Cell surface CD4 downregulation and resistance to superinfection induced by a defective provirus of HIV-1.

abstract：:Clade 2.3.4.4 H5N8 highly pathogenic avian influenza viruses (HPAIVs) have spread worldwide. Phylogenetic analysis identified two genetic groups of the H5N8 HPAIVs in South Korea; group A evolved further into four subgroups.
