CAR-T cell for treating AIDS-associated lymphoma, and preparation method and application thereof
PendingCN107904259ALow storm riskSmall storm riskGenetically modified cellsAntiviralsAIDS-related lymphomaCord blood stem cell
The invention discloses a preparation method of a CAR-T cell for treating AIDS-related lymphoma. A CD8+ T cell is used to produce the CAR-T cell, and the CD8-T cell derives from a cord blood T cell. The method includes the following steps: preparing cord blood mononuclear cells from cord blood, removing tumors and other cells by using a human T cell purification kit to obtain T cells, and carryingout separation by using magnetic beads to obtain the CD8+ T cell; activating the CD8+ T cell by using an appropriate medium and appropriate stimulation conditions; transferring CAR to the CD8+ T cellby using lentivirus to prepare the CAR-T cell; and amplifying the CAR-T cell in vitro by using cytokines and activating stimulators to achieve the desired effective dose. The invention also relates to the CAR-T cell prepared by the method, and an application thereof. The CAR-T cell prepared in the invention has a good cell activity and a high proliferation speed, and reduces the attack risk of GVHD; and only the CD8+T cell of the umbilical blood T cells of AIDS patients is used to prepare the CAR-T cell for, so the risk of input CAR-T infected with in-vivo HIV is reduced.
