A Gut-Brain Connection: Probiotics L9 and A6 Offer New Insights into AD Prevention

Accumulating evidence suggests that probiotics affect the microbial-gut-brain axis in a way that can prevent and treat Alzheimer's disease (AD). However, the mechanism underlying the therapeutic effects still needs to be further investigated. This study aimed to examine the alleviating effect of Lacticaseibacillus paracasei L9 (L9) and Bifidobacterium animalis subsp. lactis A6 (A6) and possible mechanism in mice with AD.
