title: Mitogenic andadjuvant activities of polysaccharides from the cellular slime mold, Dictyostelium discoideum NC-4.
abstract: Cell surface and extracellular polysaccharide fractions obtained from Dictyostelium discoideum NC-4 cultured in bacteria-free medium showed strong B-cell mitogenic activities. Upon periodate treatment of the extra-cellular polysaccharide fraction this activity completely disappeared. The extracellular polysaccharide fraction could also enhance the antibody response in vitro against sheep red blood cells.
