A Cognitive Rejuvenating Effect with Gut Microbe Transplant

A novel approach to reverse aspects of ageing-related deterioration in the brain and cognitive function via the microbes in the gut was revealed in research published in Nature Aging.

With ageing populations increasing worldwide, a key challenge is the development of strategies to maintain healthy brain function. This ground-breaking research with gut microbes lays open new possibilities such as microbial-based interventions to slow down brain ageing and cognitive problems associated with it.

The work was carried out by researchers at Microbiome Ireland (APC) at University College Cork (UCC).

There is a growing appreciation of the importance of the microbes in the gut on all aspects of physiology and medicine. In this most recent study, the authors demonstrated that by transplanting gastrointestinal microbes from young into old mice, they were able to rejuvenate aspects of brain and immune function.

Study leader Professor John F Cryan said: “Previous research published by the APC and other groups internationally has shown that the gut microbiome plays a key role in aging and the ageing process. This new research is a potential game changer, as we have established that the microbiome can be harnessed to reverse age-related brain deterioration. We also see evidence of improved learning ability and cognitive function”.

Despite the promising results, Prof Cryan cautioned that “it is still early days and much more work is needed to see how these findings could be translated in humans”.

APC Director Prof Paul Ross stated that “This research of Prof Cryan and colleagues further demonstrates the importance of the gut microbiome in many aspects of health, and particularly across the brain/gut axis where brain functioning can be positively influenced. The study opens up possibilities in the future to modulate gut microbiota as a therapeutic target to influence brain health”.
