This study characterizes the antigenic properties and infectivity of the SARS-CoV-2 BA.2.86 variant, finding it evades immune responses but has reduced infectivity compared to previous variants.

Convergent evolution of SARS-CoV-2 XBB lineages on receptor-binding domain 455-456 synergistically enhances antibody evasion and ACE2 binding

This study shows that convergent evolution of SARS-CoV-2 XBB lineages at RBD positions 455-456 synergistically enhances antibody evasion and ACE2 binding through epistatic interactions.

Repeated Omicron exposures override ancestral SARS-CoV-2 immune imprinting

This study shows repeated Omicron exposures reduce immune imprinting from wildtype vaccines, leading to higher neutralizing antibodies against XBB variants.

Underlying driving forces of the SARS-CoV-2 evolution: immune evasion and ACE2 binding affinity

This study analyzes SARS-CoV-2 mutations across all open-access genomes to determine their impact on immune evasion and ACE2 binding affinity, revealing distinct evolutionary patterns.

Enhanced transmissibility of XBB.1.5 is contributed by both strong ACE2 binding and antibody evasion

This study shows XBB.1.5 has higher ACE2 binding and moderate antibody evasion, contributing to its increased transmissibility compared to other variants.

Imprinted SARS-CoV-2 humoral immunity induces convergent Omicron RBD evolution

The paper shows that convergent evolution of Omicron variants evades antibodies from BA.5 infections while maintaining ACE2 binding, driven by immune imprinting.

Further humoral immunity evasion of emerging SARS-CoV-2 BA.4 and BA.5 subvariants

This study shows that BA.4.6, BA.4.7, and BA.5.9 subvariants with R346 mutations evade humoral immunity more effectively than BA.4/BA.5, reducing neutralization titers by 1.5-2.6-fold.

Rational identification of potent and broad sarbecovirus-neutralizing antibody cocktails from SARS convalescents
