pCDCAR1 GD2 h(28γ), NK (CAR-NK-2-M330-BG)


All products and services are For Research Use Only and CANNOT be used in the treatment or diagnosis of disease.

The vector of anti-GD2 chimeric antigen receptor(CAR) is constructed for the engineering of NK cells to target Human GD2. The NK cells are genetically modified through transduction with a lentiviral vector expressing scFv of anti-GD2 antibody linked to CD28 transmembrane domain/ endodomain and FcεRIγ signaling domains. And the vector product was designed for the treatment of neuroblastoma and melanoma.

  • CD28
    CD28 (Cluster of Differentiation 28) is one of the proteins expressed on T cells that provide co-stimulatorysignals required for T cell activation and survival. CD28 is the receptor for CD80 (B7.1) and CD86 (B7.2) proteins which are expressed on antigen-presenting cells(APC). CD28 modulates the primary TCR/CD3ζ signal in a different fashion than the late costimulatory elements OX40 and 4-1BB. CD28 enhances the expression of downstream regulators that impact on T-cell proliferation, death, differentiation, and effector functions. CAR+ T cells containing the CD28 endodomain showed strikingly enhanced sustained T cell activation, growth, survival. And CD28 results in a brightly expressed, stable receptor as the transmembrane domain. Including CD28 costimulatory domains in CARs led to enhanced anti-malignancy efficacy.
    FcεRIγ
    The high-affinity IgE receptor, also known as FcεRI, or Fc epsilon RI, is the high-affinity receptor for the Fc region of immunoglobulin E (IgE). FcεRI is a key molecule involved in allergic reactions. It is a tetramer composed of 1alpha, 1 beta, and 2 gamma chains. The gamma chains are also subunits of other Fc receptors. The scFv-based CARs engineered to contain a signaling domain from FcεRIγ have been shown to deliver a potent signal for T cell activation and function.

Target cell killing analysis of the GD2 CAR T cells, 14.18. The OS cells transduced with a lentiviral wasabi green fluorescence reporter gene were used as target cells,
and plated into 96 or 48 wells for 2 hours before adding the different CAR T cells (Jurkat or primary T cells, at E:T ratio 3:1).
