TGFB1 and digestive system infectious disorder: To explore the impact of FAEW on neuroendocrine signaling related to intestinal infections and bloating, we examined the gene expression of key components in the serotonin biosynthesis pathway (tph‐1) [23], the DAF‐7/TGF‐β pathway (daf‐7), and the NPR‐1/GPCR pathway (npr‐1, flp‐18, and flp‐21).
