  • Publication number: 20260027159
    Abstract: The present invention relates to a pharmaceutical composition and a cell therapy agent for preventing or treating a neurological disease, comprising Schwann cell precursors (SCPs) prepared from pluripotent stem cells (PSCs) or somatic cells, or Schwann cells (SCs) differentiated therefrom; and natural killer (NK) cells as active ingredients. Specifically, the present invention is characterized in that the SCPs express one or more selected from the group consisting of GAP43, SOX10, IGFBP2, and a combination thereof; the SCs express one or more selected from the group consisting of S100B, SOX10, and a combination thereof; and the NK cells express one or more selected from the group consisting of CD56+, CD16+, and a combination thereof.

  • Patent number: 12435117
    Abstract: The present invention relates to: a method for producing immunocytes, specifically induced natural killer T (iNKT) cells that are induced by direct reprogramming of isolated somatic cells, and chimeric antigen receptor (CAR)-iNKT cells into which a CAR gene encoding a CAR is introduced; iNKT cells produced by the method; and a cell therapy composition and a pharmaceutical composition for preventing or treating cancer, comprising the iNKT cells. The method according to the present invention can produce, through direct reprogramming, iNKT cells or iNKT cells into which a CAR gene is introduced, from isolated cells so as to simplify the production process and shorten production time, thereby reducing costs, to have excellent NKT cell production efficiency, and to ensure safety according to the production without passing through induced pluripotent stem cells, thereby having an excellent NKT cell production effect distinguished from that of a conventional reprogramming technique.

  • Publication number: 20240318139
    Abstract: The present invention relates to a method for preparing directly reprogrammed natural killer (drNK) cells or CAR (chimeric antigen receptor) gene introduced CAR-drNK cells using substances and methods that inhibit BCL11B (B-cell leukemia 11B) gene expression and/or function. The present invention also relates to drNK cells or CAR-drNK cells prepared by a BCL11B gene-based cell reprogramming method, and a cell therapeutic and/or a composition for the prevention or treatment of cancer diseases and infectious diseases caused by viruses, bacteria, fungi, and the like, and/or inflammatory diseases, which contain the cells.

  • Publication number: 20220184128
    Abstract: The present invention relates to a method for producing induced natural killer (iNK) cells, into which a chimeric antigen receptor (CAR) gene encoding a CAR is introduced, iNK cells produced by the method, and a cell therapy composition and a pharmaceutical composition for preventing or treating cancer, comprising the iNK cells. The method according to the present invention has the effects of producing the iNK cells, into which a CAR gene is introduced, with high efficiency through direct reprogramming from isolated cells without limiting an initial cell, and directly producing the same without a differentiation process, thereby simplifying the production process and reducing costs and time. The method according to the present invention has the effect of producing excellent NK cells having enhanced safety by directly producing NK cells from human somatic cells that are easy to obtain, without passing through induced pluripotent stem cells produced through conventional reprogramming technology.

  • Patent number: 10035830
    Abstract: The present invention relates to a method for preparing a GM1 gangliosidosis human cell model based on induced pluripotent stem cells (iPSCs) and iPSCs originated neural progenitor cells, and a use of the GM1 model above for the development of a GM1 gangliosidosis treating agent. The iPSCs originated from GM1 patient fibroblasts can be differentiated into neural progenitor cells (NPCs) and neurosphere cells that can emulate the characteristics shown in GM1 patient, so that the said cells can be efficiently used for the investigation of intracellular GM1 symptoms such as the GM1 gangliosidosis and lysosome accumulation and the gene expression pattern change. So, the GM1 cell model of the present invention can be efficiently used for the study of GM1 development mechanism and the study for the development of a therapeutic agent for the disease.
