II型跨膜丝氨酸蛋白酶TMPRSS 2和HAT在细胞培养物中活化流感病毒和SARS冠状病毒(TMPRSS 2),并且可能在感染宿主中的病毒传播和发病机制中起重要作用。然而,目前在很大程度上不清楚这些蛋白酶在人体组织中的病毒靶细胞中表达到何种程度。在这里,我们表明,HAT和TMPRSS 2与2,6-连接的唾液酸,人流感病毒的主要受体决定簇,在整个人类呼吸道共表达。同样,ACE 2,SARS冠状病毒受体,和TMPRSS 2的共表达经常被发现在上,下呼吸消化道,除了声带,会厌和气管。最后,流感病毒的激活在人、禽和猪TMPRSS 2之间是保守的,这表明这种蛋白酶可能激活储存宿主、中间宿主和人宿主中的流感病毒。总之,我们的研究结果表明,TMPRSS 2和HAT由重要的流感和SARS冠状病毒靶细胞表达,因此可以支持病毒在人类宿主中的传播。
The type II transmembrane serine proteases TMPRSS2 and HAT activate influenza viruses and the SARS-coronavirus (TMPRSS2) in cell culture and may play an important role in viral spread and pathogenesis in the infected host. However, it is at present largely unclear to what extent these proteases are expressed in viral target cells in human tissues. 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. Similarly, coexpression of ACE2, the SARS-coronavirus receptor, and TMPRSS2 was frequently found in the upper and lower aerodigestive tract, with the exception of the vocal folds, epiglottis and trachea. Finally, activation of influenza virus was conserved between human, avian and porcine TMPRSS2, suggesting that this protease might activate influenza virus in reservoir-, intermediate- and human hosts. 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.
