Abstract: The present invention relates to modified Cas9 nuclease comprising a substantial part of a Cas9 nuclease and fused thereto at least one substantial part of a dominant negative effector on non-homologous end-joining selected from the group consisting of RNF168, 53BP1, Ku80 and DNA-PK which compete with NHEJ promoting factors and CtIP.

Abstract: The invention pertains to the field of cell therapy and HIV treatments. It provides with highly specific reagents for reducing or inactivating expression of CCR5 in primate and human primary cells, especially under the form of TALE-nucleases. These reagents allow the production of safer primary hematopoietic cells made resistant to HIV, stem cells or differentiated cells, for their infusion into HIV patients.

Abstract: Herein described is a construct for epigenomic modification of genes composed of: (a) a Krüppel-associated box zinc finger protein or homologous, (b) a DNA region capable of binding to the target gene or homologous, (c) a human DNA methyltransferase DNMT3A or homologous and (d) a murine DNA methyltransferase Dnmt3L or homologous, wherein components a), b), c) and d) are linked to each other either directly or via at least one linker. The construct is a designer epigenome modifier that can be used to silence genes coding for a protein in leukocytes that avoids the internalization of HI viruses in immune cells.
