摘要:
The disclosure provides a chimeric antigen receptor (CAR) comprising a modified hinge, transmembrane and/or intracellular domain disclosed herein. Some aspects of the disclosure relate to a polynucleotide encoding a chimeric antigen receptor (CAR) comprising the costimulatory domain disclosed herein. Other aspects of the disclosure relate to cells comprising the CAR and use in a T cell therapy.
摘要:
The present disclosure relates to genetically modified T cells comprising a transgene encoding an engineered antigen specific receptor, wherein expression of an endogenous gene selected from MNKl, MNK2, or both are inhibited in the genetically modified T cell in order to enhance central memory T cell subsets in cellular immunotherapy compositions.
摘要:
The present invention is directed to a chimeric antigen receptor fusion protein comprising from N-terminus to C-terminus: (i) a single-chain variable fragment (scFv) having activity against tumor antigen,(ii) a transmembrane domain, (iii) at least one co-stimulatory domain having one or more binding motifs immediately repeated at least one time, and (iv) an activating domain. A preferred co-stimulatory domain is derived from human CD28, 4-1BB, ICOS-1, CD27, OX-40, GITR, or DAP10.
摘要:
Provided herein are methods of generating antigen-specific T cells for therapeutic administration to a human patient having or suspected of having a pathogen or cancer using a CD34 fraction of an apheresis collection from G-CSF mobilized donors. Also disclosed are methods of treating a human patient using antigen-specific T cells generated by such methods, and methods of assessing antigen-specific T cells for suitability for therapeutic administration to a human patient.
摘要:
Described herein are agents and methods for targeting antigen-specific B cells using engineered T cells, such as regulatory T cells or cytotoxic T cells, or bi-specific antibodies. The agents and methods can be used to reduce undesirable immune responses.
摘要:
Described herein are human antibody agents and multi-specific binding agents that specifically bind human CD 19, in particular, native human CD 19. Also provided herein are methods of using the same or compositions thereof for the detection, prevention and/or therapeutic treatment of diseases characterized by CD 19 expression, in particular, B cell lymphomas and leukemias.
摘要:
Provided herein are methods for delaying or inhibiting T cell maturation or differentiation in vitro for a T cell therapy, comprising contacting one or more T cells from a subject in need of a T cell therapy with an AKT inhibitor and at least one of exogenous Interleukin-7 (IL-7) and exogenous Interleukin-15 (IL-15), wherein the resulting T cells exhibit delayed maturation or differentiation. In some embodiments, the method further comprises administering the one or more T cells to a subject in need of a T cell therapy.
摘要:
The purpose of the present invention is to provide: a detection agent for specifically detecting a cancer stem cell; a tumor antigen peptide specifically presented by cancer stem cells; a medicinal composition useful in preventing and/or treating cancer, said medicinal composition comprising the aforementioned tumor antigen peptide as an active ingredient; a method for screening the tumor antigen peptide; etc. To achieve the abovementioned purpose, provided are: peptides represented by Y0-X0-Z0; a polyepitope peptide consisting of a plurality of epitope peptides connected together, said polyepitope peptide containing at least one of the abovementioned peptides as one of the epitope peptides; a polynucleotide encoding the aforementioned peptides and/or polyepitope peptide; a medicinal composition comprising the same as an active ingredient; a prophylactic and/or therapeutic agent for cancer characterized by inducing CTL; etc.
摘要:
The present invention relates methods for preparing antigen- specific T cells from an umbilical cord blood sample. In particular, the present invention relates to a method for preparing Ag-specific T cells from a CB sample isolated from a subject comprising the steps of i) culturing said CB sample in an appropriate culture medium, which comprises an amount of at least one agent capable of stimulating dendritic cell differentiation and an amount of at least one Ag and ii) isolating said Ag-specific T cells.
摘要:
Disclosed herein are modified primary human T cells and populations thereof comprising a genome in which the CTLA4, PD1, TCRA, TCRB, and/or B2M genes have been edited to generate an off-the-shelf universal CAR T cell from allogeneic healthy donors that can be administered to any patient while reducing or eliminating the risk of immune rejection or graft versus host disease, and which are not prone to T cell inhibition, and methods for allogeneic administration of such cells to reduce the likelihood that the cells will trigger a host immune response when the cells are administered to a subject in need of such cells.
