First humanoid coronavirus was discovered in the middle of 1960s, the class of viruses are considered to be a huge threat. The first onset of human coronavirus, SARS (SARS-CoV) appeared in 2003 which spanned five continents having lethal effects on human population accompanied by The Middle East Respiratory Syndrome Coronavirus in 2012 with a death rate of 35%. The viruses remain a threat till date and are of serious concern since no vaccine or specified drug therapy has been approbated for treating human coronaviruses. The viruses became a pandemic worldwide with the emergence of Wuhan coronavirus (2019-nCoV). SARS-CoV2 viral manifestation poses a serious human life risk by causing acute lung injury and various respiratory outcomes and has become a global concern. High pathogenicity and transmission rate of the viral strain has become the spotlight of research community throughout the world. With the ongoing studies on viral structure and host interactions, the intricacy of the viral proteome structure and replication cycle proposes a need to explore our understanding of host factors playing role in viral multiplication cycle. This review provides insight into our prevalent perception of coronavirus-host interactions, structure of SARS-CoV2, receptor mediated entry of virus inside the human cells, ongoing clinical trials, drug therapies and treatments that are being used to combat COVID-19 targeting viral fusion, replication and its multiplication.
首例类冠状病毒于 20 世纪 60 年代中期被发现,这类病毒被认为是巨大的威胁。首例人类冠状病毒,严重急性呼吸综合征冠状病毒(SARS-CoV)于 2003 年爆发,席卷五大洲,对人类造成致命影响。2012 年出现了中东呼吸综合征冠状病毒,死亡率为 35%。这些病毒至今仍构成威胁,令人严重关切,因为尚无批准用于治疗人类冠状病毒的疫苗或特定药物疗法。随着 2019 年武汉冠状病毒(2019-nCoV)的出现,该病毒在全球范围内引发大流行。SARS-CoV2 病毒的表现通过引起急性肺损伤和各种呼吸道后果对人类生命构成严重威胁,已成为全球关注的焦点。该病毒株的高致病性和高传播率已成为世界各地研究界的焦点。随着对病毒结构和宿主相互作用的持续研究,病毒蛋白组结构和复制周期的复杂性提出了需要探索我们对在病毒复制周期中起作用的宿主因素的理解。这篇综述深入探讨了我们对冠状病毒-宿主相互作用、SARS-CoV2 的结构、病毒进入人体细胞的受体介导进入、正在进行的临床试验、针对病毒融合、复制及其增殖的 COVID-19 靶向药物疗法和治疗的现有认识。
