A cell can aging the brain

According to a new British study, brain cells also undergo the same aging process as skin cells: an aging cell will affect many of its 'neighbors' .

British researchers found that aging neurons in the rat brain produce many substances, including free radicals and other molecules, which can promote inflammation and change DNA, causing risk of damage to nearby cells.

Previously, scientists have determined that skin cells also produce similar substances when they age and become 'rotting apples' , which can affect cells near them. . However, neurons are thought to be aging in a completely different way.

Skin cells, such as fibroblasts - participate in wound healing, still maintaining their ability to divide. Meanwhile, most neurons in adults cannot be divided.

Live Science quoted researcher Thomas von Zglinicki, professor of geriatrics at Newcastle University, saying: 'This study provides us with a new idea of ​​the extent of the spread from the area. the first affected area to the whole brain '.

Mr. von Zglinicki and his colleagues asserted that the findings could open new ways to treat brain disorders such as dementia, motor nerves or hearing loss for old age. However, they emphasized that research in mice does not always coincide with human studies.

'We will now have to find out if the mechanism of detection in rat brains is similar to that of brain aging and cognitive loss in humans,' von Zglinicki added.

If research results confirm similarities in humans, scientists may have opened a shortcut to improving understanding of brain aging.
