Abstract

Delivering small hairpin RNAs (shRNAs) and the HIV-1 virus to primary CD4+ T cells with high transduction efficiency and high cell viability can be challenging. Here, we present a flow cytometry-based assay to knock down the host protein SMYD5 by shRNA and study the HIV-1 virus specifically in shRNA-containing cells. We describe steps for purifying CD4+ T cells, activating them with CD3/CD28 Dynabeads, transfection of plasmids into HEK293T cells, spinoculation with two different viruses, and analysis by flow cytometry. For complete details on the use and execution of this protocol, please refer to Boehm et al.1.
