Gut microbiota rescues vascular cognitive impairment by improving glymphatic function via the ILA-AHR-AQP4 pathway.
Pharmacological research·September 25, 2026·PMID 42790831
Why it mattersVascular cognitive impairment lacks effective treatments. This paper identifies a gut-brain mechanism—microbial ILA activating astrocytic AHR to regulate AQP4 and glymphatic clearance—that could be targeted by microbiota-based or metabolite-based interventions, offering a novel therapeutic avenue for cognitive decline associated with cerebral hypoperfusion.
