Using a mouse model of human aging and disease, NIAID scientists and Stanford University colleagues have shown that immune systems of aged laboratory mice can be made more youthful and effective at fighting disease by depleting a subset of haematopoietic stem cells (HSCs). The researchers think the method they developed may have potential for rejuvenating immunity in elderly people and are pursuing further study. Their findings are published in Nature.
