Transplanting fecal microbiota from young mice to older mice reversed hallmark signs of aging in the gut, brains, and eyes. Transplanting the fecal microbiota from old to young mice had the reverse effect, inducing inflammation in the brain and depleting a key protein associated with healthy vision.
Microbes in the gut influence what an animal chooses to eat. Altering the microbiome resulted in changes to preferred diets.
Hypothalamic neurons directly detect variations in bacterial activity and adapt appetite and body temperature accordingly. The findings demonstrate a direct dialog occurs between the brain and the gut microbiota.
