Research paper on the illuminating the evolutionary and epidemic dynamics of XBB variant of G2P-Japan, co-authored by HiLung members, was published in the journal “Nature Communications” on 16 May.

The G2P-Japan has illuminated that two XBB variants (BJ.1 and BM.1.1.1) acquired high effective reproduction number (epidemic spread capacity) by genetic recombination at the receptor binding domain (RBD) of the spike protein.
This XBB variant emerged around the summer of 2022 is the first documented SARS-CoV-2 variant increasing its fitness through recombination rather than single mutations.

Our iPS cell-derived lung cells were useful for evaluating the infectivity and proliferative potential of this Omicron subvariants.
