Abstract Disruption of cyclophilin A (CypA)-capsid interactions affects HIV-1 replication in human lymphocytes. To understand this mechanism, we utilize human Jurkat cells, peripheral blood mononuclear cells (PBMCs), and CD4(+) T cells. Our results show that inhibition of HIV-1 infection caused by disrupting CypA-capsid interactions is dependent on human tripartite motif 5alpha (TRIM5alpha(hu)), showing that TRIM5alpha(hu) restricts HIV-1 in CD4(+) T cells. Accordingly, depletion of TRIM5alpha(hu) in CD4(+) T cells rescues HIV-1 that fail to interact with CypA, such as HIV-1-P90A. We found that TRIM5alpha(hu) binds to the HIV-1 core. Disruption of CypA-capsid interactions fail to affect HIV-1-A92E/G94D infection, correlating with the loss of TRIM5alpha(hu) binding to HIV-1-A92E/G94D cores. Disruption of CypA-capsid interactions in primary cells has a greater inhibitory effect on HIV-1 when compared to Jurkat cells. Consistent with TRIM5alpha restriction, disruption of CypA-capsid interactions in CD4(+) T cells inhibits reverse transcription. Overall, our results reveal that CypA binding to the core protects HIV-1 from TRIM5alpha(hu) restriction.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
