摘要:
Provided is a genetically engineered γδT cell, which is characterized in that a high-affinity αβTCR gene is transferred into the γδT cell, and the affinity of the high-affinity αβTCR to the specific pMHC thereof is at least two times of that of a wild-type αβTCR corresponding thereto. Further provided are a use of and a preparation method for the γδT cell.
摘要:
Provided is a method for genetically editing an enhancer locus of hematopoietic stem cell BCL11A, comprising: disrupting the CTTCCT region of a BCL11A genome by gene editing technology. The genetically edited hematopoietic stem cells have normal cell functions and can significantly increase the expression of fetal hemoglobin, thereby being used for the treatment of β thalassemia and sickle cell anemia.
摘要:
The invention features compositions comprising in vitro generated beta cells capable of glucose-stimulated insulin secretion, methods of inducing beta cell maturation from embryonic or induced pluripotent stem cell-derived beta-like cells, and methods of using in vitro generated beta cells for treatment of type 1 diabetes, type 2 diabetes, or a related disorder.
摘要:
Provided are pharmaceutical compositions comprising an engineered mammalian cell comprising a heterologous nucleic acid encoding an immunomodulator. Further provided are methods of treating cancer using the pharmaceutical composition either singly or in combination with other technologies, such as Chimeric Antigen Receptor (CAR) or recombinant T cell receptor (TCR) modified T cell immunotherapy.
摘要:
A genetically modified cell (e.g., stem cell) containing a complete or partial gene deletion of one or more genes of a blood group antigen (BGA) biosynthesis or transportation pathway is provided. The systems and methods provided herein facilitate the generation of blood substitutes (e.g., blood cells).
摘要:
The present invention is based on applicants' discovery, disclosed herein, of agonists for the TAS2R receptors TAS2R1, TAS2R4, TAS2R9, TAS2R13, TAS2R14, TAS2R16, TAS2R38, TAS2R39, TAS2R44, TAS2R46, and TAS2R60. The assignment of agonists to these receptors makes assays for identifying compounds that modulate bitter taste possible. For example, the present invention provides methods of identifying compounds that inhibit the bitter taste due to these agonists. The present invention also provides methods of identifying compounds that selectively inhibit the bitter taste due to these agonists. The present invention further provides methods of identifying compounds that mimic the bitter taste due these agonists. The present invention also provides methods of identifying compounds that enhance the bitter taste due to these agonists.
