Abstract

Phagocytosis, intracellular killing of Candida albicans, and superoxide production by rat peritoneal macrophages exposed to aflatoxins B1, B2, G1, G2, B2a, and M1 at several times and concentrations were analyzed to evaluate the intensity of a depressive effect for each mycotoxin. All aflatoxins used at very low concentrations had a depressive effect on the functions of macrophages. The biggest impairment of phagocytosis, intracellular killing, and spontaneous superoxide production was observed in macrophages exposed to aflatoxins B1 and M1.

摘要

分析了大鼠腹腔巨噬细胞在不同次数和浓度下暴露于黄曲霉毒素B1、B2、G1、G2、B2a和M1时的吞噬作用、白色念珠菌的细胞内杀伤以及超氧化物的产生,以评估每种霉菌毒素抑制作用的强度。所有极低浓度使用的黄曲霉毒素均对巨噬细胞功能有抑制作用。在暴露于黄曲霉毒素B1和M1的巨噬细胞中,观察到吞噬作用、细胞内杀伤和自发超氧化物产生的最大损伤。
