Immunohistochemical localization of hepatopancreatic phospholipase in gastropods mollusc Littorina littorea and Buccinum undatum digestive cells

摘要

BackgroundAmong the digestive enzymes, phospholipase A2 (PLA2) hydrolyzes the essential dietary phospholipids in marine fish and shellfish. However, we know little about the organs that produce PLA2, and the ontogeny of the PLA2-cells. Accordingly, accurate localization of PLA2 in marine snails might afford a better understanding permitting the control of the quality and composition of diets and the mode of digestion of lipid food.
