that both HAT and TMPRSS2 are coexpressed with 2,6-linked sialic acids , the major receptor determinant of human influenza viruses , throughout the human respiratory tract .
that TMPRSS2 and HAT are expressed by important influenza and SARS - coronavirus target cells
Here , we show that both HAT and TMPRSS2 are coexpressed with 2,6-linked sialic acids , the major receptor determinant of human influenza viruses , throughout the human respiratory tract .
In sum , our results show that TMPRSS2 and HAT are expressed by important influenza and SARS - coronavirus target cells and could thus support viral spread in the human host .
