Genetic modification of primary airway epithelial cell cultures defines MX1 as a barrier for zoonotic influenza A viruses in the human respiratory epithelium
The antiviral innate immune response is a major species barrier that emerging viruses must overcome to infect and transmit efficiently in new hosts. In humans, the interferon-stimulated MX1 gene encodes the antiviral MX1 protein, which restricts zoonotic influenza A viruses (IAVs). Resistance to MX1 is considered a key...
