Mannose reduced the rTsCTL facilitative effect on larval invasion of IECs. rTsCTL (10 μg/mL) was first incubated with various doses of mannose (0–400 mM) for 2 h, and then, the IILs mixed with mannose-treated rTsCTL were added to the IEC monolayer and cocultured for 2 h. Mannose (200 and 400 mM) significantly reduced the rTsCTL facilitative act on larval invasion of IEC. *P < 0.05 compared to the PBS group.
