A Q&A with Thomas A. Rando, M.D., Ph.D. on Young Blood, Biomarkers, and Aging
Researcher Thomas Rando, from Stanford University, talks about efforts to increase the number of healthy years we live.
Young, resting neural stem cells have large protein clumps often associated with neurodegeneration. As stem cells age, the aggregates inhibit their ability to make new neurons, Stanford researchers say.
Old blood can prematurely age the brains of young mice, and scientists may now be closer to understanding how. A protein located in the cells that form a barrier between the brain and blood could be partly to blame, experiments on mice suggest.
