The results of ELISA and RT-qPCR showed that TM can exacerbate the allergic reaction by reducing the mRNA expression of tight junction (TJ) proteins (such as ZO-1, claudin-3, Occludin) in the jejunum, destroying the intestinal barrier function, increasing the permeability, and promoting the release of inflammatory factors (such as IL-8, TNF-α) and histamine. The gene discussed is CXCL8; the disease is allergic disease.
