Abstract

Due to the new coronavirus infection pandemic, the global scientific community has been forced to change the direction of the most research, focusing on vaccine development as well as the search for new antiviral drugs to treat COVID-19. The choice of experimental models, timeframe and approaches for evaluating drugs and vaccines under development is crucial for the development of effective measures to prevent and control this disease.The purpose of this review was to summarize the relevant data concerning the susceptibility of laboratory animals to SARS-CoV-2. This paper describes the most virus-susceptible animal species that can be used to reproduce coronavirus infection, stressing the main advantages and disadvantages of each of them.According to the latest data, small rodents (Rodentia) and non-human primates (Strepsirrhini) are commonly used in the scientific community to model coronavirus infection. The viral load in the upper and lower parts of the respiratory system, clinical symptoms of infection (weight loss, body temperature and general health status), pathomorphological picture in target organs and the production of antibodies after infection are considered to the main markers of pathology. Despite the vast amount of data, none of the described models of SARS-CoV-2 infection may be considered a gold standard, since they do not reproduce all spectrum of morphological and pathogenetic mechanisms of infection, and do not fully reflect the clinical picture observed in patients in human population.Based on the analyzed literature data, we suppose that Syrian hamster (Mesocricetus auratus) and mice (Muridae) expressing the angiotensin converting enzyme receptor 2 (ACE2) are the most suitable animal species for their use in experiments with SARS-CoV-2 infection. The development of neutralizing antibodies makes it possible to evaluate the efficacy of vaccines, while the course and severity of symptoms infection makes the use of mice and hamsters especially popular for screening pharmacological substances with antiviral mechanism of action, when their administration can prevent or slow the disease progression.

摘要

由于新型冠状病毒感染大流行,全球科学界不得不改变大多数研究的方向,将重点放在疫苗开发以及寻找治疗新冠肺炎的新型抗病毒药物上。选择实验模型、时间框架以及评估正在研发的药物和疫苗的方法,对于制定有效的疾病防控措施至关重要。本综述的目的是总结有关实验动物对严重急性呼吸综合征冠状病毒2(SARS-CoV-2)易感性的相关数据。本文描述了可用于复制冠状病毒感染的最易感染病毒的动物物种,强调了每种动物的主要优缺点。根据最新数据,小型啮齿动物(啮齿目)和非人类灵长类动物(原猴亚目)在科学界常用于模拟冠状病毒感染。呼吸系统上下部的病毒载量、感染的临床症状(体重减轻、体温和总体健康状况)、靶器官的病理形态学表现以及感染后抗体的产生被视为病理学的主要标志物。尽管有大量数据,但所描述的SARS-CoV-2感染模型均不能被视为金标准,因为它们无法复制感染的所有形态学和发病机制谱,也不能完全反映人类患者中观察到的临床症状。基于分析的文献数据,我们认为表达血管紧张素转换酶受体2(ACE2)的叙利亚仓鼠(金仓鼠)和小鼠(鼠科)是用于SARS-CoV-2感染实验的最合适动物物种。中和抗体的产生使得评估疫苗的疗效成为可能,而症状感染的过程和严重程度使得小鼠和仓鼠在筛选具有抗病毒作用机制的药理物质时特别受欢迎,因为给药时它们可以预防或减缓疾病进展。
