[Changes of neutrophil functions resulting from intact and injured liver cells in mice].

Separately cultured parenchymatous and nonparenchymatous liver cells of mice produce factors to influence migration properties and oxygen-dependent metabolism of neutrophils. Cell-free supernatant of intact parenchymatous cells activates neutrophil chemotaxis only, while supernatant of intact nonparenchymatous cells stimulates oxygen-dependent reactions as well. Injure of the liver cells with 5 mM tetrachlormethane significantly increases neutrophil functional activation. Treatment of the liver cells with anti-liver antibodies (0.5 mg/ml) results in suppression of neutrophil activation. At the same time, supernatant of the liver cells treated with normal rabbit antibodies (0.5 mg/ml) possessed neutrophil stimulating properties, nonparenchymatous cell factors stimulating mainly the neutrophil oxygen-dependent metabolism.
