Peritoneal macrophages and splenic lymphocytes were collected from BALB/c mice, normal or previously infected with Echinococcus multilocularis. In an accessory cell function assay, peritoneal macrophages, in increasing numbers, were added to cultures of splenic lymphocytes. Cultures were stimulated by concanavalin A (Con A) or E. multilocularis culture supernatant (EMSN). Post-infection macrophages, unlike normal macrophages, suppressed Con A- and EMSN-driven lymphocyte transformation. Modification of accessory cells could also be repeatedly induced in vivo by EMSN or a single FPLC fraction of EMSN. Lymphocytes were made more sensitive to accessory cell signals following incubation with EMSN.
从正常或先前感染多房棘球绦虫的BALB/c小鼠中收集腹膜巨噬细胞和脾淋巴细胞。在辅助细胞功能测定中,将数量不断增加的腹膜巨噬细胞添加到脾淋巴细胞培养物中。培养物用刀豆蛋白A(Con A)或多房棘球绦虫培养上清液(EMSN)刺激。与正常巨噬细胞不同,感染后的巨噬细胞抑制Con A和EMSN驱动的淋巴细胞转化。EMSN或EMSN的单一FPLC组分也可在体内反复诱导辅助细胞的改变。淋巴细胞在与EMSN孵育后对辅助细胞信号更敏感。
