近年来发现巨噬细胞在体外对淋巴细胞转化应答具有协助和抑制两重作用。本文作者为了了解肝巨噬细胞是否与腹腔等处的巨噬细胞一样也有两重作用,并为探讨这两种相反作用的关系及机理,在刀豆素A诱发大鼠淋巴细胞转化试验中,加入各种不同浓度的大鼠肝巨噬细胞,以观察巨噬细胞对淋巴细胞转化应答的影响。结果发现,肝和腹腔巨噬细胞在同样的实验条件下对淋巴细胞刀豆素A转化应答所起的附加细胞作用表现方 In recent years, it has been found that macrophages have the dual roles of assisting and inhibiting lymphocyte transformation in vitro. In order to understand whether hepatic macrophages have dual roles as peritoneal macrophages and so on, and to explore the relationship between the two opposite effects and mechanism, in the concanavalin A-induced rat lymphocyte transformation test, Various concentrations of rat liver macrophages were added to observe the effect of macrophages on lymphocyte transformation response. The results showed that the liver and peritoneal macrophages in the same experimental conditions on the conversion of lymphoid cypressin A additional role in the expression of additional cells
