Adenoviruses are currently used in a variety of bench and bedside applications. However, their employment in gene delivery to lymphocyte lineages is hampered by the lack of coxsackie virus and adenovirus receptor (CAR) on the cell surface. Exploitation of an alternative receptor on the surface of T lymphocytes can allow for utilization of adenovirus in a variety of T lymphocyte-based diseases and therapies. Here, we describe how resistance to infection can be overcome by the utilization of a bi-specific fusion protein, soluble CAR murine interleukin 2 (sCAR-mIL-2), that retargets adenovirus to the murine IL-2 receptor (IL-2R). Infection of a murine T-cell line, CTLL-2, with a sCAR-mIL-2/Adenovirus conjugate provided a ninefold increase in both green fluorescence protein-positive cells and luciferase expression. In addition, this increase in infection was also seen in isolated primary murine T lymphocytes. In this context, the sCAR-mIL-2 adapter provided a fourfold gene transduction increase in activated primary murine T lymphocytes. Our results show that recombinant sCAR-mIL-2 fusion protein promotes IL-2R-targeted gene transfer to murine T lymphocytes and that alternative targeting can abrogate their native resistance to infection.
