  • the subject is pretreated with one or more chemotherapeutic agents to deplete lymphocytes prior to receiving the engineered immune cells of the invention.
  • the chemotherapeutic agent is selected from cyclophosphamide, fludarabine, bendamustine, taxanes or combinations thereof, preferably cyclophosphamide, fludarabine or combinations thereof.
  • the masking peptide can mask the extracellular binding domain, preventing it from binding to the targeted antigen, and when the masking peptide is cleaved by, for example, a protease, the extracellular binding domain can be exposed, making it a "normal" CAR structure.
  • Various switch structures known to those skilled in the art can be used in the present invention.
  • the vectors of the present invention include, but are not limited to, plasmids, viruses (eg, retroviruses, lentiviruses, adenoviruses, vaccinia virus, Rous sarcoma virus (RSV, polyoma virus, and adeno-associated virus (AAV)), and the like ), phages, phagemids, cosmids, and artificial chromosomes (including BAC and YAC).

  • allogeneic refers to any material derived from a different animal or different patient of the same species as the individual into which the material is introduced. Two or more individuals are considered allogeneic to each other when the genes at one or more loci are different. In some cases, allogeneic material from individuals of the same species may be genetically different enough for antigenic interactions to occur.

Abstract

La présente invention concerne une cellule immunitaire modifiée exprimant les éléments suivants : (i) une molécule de surface cellulaire reconnaissant spécifiquement un antigène ; et (ii) un XCL2 et/ou XCL1 exogène. La présente invention concerne en outre l'utilisation de la cellule immunitaire modifiée dans le traitement de cancers, d'infections ou de maladies auto-immunes. Par comparaison avec les cellules immunitaires modifiées classiques, la cellule immunitaire modifiée de la présente invention présente une activité de destruction tumorale significativement améliorée.
