Phagocytosis and hydrogen peroxide production by phagocytes of the sea urchin Strongylocentrotus nudus.


Phagocytosis of erythrocytes by phagocytes from the sea urchin Strongylocentrotus nudus can occur in vitro, and is enhanced by opsonization with the coelomic fluid. This opsonic activity of coelomic fluid can be elevated over a 5-day period by injecting erythrocytes into the coelom. Phagocytes produce hydrogen peroxide during both resting and stimulated… (More)
