Arylsulphatase in echinoderm immunocompetent cells

Two peaks of arylsulphatase activity were detected biochemically in coelomocyte lysate preparations of seven different Echinodermata species. Both peaks were inactivated by sulphite and sulphate ions, indicating that Type II arylsulphatase is present in the coelomocytes of the species tested. Arylsu...

Description
Summary:Two peaks of arylsulphatase activity were detected biochemically in coelomocyte lysate preparations of seven different Echinodermata species. Both peaks were inactivated by sulphite and sulphate ions, indicating that Type II arylsulphatase is present in the coelomocytes of the species tested. Arylsulphatase was localized histochemically in the granules of spherula cells, suggesting that in echinoderms a common cell type with granulocyte-like functions is present. The enzyme was also localized in the amoebocytes of echinoid species.
