A Reliable Primary Cell Model for HIV Latency: The QUECEL (Quiescent Effector Cell Latency) Method.
Methods in molecular biology (Clifton, N.J.)(2022)
摘要
One of the main methods to generate the HIV reservoir is during the transition of infected activated effector CD4 T cells to a memory phenotype. The QUECEL (Quiescent Effector Cell Latency) protocol mimics this process efficiently and allows for production of large numbers of latently infected CD4+ T cells. After polarization and expansion, CD4+ T cells are infected with a single round reporter virus which expressed GFP/CD8a. The infected cells are purified and coerced into quiescence using a defined cocktail of cytokines including TGF-β, IL-10, and IL-8, producing a homogeneous population of latently infected cells. Since homogeneous populations of latently infected cells can be recovered, the QUECEL model has an excellent signal-to-noise ratio, and has been extremely consistent and reproducible in numerous experiments performed during the last 5 years. The ease, efficiency, and accurate mimicking of physiological conditions make the QUECEL model a robust and reproducible tool to study the molecular mechanisms underlying HIV latency.
