An international team of scientists has described a mechanism that allows cells to renew and resist aging. The research results are published in the FASEB Journal.
According to published data, cells in the human body are renewed by releasing damaged mitochondria. However, in older people, the process of mitochondrial renewal slows down, which leads to loss of muscle mass and the appearance of excess weight. Scientists have presented the concept of special fluorescent labels that study mitochondria in cells and identify damaged ones. With this information, you can start cell renewal medically.
Researchers have noticed that pharmaceutical companies have long been working on a drug that stimulates the destruction of spent mitochondria and would reveal the secret to staying young. For this process, the drug must activate the molecules of the energy sensor, AMP-activated protein kinase. Scientists believe that their discovery will help accelerate the development of such a drug. The study notes that regular exercise can help accelerate cell turnover in both young and old people.
Earlier, American scientists stated that premature aging is associated with an increased amount of carbohydrates consumed. Studies have shown that adhering to a low-carb diet that includes meat and fish with salad can increase brain activity.
In December 2019, the medical journal Nature Medicine named three stages of human aging. The first stage begins at 34, the second at 60, and the third at 78. This division is explained by shifts in the proteins of the liquid part of the blood, which are characteristic only for a certain age.
