72 results about "Glypican 3" patented technology

Glypican-3 is a protein that, in humans, is encoded by the GPC3 gene. The GPC3 gene is located on human X chromosome (Xq26) where the most common gene (Isoform 2, GenBank Accession No.: NP_004475) encodes a 70-kDa core protein with 580 amino acids. Three variants have been detected that encode alternatively spliced forms termed Isoforms 1 (NP_001158089), Isoform 3 (NP_001158090) and Isoform 4 (NP_001158091).

The invention relates to the field of tumor cellular immunotherapy, and in particular relates to a recombinant lentivirus and application thereof. The recombinant lentivirus comprises a chimeric antigen receptor, wherein the chimeric antigen receptor mainly comprises signal peptide, an antigen recognition domain, a transmembrane domain, an intracellular co-stimulation signal transduction domain and a CD3 zeta signal transduction domain which are serially connected; the intracellular co-stimulation signal transduction domain mainly comprises a human TLR2 (Toll Like Receptor 2) intracellular domain. A GPC3 CAT T (Glypican 3 CAT T) cell prepared from the recombinant lentivirus has an intense cell killing effect on liver cancer cells, a Th1 cell factor can be highly expressed, a tumor killing effect caused by non-CAR T (Chimeric Antigen Receptor T) cell can be stimulated to the maximum extent, escape and potential reoccurrence risk of GPC 3-tumor cells can be effectively prevented, the tumor cells can be killed by T cells expressing the chimeric antigen receptor, normal tissue can be slightly damaged, a tumor immunosuppression micro environment can be broken through, and thus a relatively good treatment effect on solid tumor can be achieved.
