New insights \”surprising\” into the link between gut microbiome aging
New research suggests that a metabolite made by gut microbes can increase neuronal production in the brain and improve intestinal function. This could slow down the aging process. The research, which included several mouse experiments, found that the negative effects associated with aging can be countered by increased microbial production.
The new research, which aims to investigate the effects of the gut microbiome in aging, first transplanted the gut microbiome between old and younger mice. The gut microbiota from older mice was colonized in young germ-free mouse using fecal transfers. The results were unexpected, as the younger mice colonized by the older microbiomes showed increased neurogenesis. This is a process in which new neurons are created in the brain.
Sven Pettersson, the leader of the Nanyang Technological University’s research team in Singapore, explains that the microbes from an older mouse can support the growth of a young mouse’s neural tissue. This is an interesting and surprising observation …\”
