Concentration of LDH in supernatants of IPEC-J2 cells. IPEC-J2 cells added with DMSO were regarded as the vehicle control and L. salivarius-involved IPEC-J2 cells were supplemented (a) without inhibitor, (b) with 10 μmol/L SB-203580 (p38 MAPK inhibitor), (c) with10 μmol/L SCH772984 (ERK MAPK inhibitor) and (d) with 10 μmol/L BAY11-7082 (NF-κB inhibitor), respectively. Concentration of LDH was detected after ETEC K88 challenge. Data are presented as means ± SEM of three independent experiments. *, P < 0.05; **, P < 0.01; ***, P < 0.001
