Scientists have found a new way to slow aging and prolong life


A group of American researchers from the Centre for healthy ageing and Us National Institute of health, found that the coenzyme NAD+ plays a key role in regulating the rate at which the body ages. As shown by experiments on animals, these molecules could potentially be used to slow aging and likely to increase life expectancy.

The cofactors, or coenzymes — small molecules of non-protein nature, connecting with the corresponding proteins, called epowerment. Coenzyme NAD+ is the oxidized form of nicotinamide adenine dinucleotide molecules involved in redox reactions and carries electrons from one reaction to another. NAD+ is an oxidizing agent and takes electrons from another molecule; it reduces to NADH, which then serves as a reducing agent and donates electrons. That this coenzyme plays an important role in ensuring the normal operation of the body, specialists have been aware for quite some time, but its effect on the aging process remains not fully understood.

Scientists have introduced NAD+ laboratory mice and round worms, and noticed that after that their rate of aging decreased, and they lived longer on average than those animals that did not receive injections.

Experts hope that their findings will be useful later in the development of new methods of dealing with such “age” of neurodegenerative diseases like Alzheimer’s and Parkinson’s disease, and will also allow in General to improve the health status of older people.

This is not the only recent study on ageing. Some other works devoted to “natural” factors that affect this process (in particular, a number of studies have shown that a good education slow down aging and psychological trauma in childhood — accelerate). At the same time, a number of scholars had a rather bold experiments designed to intervene in the aging process much more directly — for example, recently the Russian biophysicist Alex Karnaukhov decided to experience a method of life extension that involves the collection of stem cells from the bone marrow, further “freeze” and return to the body years later.
