Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
