“Lactobacillus acidophilus and Bifidobacterium longum supernatants upregulate the serotonin transporter expression in intestinal epithelial cells

Conclusions: L. acidophilus and B. longum supernatants can upregulate SERT mRNA and protein levels in intestinal epithelial cells.”

Does this mean something?

No because it's sert loss in the brain which is the issue. The literature shows evidence that ssri's have changed our mrna which has decreased sert expression in the dorsal raphe.
