  • Publication number: 20240350542
    Abstract: The present invention relates to an anticancer T cell therapy product-assisting composition comprising a depleting anti-CD4 monoclonal antibody and a use thereof. Accordingly, the composition comprising a depleting anti-CD4 monoclonal antibody according to the present invention is able to maximize the anticancer effect of a cancer antigen-specific anticancer T cell therapy product by maintaining an immunodeficient state and is thus effective. In addition, when administered twice or more times at regular intervals of 5 to 8 days, the composition exhibits a far superior effect.

  • Publication number: 20230072119
    Abstract: The present invention relates to a method for isolation of autologous cancer antigen-specific CD8 T cell by using CD71 and uses thereof. In case of isolating autologous cancer antigen-reactive CD8 T cells using the isolation method of the present invention, it is possible to provide significant anticancer effects by amplifying a large amount of CD8 T cells even with less blood since CD8 T cells responding to various cancer antigens in addition to CD8 T cells specific for autologous cancer antigen are also separated. Therefore, it can be effectively used for immunotherapy that induces temporary immunodeficiency for treatment such as adoptive cell therapy.

  • Publication number: 20220349895
    Abstract: The present invention relates to an apparatus for diagnosing solid cancers comprising lung cancer, pancreatic cancer, bile duct cancer, colorectal cancer, breast cancer, gastric cancer, brain tumors, kidney cancer, liver cancer, and cervical cancer. More specifically, the apparatus comprises: a concentration measurement unit for measuring the concentration of each of acyl-carnitine (AC), nudifloramide (2PY), and lysophosphatidylcholine (LPC) from a biological sample; a pre-processing unit for pre-processing the measured concentrations; and a diagnosis unit for determining the diagnosis information of cancer through linear discriminant analysis using the pre-processed concentrations.

  • Patent number: 10801011
    Abstract: Provided is a method for isolating and proliferating autologous cancer antigen-specific CD8+T cells, and more particularly, a method for selecting an epitope recognized by CD8+ T cells from autologous cancer antigens present in blood of individual cancer patients; and isolating autologous cancer antigen-specific CD8+ T cells by using a peptide of the selected epitope, and a method of massively proliferating CD8+ T cells by using the method. According to the present invention, it is possible to isolate autologous cancer antigen-specific CD8+ T cells by using the peptide of the CD8 T cell epitope of the autologous cancer antigen present in blood of individual cancer patients instead of a heterologous antigen. Therefore, by using T cells recognizing the autologous cancer antigen, it is possible to effectively select and eliminate cancer cells derived from the cancer patient's own cells. Thus, T cells can be applied to treatment and alleviation of cancer diseases without side effects.
