Preprint: L452R mutation increases Omicron variant fusogenicity and infectivity

Here, we developed an L452R mutated Omicron variant (Omicron-L452R) and found that the Omicron-L452R variant rescued fusogenicity and strengthened the high infectivity by enhancing the cleavage of the spike protein. More...

Preprint: SARS-CoV-2 Omicron – multiple inter-variant recombination events

“By analyzing sequences from a large number of Omicron subvariants, we identified diverse recombination events between two Omicron subvariants and several SARS-CoV-2 variants, suggesting that co-infection and subsequent genome recombination play important roles in the on-going evolution of SARS-CoV-2.
