Influence of Lactobacillus pentosus S-PT84 Ingestion on the Mucosal Immunity of Healthy and Salmonella Typhimurium-Infected Mice.

Lactobacillus pentosus (L. pentosus) strain S-PT84, isolated from Kyoto pickles, enhances splenic natural killer (NK) cell activity, and has high T-helper1 (Th1) cytokine and type 1-IFN (IFN-α) inducing activity. In the present study, we investigated the influence of S-PT84 ingestion on the mucosal immunity of healthy and Salmonella Typhimurium (S.

Antiallergic effects of Lactobacillus pentosus strain S-PT84 mediated by modulation of Th1/Th2 immunobalance and induction of IL-10 production.

Background: Many types of fermented food are consumed in Japan. Although some are produced by plant-origin lactic-acid bacteria (LAB) fermentation, the physiological functions of such bacteria remain unclear. We therefore isolated LAB of plant origin from Kyoto pickles and determined the immunological activity of heat-killed preparations of plant-origin LAB.
