    Abstract: The present invention generally relates to the field of genome engineering (gene editing), and more specifically to gene therapy for the treatment of Severe Combined Immunodeficiency (SCID) related to RAG1. Particularly, the present invention pertains to the treatment of RAG1 deficiency in long-term repopulating hematopoietic stem cells (HSCs). The present invention provides means and methods for genetically modifying HSCs involving gene editing reagents, such as TALE-nucleases, that specifically target a non-functional endogenous RAG1 gene, comprising at least one mutation causing Severe Combined Immunodeficiency (SCID), thereby allowing the restoration of the normal cellular phenotype. The present invention also provides engineered RAG1-edited HSCs comprising an exogenous sequence comprising a nucleic acid sequence encoding a functional RAG1 protein which is integrated in said HSCs' genome into a non-functional RAG1 endogenous locus, resulting in the expression of a functional RAG1 polypeptide. The present invention further provides populations of cells comprising said engineered HSCs, pharmaceutical compositions comprising said engineered HSCs or populations of cells, as well as their use in gene therapy for the treatment of Severe Combined Immunodeficiency (SCID) related to RAG1.

    Abstract: The invention relates to cell death inducing chimeric antigen receptors (D-CAR). In particular, the present invention relates to cell death inducing chimeric antigen receptors which comprise at least one death domain in their endodomain, including cell death inducing chimeric antigen receptors comprising within their death domains modifications which attenuate the self-association and/or binding to pro-apoptotic or pro-necrotic adaptor proteins, such as FADD or TRADD. Moreover, the present invention relates to an engineered immune cell expressing at its surface a cell death inducing CAR of the present invention and, optionally, an activating chimeric antigen receptor, wherein the extracellular ligand-binding domains of the cell death inducing CAR and the activating CAR bind to different antigens. The engineered immune cell may furthermore comprise at least one edited (e.g., inactivated) gene selected from TCR genes, immune check point genes, genes involved in drug resistance, and combinations thereof.
