The article presents a study stating that DNA derived from probiotic bacteria modulates human dendritic cell phenotype and function. Unmethylated CpG motifs, predominantly present in bacterial DNA, can be immunostimulatory via toll-like receptor (TLR)-9. Commensal bacteria play a role in maintaining immune homeostasis in the gut. Dendritic cells (DC) are modulated by microbial products, including DNA, to shape a developing T cell response. Therefore, the study determined the effects of DNA derived from probiotic bifidobacteria, lactobacilli, and Streptococcus thermophilus on DC.

    "Day-7" myeloid DCs are commonly used in the clinic. However, there is a strong need to develop DCs faster that have the same potent immunostimulatory capacity as "Day-7" myeloid DCs and at the same time minimizing time, labor and cost of DC preparations. Although "2 days" DCs can elicit...
