Identification of a small molecule for enhancing lentiviral transduction of T cells

High-throughput screening identified a small molecule, GSK2622391, that enhances lentiviral transduction efficiency in T cells. The compound improves vector copy number without negatively impacting cell viability or function. G-Rex plates were used for T cell expansion during small-scale validation experiments.
