The higher dose of the probiotic strain B. lactis upregulated CCL2 and CCL5 mRNAs (Figure 5G,H, respectively), despite downregulating them on BALF of Schizophrenic patients when co-administered with Lactobacillus rhamnosus [62] and on TNBS-induced colitis mice when co-administered with Lactobacillus plantarum and Streptococcus thermophilus [63]. Here, CCL5 is linked to colitis.
