Abstract
Since its emergence at the end of 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused the infection of more than 600 million people worldwide and has significant damage to global medical, economic, and political structures. Currently, a highly mutated variant of concern, SARS-CoV-2 Omicron, has evolved into many different subvariants mainly including BA.1, BA.2, BA.3, BA.4/5, and the recently emerging BA.2.75.2, BA.2.76, BA.4.6, BA.4.7, BA.5.9, BF.7, BQ.1, BQ.1.1, XBB, XBB.1, etc. Mutations in the N-terminal domain (NTD) of the spike protein, such as A67V, G142D, and N212I, alter the antigenic structure of Omicron, while mutations in the spike receptor binding domain (RBD), such as R346K, Q493R, and N501Y, increase the affinity for angiotensin-converting enzyme 2 (ACE2). Both types of mutations greatly increase the capacity of Omicron to evade immunity from neutralizing antibodies, produced by natural infection and/or vaccination. In this review, we systematically assess the immune evasion capacity of SARS-CoV-2, with an emphasis on the neutralizing antibodies generated by different vaccination regimes. Understanding the host antibody response and the evasion strategies employed by SARS-CoV-2 variants will improve our capacity to combat newly emerging Omicron variants.
期刊介绍:
Cytokine & Growth Factor Reviews is a leading publication that focuses on the dynamic fields of growth factor and cytokine research. Our journal offers a platform for authors to disseminate thought-provoking articles such as critical reviews, state-of-the-art reviews, letters to the editor, and meeting reviews.
We aim to cover important breakthroughs in these rapidly evolving areas, providing valuable insights into the multidisciplinary significance of cytokines and growth factors. Our journal spans various domains including signal transduction, cell growth and differentiation, embryonic development, immunology, tumorigenesis, and clinical medicine.
By publishing cutting-edge research and analysis, we aim to influence the way researchers and experts perceive and understand growth factors and cytokines. We encourage novel expressions of ideas and innovative approaches to organizing content, fostering a stimulating environment for knowledge exchange and scientific advancement.
