摘要:
Use of an anti-CD28 antibody or a F(ab')2 fragment thereof in the manufacture of a medicament for administration to a population of CD3-activated CD28 T-cells of a patient to promote the production of a cyclosporine resistant lymphokine selected from IL-2, TNF, IFN-gamma and GM-CSF.
摘要:
Un procédé d'immunothérapie stimule la molécule de surface CD28 de cellules T afin d'augmenter la prolifération de cellules T et d'élever les niveaux globaux de lymphokine et/ou d'accroître la production cellulaire de lymphokines TH1 humaines. Le procédé est sélectif pour le déclenchement de réponses immunes induites par des cellules T activées, et stimule la fonction immune même en présence d'immunosuppresseurs.
摘要:
The invention relates to a new method for in vitro expansion of CD4+CD25HighCD127−/LOWfoxP3+Tregs, wherein the process of Treg expansion takes place permanently or temporarily at a temperature below 37° C., optimally at a temperature of 33° C., the isolated Tregs are expanded in SCGM or X-vivo-20 medium supplemented with human serum or with foetal bovine serum, and magnetic beads coated with anti-CD3 and anti-CD28 antibodies at 1:1 (cell:bead) ratio and interleukin-2 are added to the culture.
摘要:
The present invention provides compositions and methods for treating cancer in a human. The invention includes relates to administering a genetically modified T cell to express a CAR wherein the CAR comprises an antigen binding domain, a transmembrane domain, a costimulatory signaling region, and a CD3 zeta signaling domain.
摘要:
The invention is concerned with fusions of dendritic cells and with tumor or cancer cells. Also provided are methods of making and using these cell fusions, including methods of adoptive immunotherapy as well as methods of stimulating anti-tumor immunity using fused cells and anti-CD3/CD28 antibodies.
摘要:
The present disclosure relates to products and methods for activating and/or expanding T cells. Certain embodiments of the present disclosure provide a porous scaffold comprising one or more conjugated T cell stimulatory molecules.
摘要:
Embodiments are described that relate to methods and systems for growing cells in a hollow fiber bioreactor. In embodiments, the cells may be exposed to an activator for activating expansion of the cells. The cells may in embodiments include T cells, and the activator may be in different forms, including, for example, antigen presenting cells or beads functionalized with antibodies.
摘要:
The present invention generally relates to methods of preparing leukocytes, particularly T cells, ex vivo for use in immunotherapy, particularly cancer immunotherapy. More specifically, the invention relates to methods for the preparation of leukocytes exhibiting cytotoxic properties for use in adoptive cell transfer. The invention also relates to cells and compositions including them for cancer immunotherapy. The invention also relates to methods of immunotherapy, particularly cancer immunotherapy. The present invention relates to a method for producing a leukocyte that has an enhanced capacity for killing a target cell, the method including contacting the leukocyte with a PTPN2 inhibitor in conditions for enabling the inhibitor to inactivate PTPN2 in the leukocyte, thereby producing a leukocyte that has an enhanced capacity for killing a target cell. Preferably, the leukocyte is contacted with the PTPN2 inhibitor in the absence of a T helper cell.
摘要:
The present invention provides immunoresponsive cells, including T cells, cytotoxic T cells, regulatory T cells, and Natural Killer (NK) cells, expressing at least one of an antigen-recognizing receptor and a co-stimulatory ligand and methods of use therefore for the treatment of neoplasia and other pathologies where an increase in an antigen-specific immune response is desired.
摘要:
Safe, rapid and efficient methods for producing virus-specific or other antigen-specific T-cells from cord blood and other samples containing naive immune cells.
