Adult splenectomized mice exhibit increased resistance to infection with Listeria monocytogenes. Phagocytosis, by reticulo-endothelial cells, of test particles (51Cr-labelled sheep erythrocytes) is the same in splenectomized and control mice. However, 24 h exposure to Listeria, which fails to influence phagocytic activity of normal mice, greatly enhances the blood clearance and liver uptake of the test particles in splenectomized mice. The presence of a cell population and/or product in the spleen which modulates macrophage activation upon the exposure to appropriate stimuli is postulated.
成年脾切除小鼠对单核细胞增生李斯特菌感染的抵抗力增强。脾切除小鼠和对照小鼠中,网状内皮细胞对测试颗粒(51Cr标记的绵羊红细胞)的吞噬作用相同。然而,正常小鼠接触李斯特菌24小时后,吞噬活性未受影响,但脾切除小鼠的测试颗粒血液清除率和肝脏摄取量大大增加。推测脾脏中存在一种细胞群和/或产物,在接触适当刺激后可调节巨噬细胞的激活。
