Antibodies against epitopes in S1 give the most accurate CoP against infection by the SARS-CoV-2 coronavirus. Measurement of those antibodies by neutralization or binding assays both have predictive value, with binding antibody titers giving the highest statistical correlation. However, the protective functions of antibodies are multiple. Antibodies with multiple functions other than neutralization influence efficacy. The role of cellular responses can be discerned with respect to CD4 T cells and their augmentation of antibodies, and with respect to CD8 cells with regard to control of viral replication, particularly in the presence of insufficient antibody. More information is needed on mucosal responses.
针对 S1 表位的抗体对感染 SARS-CoV-2 冠状病毒提供了最准确的保护作用。通过中和或结合测定法测量这些抗体都具有预测价值,其中结合抗体滴度具有最高的统计学相关性。然而,抗体的保护功能是多方面的。除中和作用以外具有多种功能的抗体影响疗效。可以从 CD4 T 细胞及其对抗体的增强作用以及 CD8 细胞对病毒复制的控制作用方面来识别细胞反应的作用,特别是在抗体不足的情况下。还需要更多关于黏膜反应的信息。
