IL13 and infection: By detecting CD4+ T cell subtypes from spleen cells of mice infected with S. japonicum after 7 weeks of infection, we found that myricetin increased the proportion of Th1 cells but decreased the proportion of Th2 and Th17 cells, and ELISA also demonstrated elevations in plasma IFN-γ, IL-12, and IL-7 with concurrent reductions in plasma IL-4, IL-5, IL-10, IL-13, and IL-17A, indicating that myricetin modulates the immune response in schistosome-infected mice.
