Fig. 1From: Immunoregulatory effects triggered by immunobiotic Lactobacillus jensenii TL2937 strain involve efficient phagocytosis in porcine antigen presenting cellsPhagocytosis of immunobiotic Lactobacillus jensenii TL2937 by mononuclear phagocytes from porcine Peyer’s patches (PPMPs). Adherent PPMPs were treated with the immunobiotic strain L. jensenii TL2937 or the non-immunoregulatory strain L. plantarum TL2766. Untreated adherent PPMPs were used as controls. Bacterial phagocytosis by adherent CD172a+CD11R1+ or CD172a−CD11R1+ PPMPs was evaluated using flow cytometric analysis. Histograms represent data from the flow cytometric analysis as follows: cells treated with lactobacilli (solid line), and untreated control cells (dot line) (a). Isolated CD172a+ PPMPs cells were obtained by a MACS cell separation system (magnetic cell labeling). Isolated CD172a+ cells were treated with L. jensenii TL2937 or L. plantarum TL2766. Bacterial phagocytosis was evaluated using flow cytometric analysis (b). In all the experiments cells were used in a concentration of 5.0 × 106 cells/well. Values of mean fluorescence intensity (MFI) are shown for each group. The results represent data from three independent experiments using different donorsBack to article page
