Hypothalamic stem cells control ageing speed partly through exosomal miRNAs. Nature, 2017; DOI: 10.1038/nature23282

Scientists at Albert Einstein College of Medicine have found that stem cells in the brain’s hypothalamus govern how fast aging occurs in the body. The finding, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan. The hypothalamus was known to regulate important processes including growth, development, reproduction and metabolism. In a 2013 Nature paper, Einstein researchers made the surprising finding that the hypothalamus also regulates aging throughout the body...

Neuroscientists have found a novel connection between the size of the choroid plexus in the brain and complex regional pain syndrome (CRPS), an unexpected finding, they say. ‘When studying magnetic resonance images of the brains of patients suffering from CRPS, we noticed that the choroid plexus was nearly 1/5 larger in patients than in healthy control subjects,’ says Postdoctoral Researcher Guangyu Zhou.

Located in the walls of the brain ventricles, the choroid ...
