CD8+ T lymphocytes can recognize and eliminate cells infected by viruses. However, the human immunodeficiency virus (HIV-1) has developed mechanisms to evade CD8+ T-cell-mediated clearance. Here, we describe a protocol to assess the role of the HIV-1 protein Nef in immune evasion. The viral competition assay reveals the preferential killing of HIV-1-infected cells unable to express Nef. This methodology can be extended to study HIV-1 proteins involved in immune evasion and viral variants encoding cytotoxic T lymphocyte escape mutations. For complete details on the use and execution of this protocol, please refer to Duette et al. (2022). The viral competition assay reveals the role of the viral protein Nef in immune escape From genomic DNA to sequencing-ready libraries in approximately one day Less than 1 × 107 PBMCs are required to perform the viral competition assay Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
