Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) pandemic has affected millions of people worldwide. The pathophysiology of this virus is not very clearly known, thus, enormous efforts are being made by the scientific community to delineate its evading mechanism. In this review, we have summarized the hyperinflammation and humoral and cell-mediated immune response generated in human body after infection with the SARS-CoV-2 virus. The inflammatory response generated after infection by increased proinflammatory cytokines and chemokines, and complement proteins activation may likely contribute to disease severity. We also discussed the other factors that may affect immunity and could be important comorbidities in the disease severity and outcome.
严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)可引起 2019 年冠状病毒病(COVID-19)大流行,已影响全球数百万人。该病毒的病理生理学尚不清楚,因此科学界正在做出巨大努力来阐明其逃避机制。在这篇综述中,我们总结了人体感染 SARS-CoV-2 病毒后产生的过度炎症反应以及体液和细胞介导的免疫反应。感染后产生的炎症反应可能与疾病的严重程度有关,其由促炎细胞因子和趋化因子增加以及补体蛋白激活引起。我们还讨论了可能影响免疫的其他因素,这些因素可能是疾病严重程度和结果的重要合并症。
