Abstract
Beta-glucans are well known for their immunomodulatory capacities in human and mice. For this reason together with the European ban on growth-promoting antibiotics, b-glucans are intensively used in pig feed. However, as described in the present study, there is much variation in the stimulatory capacity between b-glucans of different sources. As dendritic cells (DCs) are the first cells which are encountered after an antigen is taken up by the intestinal epithelial cell barrier, we decided to investigate the effect of two concentrations (5 and 10 µg/ml) of five commercial b-glucanpreparations, differing in structure and source, on porcine monocyte-derived dendritic cells (MoDCs). Although all b-glucans gave rise to a significant reduction of the phagocytic activity of DCs, only Macrogard induced a significant phenotypical maturation. Besides Macrogard, also zymosan, another b-glucan derived from Saccharomyces cerevisiae, and curdlan significantly improved the T cell stimulatory capacity of MoDCs. Most interesting however, is the cytokine secretion profile of curdlan-stimulated MoDCs as only curdlan induced significant higher expression levels of IL-1b, IL-6, IL-10 and IL-12/IL-23p40. As the cytokine profile of DCs influences the outcome of the ensuing immune response and thus may prove valuable in intestinal immunity, a careful choice is necessary when b-glucans are used as dietary supplement.
