Lactobacillus acidophilus La5, Bifidobacterium BB12, and Lactobacillus casei DN001 modulate gene expression of subset specific transcription factors and cytokines in peripheral blood mononuclear cells of obese and overweight people.

Probiotics are believed to have interaction with immune cells through sustained effects on gene expression of different cytokines and transcription factors. The present randomized doubled-blind controlled clinical trial was performed recruiting 75 individuals with BMI 25-35, who were randomly assigned to the following three groups: Group 1 (n = 25) who consumed regular yogurt as part of a low calorie diet [RLCD], group 2 (n = 25) who received probiotic yogurt with a LCD [PLCD] and group 3 (n = 25) who consumed probiotic yogurt without LCD [PWLCD] for 8 week. Participants in PLCD and PWLCD groups received 200 g/day yogurt containing Lactobacillus acidophilus La5, Bifidobacterium Bb12, and lactobacillus casei DN001 10(8) cfu/gr.
