Scientists reverse the aging of mouse brains with poo transplants from young mice
Since almost a decade, evidence has accumulated that the composition of the microbiome changes with age. My colleagues at University College Cork conducted 2,012 studies that showed the diversity of microbiome to be linked with health outcomes later in life, such as frailty.
Elie Metchnikoff, who turned 50 in 1895, became more and more concerned about the aging process. The Russian Nobel Prize-winning scientist and one of the pioneers of immunology began to worry about aging.
He was fascinated by intestinal bacteria and their role in health. He suggested that eastern Europeans lived longer as they consumed fermented food containing lactic acids bacteria.
Scientists ignored this theory, which was popular at the time but linked gut microbes with healthy aging. This is only relatively recent. Now we recognize the role that trillions of bacteria in the gut microbiome play in regulating both health and disease.
