随着新的免疫理论和免疫检测手段的日益出现,免疫毒理学取得了迅速的发展。现在,免疫毒理学不仅是评价化学物对免疫系统损害的一门学科,而且免疫机能障碍与肿瘤发病率增高之间的关系也引起了人们的注意。研究表明,许多化学物质可以通过破坏机体免疫监视功能而诱发肿瘤的产生。近年来有关K细胞和NK细胞的功能,特别是在抗肿瘤免疫中的作用受到了广泛的关注。有些学者指出,K细胞和NK细胞功能的降低或失调将可导致肿瘤的产生。目前有关化学物对K细胞和NK细胞功能的影响是免疫毒理学研究的一个热 With the emergence of new immunological theories and immunological detection methods, immunotoxicology has achieved rapid development. Now, immunotoxicology is not only a subject for evaluating the damage of chemicals to the immune system, but also the relationship between immune dysfunction and increased incidence of tumors has attracted attention. Studies have shown that many chemicals can induce tumors by disrupting immune surveillance. In recent years, the functions of K cells and NK cells, especially their role in anti-tumor immunity, have received extensive attention. Some scholars have pointed out that a decrease or imbalance in the function of K cells and NK cells can lead to tumors. The current influence of chemicals on K-cell and NK cell function is a hot topic in immunotoxicology research
