In contrast to murine leukaemia virus (MLV)-derived vector systems, vector particles derived from the avian spleen necrosis virus (SNV) have been successfully targeted to subsets of human cells by envelope modification with antibody fragments (scFv). However, an in vivo application of the SNV vector system in gene transfer protocols is hampered by its lack of resistance against human complement. To overcome this limitation we established pseudotyping of MLV vector particles produced in human packaging cell lines with the SNV envelope (Env) protein. Three variants of SNV Env proteins differing in the length of their cytoplasmic domains were all efficiently incorporated into MLV core particles. These pseudotype particles infected the SNV permissive cell line D17 at titers of up to 10(5) IU/ml. A stable packaging cell line (MS4) of human origin released MLV(SNV) pseudotype vectors that were resistant against human complement inactivation. To redirect their tropism to human T cells, MS4 cells were transfected with the expression gene encoding the scFv 7A5 in fusion with the transmembrane domain (TM) of the SNV Env protein, previously shown to retarget SNV vector particles to human lymphocytes. MLV(SNV-7A5)-vector particles released from these cells were selectively infectious for human T cell lines. The data provide a proof of principle for targeting MLV-derived vectors to subpopulations of human cells through pseudotyping with SNV targeting envelopes.
