Biological features of novel avian influenza A (H7N9) virus
Jianfang Zhou, Dayan Wang, Rongbao Gao, Baihui Zhao, Jingdong Song+ et al.
An initial characterization of the receptor-binding properties of the novel avian influenza A (H7N9) shows that the virus has acquired the ability to bind human receptors while retaining the ability to bind avian receptors; the virus infects epithelial cells in the human lower respiratory tract and type II pneumocytes in the alveoli, and hypercytokinaemia was seen in infected patients.
