Scientists Found a Microbial Transfer That Reversed Biological Age Decline in Damaged Gut Tissue
Indian Defence Review • • health
Key Points:
- The mammalian gut lining regenerates rapidly through intestinal stem cells (ISCs), but this process slows with age, leading to thinner intestinal walls and reduced recovery from injury or inflammation.
- Research indicates that the gut microbiome plays a crucial role in aging, with fecal microbiota transplantation (FMT) from young to old mice reversing age-related decline by restoring gut structure and function.
- FMT reactivates dormant intestinal stem cells in older mice through microbial metabolites like indoles and short-chain fatty acids, improving tissue regeneration and reducing chronic inflammation.
- The bacterium Akkermansia muciniphila, abundant in young mice, supports gut health by maintaining the mucus layer and promoting a protective environment for stem cells, but its levels decline with
