysfunction in other brain cells, according to a study led by investigators at Weill Cornell Medicine. The discovery sheds light on how aging impairs memory and cognition and makes the brain vulnerable to neurodegenerative disorders.",
