炭疽疫苗及治疗药物筛选和评价模型研究进展

炭疽疫苗和治疗药物的研究是近年来国际上研究热点之一,由于对它们的有效性研究不能在人体进行,因此实验模型的选择就特别重要.目前常用的细胞模型主要包括CHO细胞和J774A.1细胞.动物模型种类较多,包括小鼠、大鼠、豚鼠、兔和猴等都被作为炭疽的动物模型加以研究.由于模型选择的差异,实验结果常出现较大差异,甚至得到相反的结果.回顾了以往在细胞和动物模型上进行的炭疽实验,分析选择炭疽研究模型的原则和依据.同时,为探讨不同模型之间产生实验结果差异的原因,简要介绍了炭疽杆菌的致病机理,以及炭疽疫苗和治疗药物的研究进展.

Animal and Cell Models on Screening and Evaluating Vaccines and Drugs Against Anthrax

Recently the research of vaccines and drugs against anthrax is one of hot spots. The efficacy of anthrax vaccines and drugs can't be experimented in human, therefore the testing model is very important. The cell models mainly include CHO and J774A.1. Now, various kinds of animals including mice, rats, rabbits, and nonhuman primates were experimented as animal models. Because the models are different, the results of experiments are significantly different, sometimes they are contrary. Many experiments of Bacillus anthracis in different cell and animal models are reviewed, and the principles of choosing animal models of anthrax are discussed. In order to analyze the different results of experiments in different models, the pathogenesis of Bacillus anthracis and the researching progress of anthrax vaccines and drugs are also simply introduced .
