Asterias Rubens (Echinoderm): Evidence of Lymphocytes, Lymphokines and Invertebrate Primitive Antibody(IPA).Expected Rôle of Tiedemann’s Bodies

Abstract

The axial organ is considered as ancestral lymphoïd organ. It contains T and B sea star lymphocytes and Phagocytes. It plays a fundamental rôle in the sea star cell-mediated immune responses and humoral immune ones.Asterids belong to Echinoderma (Invertebrates).An expected rôle of Tiedemann’s bodies is evoked.
