Killing effects of ADCC on T. spiralis NBL. The NBL were cocultivated with anti-rTsE serum and 2 × 105 mouse peritoneal exudate cells (PECs) at 37 °C for 48 h. A Live NBL; B PEC adherence to NBL; C dead NBL. D Cytotoxicity was dose-dependent for anti-rTsE antibodies. E Cytotoxicity also increased with prolonged cultivation time. *P < 0.05 compared with the preimmune serum group. Scale bars: 50 μm.
