The 2nd preprint from G2P-Japan is out at @biorxivpreprint !
We revealed that the SARS-CoV-2 delta variant (B.1.617.2 lineage) is highly fusogenic and #P681R mutation, a hallmark in the B.1.617 lineage, is its determinant. Please retweet 1/3

In this study, we demonstrated that #P681R mutation in the SARS-CoV-2 spike protein enhances and further accelerates SARS-CoV-2 spike-mediated cell-cell fusion. 2/3
