As tissues grow older, they become less…...

2+ week, 5+ day ago   (619+ words) A familiar cell-cycle protein may be helping aging cells broadcast inflammatory signals throughout the body, according to a new study published in Nature Aging. Researchers report that cyclin D1, or CCND1, and its partner enzyme CDK6 remain unusually active in senescent cells even…...

3+ week, 4+ day ago   (578+ words) Barcelona researchers have identified a molecular mechanism that may help explain why ageing skin develops a persistent, low-grade inflammatory state....

3+ week, 4+ day ago   (625+ words) Hematopoietic stem cells, the rare self-renewing cells that continually replenish blood and immune populations, do not simply “wear out” with age. They undergo a complex biological transformation that reshapes how they read DNA, respond to stress, interact with their surroundings…...
