    "body_text": "University of Kentucky researchers temporarily depleted about 87 percent of microglia for 14 days in a mouse model of Alzheimer's disease. The animals recovered more than two hours of sleep per day, chiefly non-REM sleep, even though amyloid plaque burden did not change. The result points toward immune signaling as a contributor to disrupted sleep in this model. It is a short preclinical experiment and does not establish a safe or effective treatment for people.",
