Human fibroblasts represent the most extensively used cell type for the investigation of lytic human cytomegalovirus (HCMV) replication. However, analyzing the function of specific proteins during infection can be challenging since primary cells are difficult to transfect. An alternative approach is the use of lentiviral transduction with vectors for stable or inducible shRNA expression. This approach provides a versatile tool to study the role of host cell factors during HCMV infection. The essential steps to achieve an efficient target protein knockdown are shRNA design, cloning, generation of transgenic lentiviral particles, and, finally, transduction of the cells. However, these steps are highly dependent on the selected vector system. Here we focus on two different vector systems and describe how to successfully generate stable and inducible knockdown fibroblasts. Additionally, we demonstrate different methods to validate the knockdown of the target protein. |
