Gut Bacterial Molecule Linked to Alzheimer’s-Related Brain Changes
Tiny organisms live in our intestines and help with many body processes.
Some of these bacteria make a substance called ImP.
Scientists want to know if ImP might affect the brain as people get older.
A new study looked at both people and mice.
It found that higher levels of ImP may be associated with brain changes linked to Alzheimer’s disease.
This does not show that ImP causes Alzheimer’s.
More details about the study are not provided in the article excerpt.
Researchers are investigating whether gut microbes can affect the ageing brain.
The molecule under study is imidazole propionate, also called ImP.
Some gut bacteria produce ImP when breaking down an amino acid found in proteins.
The research involved both humans and mice.
Higher ImP levels may be associated with brain changes linked to Alzheimer’s disease; the report does not establish causation.
- Who
