由严重急性呼吸系统综合症冠状病毒2(SARS-CoV-2)引起的持续大流行迄今已感染约2.42×107名受试者(截至2020年8月27日),超过820,000人死亡。这是过去20年来发生的第三起依赖人畜共患冠状病毒的疫情,是对全球公共卫生的重大感染威胁。与其他病毒感染类似,这种感染的一个主要方面是所谓的“细胞因子风暴”,即对病毒传播的一种不适当的分子反应,它在组织和器官损害中发挥主要作用。免疫疗法,包括疫苗和人源化的单抗,已被提出为预防和治疗该病的主要战略。因此,对病毒感染细胞并诱导免疫反应的分子事件的详细机制知识似乎是必要的。在这篇综述中,我们将报道SARS-CoV-2进入细胞的最初过程的细节,重点是Spike蛋白的成熟。然后,将特别关注描述树突状细胞可能的机制,树突状细胞是先天和获得性免疫反应的主要细胞成分,可能在病毒在人体内的传播和疾病的临床演变中发挥作用。
The ongoing pandemic due to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has so far infected about 2.42 × 107 (as at 27 August 2020) subjects with more than 820,000 deaths. It is the third zoonotic coronavirus-dependent outbreak in the last twenty years and represents a major infective threat for public health worldwide. A main aspect of the infection, in analogy to other viral infections, is the so-called “cytokine storm”, an inappropriate molecular response to virus spread which plays major roles in tissue and organ damage. Immunological therapies, including vaccines and humanized monoclonal antibodies, have been proposed as major strategies for prevention and treatment of the disease. Accordingly, a detailed mechanistic knowledge of the molecular events with which the virus infects cells and induces an immunological response appears necessary. In this review, we will report details of the initial process of SARS-CoV-2 cellular entry with major emphasis on the maturation of the spike protein. Then, a particular focus will be devoted to describe the possible mechanisms by which dendritic cells, a major cellular component of innate and adaptive immune responses, may play a role in the spread of the virus in the human body and in the clinical evolution of the disease.
