Dietary proanthocyanidins ameliorate age-related cognitive decline and neuroinflammation in thyroxine-induced accelerated aging-like mice via the gut microbiota-SCFAs-5-HTP axis.
Age-related cognitive impairment is a major public health concern associated with neuroinflammation and gut microbiota dysbiosis. Proanthocyanidins (PC), a class of dietary polyphenols, have been suggested to modulate the gut-brain axis. Here, we investigated the mechanisms by which PC alleviate cognitive deficits in a...
