Antibody Dependent Cytotoxicity In Hemocytes Of The Mud Crab Scylla Tranquebarica

Though phagocytosis is well known in hemocytes, the receptors in hemocytes which recognize the opsonising proteins are not yet investigated. Hence, in this present study an attempt was made to find clues on the similarities of the receptors with the Fc receptors in immune cells of mammals. Fixed hemocytes after treating with human IgG were injected into the animal’s body and after incubation, the IgG sensitized cells were removed from the in vivo system which was evidenced by indirect agglutination test and microscopic observation. Hence, it is construed that hemocytes can recognize the human IgG bound hemocytes and phagocyte them.
