Abstract
En 中文
A new study reveals that aging hematopoietic stem cells trigger a form of innate immune memory, known as trained immunity, that fuels the chronic low-grade inflammation that underlies age-related physiological decline. SIRT3, a mitochondrial deacetylase whose expression wanes with age, emerges as a key molecular brake on this process.
