众所周知,在机体防御感染中吞噬鼠疫菌起重要作用,然而,肺损伤时,什么样的上皮细胞参与吞噬反应至今仍未查明,近年来许多研究者否认不同来源的肺泡巨噬细胞的作用。曾证实,在用 EB 鼠疫菌免疫动物时,明显地增加了吞噬活性升高的肺泡巨噬 It is well-known that phagocytic plague plays an important role in the defense of the body. However, it is still unknown what type of epithelial cells participate in phagocytosis during lung injury. In recent years, many researchers have denied the role of different sources of alveolar macrophages. It has been demonstrated that when the animals were immunized with EB plague bacteria, the alveolar macrophages with increased phagocytic activity were significantly increased
