Low Dose Continuous Rapamycin Favorably Alters the Aging Immune System (opens in new tab)

Rapamycin is an immunosuppressant long used in transplant medicine at relatively high doses. At lower doses, it slows aging and extends life in animal studies by mimicking some of the beneficial metabolic reactions to calorie restriction, such as increased autophagy. A fair number of people use rapamycin with the hopes of achieving the same outcome, though the human data for this use case and dosage remains sparse. Normally rapamyin is taken once a week, but here researchers mix it in with th...
