System for the expression of a protein or of a heterologous gene comprising a recombinant vector, which can be used for the transduction of cells of the hematopoietic line, in particular stem cells, so that said cell thus transduced will not express the protein or the gene heterologous than in mature T cells after selection of the repertoire, said vector being provided with all the sequences necessary for its expression, and characterized in that it contains at least one enhancer of a CD4 gene of the same species or species different. |
