Abstract: The present invention relates to a genetically modified hematopoietic stem cell comprising, in at least one globin gene comprised in the genome thereof, at least one transgene encoding a therapeutic protein or a therapeutic ribonucleic acid, the said transgene being placed under the control of the endogenous promoter of the said globin gene.

Abstract: The present invention relates to an expression system for systemic administration comprising a sequence encoding a protein, said expression system allowing: the expression at a therapeutically acceptable level of the protein in the target tissues including skeletal muscles; and the expression at toxically acceptable level of the protein in tissues other than the target tissues, especially in the heart.

Abstract: The present invention relates to compositions and methods, in particular to methods based on systemic injection of rAAV, for delivering genes to cells of the central nervous system in mammals, such as brain neurons or glial cells, and in particular to motor neurons or glial cells of the spinal cord The invention also relates to methods of treating motor neuron disorders in mammals by expression of therapeutic genes. The invention stems from the unexpected discovery that peripheral injection of AAV vectors leads to a bypass of the blood brain barrier and a massive infection of motor neurons. The invention may be used in any mammal, including human subjects.
