Abstract

To elucidate a mutual correlation between the hemolymph lectin and hemocytes of the pearl oyster, Pinctada facata martensii, we searched for common epitopes and ligands. Neither the hemocyte plasma membrane nor cytoplasm was immunoreactive to anti-hemolymph lectin antibody. The hemolymph lectin strongly bound to D-galactose and N-acetyl-D-galactosamine, and the plasma membrane of both granulocytes and agranulocytes had affinity only for D-mannose and N-acetyl-D-glucosamine-binding plant lectins. In the gonad, the hemolymph lectin selectively adsorbed injected horse red blood cells (HRBC), and its hemagglutinating activity probably prevented them from dispersing. Pinctada sp. may possess system of recognition of non-self by the hemolymph lectin.
