Naturally Occurring Capsid Substitutions Render HIV-1 Cyclophilin A Independent in Human Cells and TRIM-cyclophilin-resistant in Owl Monkey Cells

Abstract excerpt

In this study, we asked if a naturally occurring HIV-1 variant exists that circumvents CypA dependence in human cells. To address this issue, we sought viruses for CypA independence using Debio-025, a cyclosporine A (CsA) analog that disrupts CypA-capsid interaction. Surprisingly, viral variants from the Main group replicate even in the presence of the drug. Sequencing analyses revealed that these viruses encode...
