The role of superoxide anion generation in antibody-dependent polymorphonuclear leukocyte-mediated cytotoxicity. 1979

F Capsoni, and P L Meroni, and A Lazzarin, and O Marzatico

Human polymorphonuclear leukocytes (PMNs) can act as killer cells in an antibody-dependent cellular cytotoxicity (ADCC) system. Cytolysis is rapid and detectable at low effector/target cell ratios. PMNs from a patient affected by chronic granulomatous disease (CGD) exhibit an absolute defect in ADCC. In order to investigate the role of the toxic oxygen derivatives (H2O2 and superoxide anions) lacking in CGD, experiments in presence of specific inhibitors were carried out. Superoxide dismutase, an O-2 scavenger, displayed a significant inhibition activity in a dose dependent way. On the other hand neither catalase, which degrades H2O2, nor sodium azide, a myeloperoxidae inhibitor, affect the cytotoxic activity. Our results suggest that the importance of the intact oxidative metabolism in PMN-mediated ADCC against chicken red blood cells could be referred to the correlated production of O-2 anions.

UI	MeSH Term	Description	Entries

D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D002645	Chickens	Common name for the species Gallus gallus, the domestic fowl, in the family Phasianidae, order GALLIFORMES. It is descended from the red jungle fowl of SOUTHEAST ASIA.	Gallus gallus,Gallus domesticus,Gallus gallus domesticus,Chicken
D006105	Granulomatous Disease, Chronic	A defect of leukocyte function in which phagocytic cells ingest but fail to digest bacteria, resulting in recurring bacterial infections with granuloma formation. When chronic granulomatous disease is caused by mutations in the CYBB gene, the condition is inherited in an X-linked recessive pattern. When chronic granulomatous disease is caused by CYBA, NCF1, NCF2, or NCF4 gene mutations, the condition is inherited in an autosomal recessive pattern.

D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D006861	Hydrogen Peroxide	A strong oxidizing agent used in aqueous solution as a ripening agent, bleach, and topical anti-infective. It is relatively unstable and solutions deteriorate over time unless stabilized by the addition of acetanilide or similar organic materials.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
