It has been suggested that SARS-CoV-2 NTD might be bid to ABO(H) blood antigens, because SARS-CoV-2 RBD shares sequence similarity with a galectin family. Authors have confirmed that SARS-CoV-2 RBD could bind to A blood type I antigen expressed on respiratory epithelium cells with using glycan arrays.
