GM suppressed larval invasion and abrogated the rTsgal promoting role on the invasion. A: The invading larvae were mobile and migratory in the monolayer (the red arrow shows migratory trace). B and C: Non-invading worms were coiled on the surface of the IECs (B) and C2C12 cells (C). D: rTsgal accelerated IIL invasion into IECs. E: GM inhibited the IIL invasion of IECs in a GM dose-dependent manner. F and G: GM inhibited and abrogated the rTsgal facilitation effect on IIL invasion of IECs. Scale bars: 100 μm. * p < 0.05 compared to the PBS group (D and E) or only rTsgal groups (F and G).
