Scientists from the University of California in San Francisco have found that the "Sleep" x Chromosom can awaken with older females, which can activate up to 20 genes that help strengthen the brain connections. The results of the work were published in the magazine of Science Advances.
One of such genes, PLP1, helps Melin's design, a neuron protective membrane that is important for effective signal transmission between brain cells. Studies have shown that there is more PLP1 in the hippocampus of the elderly female mice, which can explain them greater resistance to cognitive disorders compared to males.
Scientists say that the activation of "Sleeping" x Chromosome is taking place at the age of 65 in the age of 65. This process not only helps to maintain the activity of the brain, but also helps to maintain memory and learning among elderly people.
To check the hypothesis, scientists have artificially activated PLP1 in the hippocamp of the old rodents of both sexes. The results showed that additional PLP1 improves cognitive work, regardless of gender.
Scientists are currently investigating whether this process can take place in people. The analysis of the elderly women and men's brain tissue confirmed that women had a significantly higher level of PLP1, supporting the idea that the second X Chromosoma plays an important role in maintaining brain health during old age.
