What ages fastest in the human body
Research shows that aging is uneven: blood vessels begin to age faster than other tissues after about age 50, while the adrenal glands start aging as early as 30. Scientists analyzed tissue samples from 76 people and identified 48 proteins whose levels increase with age. Notable changes were recorded at ages 45 and 55. The findings could help develop a blood test to measure the rate of aging.
Fresh scientific data published in Popular Mechanics challenge the notion of uniform aging. Researchers studied tissue samples from 76 people aged 14 to 68 who died from traumatic brain injuries. Comparing proteins in various organs, they found that age-related changes occur at different rates. Blood vessels, especially the aorta, begin to age faster than other tissues after about age 50. The adrenal glands show signs of aging as early as age 30. Scientists identified 48 proteins whose levels increase as tissues age. Particularly pronounced changes were recorded at ages 45 and 55, indicating periods of accelerated aging. Researchers suggest that the circulatory system may play a key role in spreading aging processes throughout the body via molecules carried in the blood. In the future, these data could help develop a blood test to determine biological age and early detection of cardiovascular and neurodegenerative disease risk. However, scientists emphasize that the results currently only help understand the biology of aging, but do not allow precise prediction of specific disease development.
