  • Patent number: 12668812
    Abstract: IPEX (Immune dysregulation Polyendocrinopathy X linked) syndrome is a primary immunodeficiency caused by mutations in the gene encoding the transcription factor forkhead box P3 (FOXP3), which leads to the loss of function of thymus-derived CD4+CD25+ regulatory T (tTreg) cells. Preclinical and clinical studies suggest that T cell gene therapy approaches designed to selectively restore the repertoire of Treg cells by transfer of wild type FOXP3 gene is a promising potential cure for IPEX. However, there is still a need for a vector that can be used efficiently for the preparation of said Treg cells. The inventors thus compared 6 different lentiviral constructs according to 4 criteria (vector titers, level of transduction of human CD4+ T cells, level of expression of FOXP3 and ?LNGFR genes, degree of correlation between both expression) and selected one construct comprising a bidirectional PGK-EF1a promoter that showed remarkable efficiency.
