Fig 6. Effect of treatment with L. acidophilus on PGE2 secretion in Caco-2 epithelial cells.

PGE2 secretion was significantly elevated following infection with V. cholerae/ S. sonnei and this effect was abolished when the cells were pretreated by L. acidophilus. The data are presented as mean ±SEM. The statistical data (by unpaired two-tailed Student’s t test) were signed when P <0.05. ^##significantly different of L.a+V.c+Caco-2 from V.c+Caco-2 cells. ^††† significantly different of L.a+S.s+Caco-2 from S.s+Caco-2 cells L.a: Lactobacillus acidophilus, V.c: Vibrio cholerae and S.s: Shigella sonnei. ND: None Detectable.
