摘要：
The mechanism of neutrophil leucocytosis in cases of Japanese encephalitis is not known, We here report that during Japanese encephalitis virus (JEV) infection in mice the splenic macrophages secrete a chemotactic factor that attracts the neutrophils. The peak activity of macrophage derived factor (MDF) was observed on day 7 following infection. The MDF acted in a dose-dependent manner. This chemoattractant was purified by low pressure liquid chromatography and gave a single band of 10 kD on silver stained polyacrylamide gel. The MDF was found to be heat resistant and sensitive to prolonged incubation with proteases.
