Probiotic CFS effect on in vitro neutralization of ROS produced by PMA-stimulated human neutrophils. Supernatants of L. acidophilus (a), L. casei (b), L. lactis (c), L. reuteri (d), and S. boulardii (e) have been tested on ROS production by human neutrophils challenged with PMA for 20 minutes. Results are expressed as Relative Luminescence Unit (RLU). Data represent the mean of two independent experiments performed in triplicate. t-test, P<0.05 (CFS-treated neutrophils versus untreated neutrophils).
