COVID-19 caused by the novel coronavirus, severe acute respiratory syndrome coronavirus 2, (SARS-CoV-2) is a highly contagious disease known for its significant lung damage. Although the impact of the COVID-19 pandemic on our daily lives has been limited, the virus has not vanished entirely and continues to undergo mutations. This calls for a concentrated focus on the matter of SARS-CoV-2 immune evasion. Drawing on observations of immune escape mechanisms in other viruses, some scholars have proposed that liquid-liquid phase separation might play a crucial role in SARS-CoV-2's ability to evade the immune system. Within the structure of SARS-CoV-2, the nucleocapsid protein plays a pivotal role in RNA replication and transcription. Concurrently, this protein can engage in phase separation with RNA. A thorough examination of the phase separation related to the nucleocapsid protein may unveil the mechanism by which SARS-CoV-2 accomplishes immune evasion. Moreover, this analysis may provide valuable insights for future development of innovative antiviral drugs or vaccines.
由新型冠状病毒（SARS-CoV-2）引起的 COVID-19 是一种高传染性疾病，其特征是肺部严重损伤。尽管 COVID-19 大流行对我们日常生活的影响有限，但该病毒并未完全消失，仍在不断发生突变。这就要求我们集中精力研究 SARS-CoV-2 的免疫逃避问题。借鉴其他病毒免疫逃逸机制的观察结果，一些学者提出液-液相分离可能在 SARS-CoV-2 逃避免疫系统的能力中发挥关键作用。在 SARS-CoV-2 的结构中，核衣壳蛋白在 RNA 复制和转录中起着关键作用。同时，这种蛋白可以与 RNA 发生相分离。深入研究核衣壳蛋白相关的相分离可能揭示 SARS-CoV-2 实现免疫逃避的机制。此外，该分析可为未来开发创新型抗病毒药物或疫苗提供有价值的见解。
