The effects of lactobacilli (L. rhamnosus, L. reuteri, L. Plantarum) on LPS-induced memory impairment and changes in CaMKII-α and TNF-α genes expression in the hippocampus of rat.

In recent years, some investigations have focused on the relationship between gut microbiota and brain function in healthy and disease conditions. Moreover, changes in the gut microbiome may affect memory, behavior, and cognition. This study aimed to evaluate the effect of lactobacilli on passive avoidance learning, hippocampal CaMKII-α, and TNF-α genes expression in one experimental model of neuroinflammtion.
