Does brain aging begin in the vascular plexuses?

The authors of the work, published recently in the journal Science, found out what the aging of the brain is expressed in. They even suggested a way to scroll back in time.

With age, the brain "shrinks"

The volume of the human brain gradually increases until about 40 years old, after which it begins to slowly decrease and by the end of life approximately corresponds to the size of the brain of a 7-year-old child.

Intelligence and aging

Scientists have come to the conclusion that intensive intellectual activity and high IQ have different effects on the life expectancy of men and women: the "strong sex" rejuvenates, and the "weak", on the contrary, ages.

Why age reduces the ability of muscles to recover

The age-related decrease in the ability of muscle tissue to regenerate is due to an increase in the activity of the signaling mechanism that suppresses the symmetrical division of stem cells.

Another "centenarian gene"

Spanish biologists have discovered several variants of the APOB gene that help a person live up to a hundred years or more. The work of this gene is associated with lipid metabolism, and due to its special variant, little "bad" cholesterol is formed in the body.

Why don't old people sleep well?

American scientists have explained why older people suffer from insomnia and often wake up ahead of time. Brain magazine reports on a group of inhibitory neurons, the deficiency of which leads to sleep disorders in the elderly.

Cellular aging: from physiology to pathology

Physiological aging of cells does not cause aging of the body. First of all, it is a mechanism for removing unnecessary cells, but it can also act as a "double-edged sword" for the body.

Chronic inflammation accelerates aging

Inflammation should be considered as a potential cause of aging. And the nonsteroidal anti-inflammatory drug ibuprofen can restore the regenerative abilities of tissues and prevent the physiological aging of cells.

Metabolomics: epigenetic markers of aging

The search for molecular markers that allow you to tell how old you and your cells are without looking at the passport can be interesting from many points of view: from the diagnosis of diseases to the search for criminals and the study of the aging process itself.

Melatonin strengthens aging bones

Melatonin-containing dietary supplements increase the bone strength of old mice, but it is still premature to talk about their benefits for human bones.

Growth, the FOXO3 gene and longevity

Scientists led by Professor Bradley Wilcox of the University of Hawaii managed to trace the relationship between human growth, the "long-lived" allele of the FOXO3 gene and life expectancy.

Dogs will help to understand the issues of aging

Dogs have a huge potential as a model system for studying human aging, the use of which should make a huge contribution to the development of this research area.

Don't keep parrots in solitary confinement

Jacko's parrots have once again confirmed that social stress has a bad effect on the state of chromosomes. If these very sociable birds were kept singly, then the telomeric sections of their chromosomes shortened faster than expected.

Aging brain needs REST

Active in the period of intrauterine development, the REST gene protects neurons from stressful influences in the later stages of life, and a decrease in its expression in old age is associated with Alzheimer's disease.
