Omicron是最新的SARS-CoV-2关注变种(VOC),它在尖峰蛋白中存在多种突变,这在以前的VOC中没有观察到。初步研究表明,奥美康可显著降低疫苗和既往感染诱导的抗体的中和能力。然而,它对T细胞反应的影响仍有待确定。在这里,我们评估Omicron突变对已知T细胞表位的影响,并报告数据表明,T细胞对这种新变体的反应保持广泛的强健。
Omicron, the most recent SARS-CoV-2 variant of concern (VOC), harbours multiple mutations in the spike protein that were not observed in previous VOCs. Initial studies suggest Omicron to substantially reduce the neutralizing capability of antibodies induced from vaccines and previous infection. However, its effect on T cell responses remains to be determined. Here, we assess the effect of Omicron mutations on known T cell epitopes and report data suggesting T cell responses to remain broadly robust against this new variant.
