Lâ € ™ exposure of mice aged at young blood has been shown to reverse the consequences of senilitaâ € ™ on learning, memory and neuronal function. The study andâ € ™ was published in Nature Medicine. This finding suggests that in mice factors in circulation, from the blood of young rodents, the effects could be reversed € ™ s aging on the brain. Previous studies have shown that factors from the blood of aged mice could affect cognitive function in young mice. Tony Wyss-Coray and colleagues from the University of California, San Francisco, found that repeated injections of blood from young mice of three months in rodent 18 months improved learning and memory. According to scientists, could behind these positive effects could be factors of blood heat sensitive and aged mice showed a regression of their damage linked EtAA allâ € ™ € ™ in the brain, structurally, at the molecular level and in terms of functional . These upgrades were mediated in part by € ™ protein activation Creb nellâ € ™ hippocampus.
