CRISPR-BASED FOXP3 GENE ENGINEERED T CELLS AND HEMATOPOIETIC STEM CELL PRECURSORS TO TREAT IPEX SYNDROME PATIENTS

摘要

Compositions and methods are provided relating to FOXP3 gene edited hematopoietic cells, include hematopoietic stem and progenitor cells, lymphoid progenitor cells, and CD4+ T cells. The gene edited cells are useful in cellular therapy to restore normal immune functions and promote immune tolerance. In particular, CD4^edFOXP3 T cells, which may be differentiated from FOXP3 gene edited hematopoietic progenitor cells, can physiologically express functional FOXP3 and exert normal immune responses as effector T cells or have immune suppressive characteristics as naturally occurring Treg cells.
