Successful gene transfer into T lymphocytes would provide a useful therapeutic modality for the treatment of various diseases and a valuable way to study T cell functions. Currently, most protocols involving gene transfer into T lymphocytes utilize amphotropic retroviral vectors. However, transduction efficiency using these vectors is relatively low because of the high proportion of resting cells, the concentration-dependent growth manner of T lymphocytes, and the low titer of retroviral vectors. In this article we define conditions that provide high levels of transduction by using IL-2 prestimulation and LipofectAMINE for both mouse and human T lymphocytes. We compared the effects of IL-2 prestimulation on transduction efficiencies at different time points and achieved maximum transfer levels at 72 hr after the incubation. By combining the best prestimulation time and cationic lipids-LipofectAMINE at a dose of 0.8 microM, the transduction efficiencies were increased to 45-75% (62.3 +/- 4.3%) in human T lymphocytes and to 21-33% (27 +/- 1.42%) in murine T lymphocytes as determine by FDG staining and X-Gal visualization, compared with 5% with conventional methods. These results indicate that transduction efficiencies in T lymphocytes can be significantly improved by a prolonged preincubation with IL-2 and by the addition of LipofectAMINE.
