Our results showed that pigs fed LGG and infected with A. suum had reduced levels of IL-13, a key cytokine regulating allergic responses to parasitic infection, eotaxin 3 (CCL26), one of the three related chemokines that specifically activates CCR3 receptor in eosinophils, and eosinophil peroxidase (EPX), suggesting an inhibition of eosinophil recruitment and function in TBLN draining the lungs of A. suum infected pigs. The gene discussed is EPX; the disease is parasitic infectious disease.
