Abstract

We focused on the biological activity of the collagen extracts obtained from the giant edible jellyfish Nemopilema nomurai Jellyfish collagen extracts stimulates the production of immunoglobulins Igs and cytokines by human hybridoma cells and human peripheral blood lymphocytes Therefore we examined the immunoregulatory function of jellyfish collagen extracts in mice Intake of jellyfish collagen extracts facilitated the Ig production activity of lymphocytes from spleen and Peyer’s patch Furthermore the levels of Igs in the serum clearly increased after the administration of jellyfish collagen extracts Intake of bovine collagen from Achilles’ tendon also activated lymphocytes activity in mice The activity of total and antigenspecific Ig production in splenocytes from OVAchallenged mice was also enhanced by collagen intake However the total and OVAspecific IgE levels in the serum were not affected by the collagen intake These results suggested that jellyfish collagen extracts stimulates an immune response in vivo without inducing allergic complications
