由 SARS-CoV-2 引起的疾病 COVID-19 出现一年多后,继续困扰着世界并主宰我们的日常生活。尽管已经开发出有效的疫苗,但随着来自英国、南非、巴西和加利福尼亚州的主要新变种的发现,这种冠状病毒大流行继续引起人们的关注。再加上对导致人类感染的独特水貂品系以及进一步突变的可能性的担忧,SARS-CoV-2 变体引发了人们对疫苗和自然感染免疫力的传播和逃避的担忧。在这里,我们概述了驱动 SARS-CoV-2 变异进化的因素,探索特定突变的潜在影响,检查进一步突变的风险,并考虑了解这些变异造成的威胁所需的实验研究。在这篇评论中,Plante 等人。检查 SARS-CoV-2 变体,包括 B.1.1.7(英国)、B.1.351(RSA)、P.1(巴西)和 B.1.429(加利福尼亚)。他们重点关注哪些因素导致变异的出现、刺突蛋白内外的突变,以及了解变异对感染、传播和疫苗功效的影响所需的研究。
More than a year after its emergence, COVID-19, the disease caused by SARS-CoV-2, continues to plague the world and dominate our daily lives. Even with the development of effective vaccines, this coronavirus pandemic continues to cause a fervor with the identification of major new variants hailing from the United Kingdom, South Africa, Brazil, and California. Coupled with worries over a distinct mink strain that has caused human infections and potential for further mutations, SARS-CoV-2 variants bring concerns for increased spread and escape from both vaccine and natural infection immunity. Here, we outline factors driving SARS-CoV-2 variant evolution, explore the potential impact of specific mutations, examine the risk of further mutations, and consider the experimental studies needed to understand the threat these variants pose. In this review, Plante et al. examine SARS-CoV-2 variants including B.1.1.7 (UK), B.1.351 (RSA), P.1 (Brazil), and B.1.429 (California). They focus on what factors contribute to variant emergence, mutations in and outside the spike protein, and studies needed to understand the impact of variants on infection, transmission, and vaccine efficacy.
