Lactobacillus rhamnosus GG(ATCC 53103) is one of the best researched probiotic strains in the world. Studies in children have shown that Lactobacillus rhamnosus GG effectively prevents early atopic disease in patients with high risk. The active molecules associated with the immunostimulatory sequence and anti-allergy effects of L. rhamnosus GG have not yet been identified. Unmethylated CpG motifs in bacterial DNA have a mitogenic effect in mouse immune cells, CpG-containing ISS oligodeoxynucleotides are potent Th1 adjuvants, effective in both preventing and reversing Th2-biased immune deviation in allergy models. The genomic DNA of L. rhamnosus GG is a potent inducer of murine B cell and dendritic cell immunoactivation. In L. rhamnosus GG genomic DNA, ID35 shows high activity in ISS assays in both mice and humans. The effects of ID35 result from a unique TTTCGTT motif located at its 5'-end, and its effects are comparable with murine prototype CpG 1826. L. rhamnosus GG is known to secrete proteinaceous pili encoded by the spaCBA gene cluster. The presence of pili structures may be essential for its adhesion to human intestinal mucus, explaining the prolonged duration of intestinal residence of this bacterium, compared to that of non-piliated lactobacilli.
