Abstract In late 2022, SARS-CoV-2 Omicron subvariants have become highly diversified,
and XBB is spreading rapidly around the world. Our phylogenetic analyses suggested that …

Abstract Omicron BA. 2.86 subvariant differs from Omicron BA. 2 as well as recently
circulating variants by over 30 mutations in the spike protein alone. Here we report on the …

Abstract The SARS-CoV-2 Omicron variant is more immune evasive and less virulent than
other major viral variants that have so far been recognized,,,,,,,,,,–. The Omicron spike (S) …

Recent studies have revealed the unique virological characteristics of Omicron, particularly
those of its spike protein, such as less cleavage efficacy in cells, reduced ACE2 binding …

Summary The SARS-CoV-2 Omicron BA. 2.75 variant emerged in May 2022. BA. 2.75 is a
BA. 2 descendant but is phylogenetically distinct from BA. 5, the currently predominant BA. 2 …

An essential step in the infection life cycle of the severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) is the proteolytic activation of the viral spike (S) protein, which …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remained genetically
stable during the first 3 months of the pandemic, before acquiring a D614G spike mutation …

Background The COVID-19 pandemic has had a devastating impact on the world over the
