Replication Restriction of Influenza A(H5N1) Clade 2.3.4.4b Viruses by Human Immune Factor
CDC ABSTRACT We show that human myxovirus resistance protein 1 (MxA) suppresses replication of highly pathogenic avian influenza A(H5N1) viruses isolated from mammals in vitro and in MxA-transgenic mice. However, H5N1 can evade MxA restriction through replacement of individual viral polymerase complex components from a human-adapted MxA-resistant strain in vitro. Since 2022, clade 2.3.4.4b highly […]
