Abstract: The invention provides pluripotent cells that are used therapeutically for regenerating tissues but avoid rejection by subjects that receive them. In particular, the invention provides hypo-immunogenic pluripotent cells that avoid host immune rejection. The cells lack major immune antigens that trigger immune responses and are engineered to avoid phagocytic endocytosis. The invention further provides universally acceptable “off-the-shelf” pluripotent cells and derivatives thereof for generating or regenerating specific tissues and organs.

Abstract: Disclosed herein are cells including neural cells that evade immune recognition such as microglial response and related methods of their use and generation. In some embodiments, the cells disclosed herein have reduced levels or activities of MHC I and/ or MHC II human leukocyte antigens, and in some instances, exogenously express CD47. In some embodiments, the cells are derived from pluripotent stem cells that evade immune recognition by a recipient subject.

Abstract: Disclosed herein are hypoimmunogenic cells for administering to a sensitized patient. In some instances, the patient is sensitized from a previous pregnancy or a previous transplant. In some embodiments, the cells exogenously express CD47 proteins and exhibit reduced expression of MHC class I proteins, MHC class II proteins, or both.

Abstract: Provided herein are cells with a gene modification of an ABO gene, RHD gene, and/or FUT1 gene. In some embodiments, the cells express reduced levels of a MHC I antigen and/or a MHC II antigen. In some instances, the cells are also hypoimmunogenic cells.

Abstract: Disclosed herein are methods of treating a disorder in a patient by administering immune evading cells. In some embodiments, the patient receives more than one administration of such cells. In some embodiments, the cells disclosed herein have reduced levels or activities of MHC I and/or MHC II human leukocyte antigens. In some embodiments, the cells are derived from primary T cells or pluripotent stem cells that evade immune recognition. In some embodiments, the cells comprise a chimeric antigen receptor.

Abstract: Disclosed herein are cells including cells expressing CD24 and related methods of their use and generation. In some embodiments, the cells disclosed herein do not express one or more MHC I and/or MHC II human leukocyte antigens. In some embodiments, the cells are hypoimmunogenic.

Abstract: The invention discloses for the first time pluripotent cells, including induced pluripotent stem cells, embryonic stem cells, and hypo-immune pluripotent cells that are ABO blood type O Rhesus Factor negative and evade rejection resulting from blood type antigen mismatch. The invention further provides universally acceptable “off-the-shelf” pluripotent cells and derivatives thereof for generating or regenerating specific tissues and organs.

Abstract: The invention discloses for the first time pluripotent cells, including hypoimmune pluripotent ABO blood type O Rhesus Factor negative (HIPO?) cells, that evade rejection by the host allogeneic immune system and avoid blood antigen type rejection. The HIPO? cells comprise reduced HLA-I and HLA-II expression, increased CD47 expression, and a universal blood group O Rh? (“O?”) blood type. The universal blood type is achieved by eliminating ABO blood group A and B antigents as well as eliminating Rh factor expression, or by starting with an O? parent cell line. These new, novel HIPO? cells evade host immune rejection because they have an impaired antigen presentation capacity, protection from innate immune clearance, and lack blood group rejection. The cells of the invention also include O? pluripotent stem cells (iPSCO?) and O? embryonic stem cells (ESCO?).
