The elixir of longevity: scientists find a method to prolong life.

American researchers from the Baylor University of Medicine and the Health Center of the University of Houston (Texas, USA) said they had found a method to lengthen the life of human beings. The study carried out by the specialists has been published in the journal Cell.

Through a system based on the use of intestinal flora, scientists have already determined which are the strains of microorganisms that prevent the accumulation of beta-amyloids, molecules formed by the union of several amino acids and linked to the development of Alzheimer’s. . Likewise, they have managed to slow the growth of malignant tumors also with the use of bacteria.

«We are increasingly aware that the interaction of our organism with millions of microbes influences many processes, such as metabolic activity and aging,» said Meng Wang, one of those responsible for the study.

During the investigations, the specialists carried out experiments in nematodes (Caenorhabditis elegans), commonly known as roundworms.
«We introduced the bacteria into primitive organisms and then we analyzed the life span of the worms.» Of about 4,000 bacterial genes that were subjected to experiments, the elimination of 29 turned out to have a positive effect on the longevity of the nematodes. The bacteria also protected the worms from tumor growth and the accumulation of beta-amyloid, closely linked to Alzheimer’s disease in humans, «the scientist added.

Based on the results of the study, the researchers determine that it is possible to create medicines that contain intestinal flora that slows aging.
