[Studies on dynamic changes of proportions of Tc1 and Tc2 cells during Schistosoma japonicum infection].

The proportions of Tc1 cells and Tc2 cells in T cells are significantly increased at different stages after S. japonicum infection. Tc1 cells are increased most quickly 3 weeks post-infection, and Tc2 cells are increased most quickly 5 weeks post-infection. A positive correlation is found between the proportions of Th cells and Tc cells in CD3+ T cells. SWA preferentially induces the increase of Tc1 cells in CD3+ T cells while SEA preferentially induces the increase of Tc2 cells in CD3+ T cells in vitro.
