Anti-ErbB3 TCR-ABR-α (XW-388) CAR Vector (XS-1122-YF1308)

Online Inquiry  Datasheet

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

The vector of anti-ErbB3 TCR-fused Antigen Binding Receptor (TCR-ABR) CAR is constructed for the engineering of T cells to target Mouse ErbB3. The T cells are genetically modified through transduction with a lentiviral vector expressing scFv (XW-388) of anti-ErbB3 antibody linked to TCRα subunit. The vector product was designed for the discovery and development of cellular therapy against Breast cancer. The TCR-ABR can effectively reprogram an intact TCR complex to recognize tumor surface antigens. TCR-ABR-T cells are shown to engage the signaling capacity of the entire TCR complex in an HLA-independent manner.

  • Discription of Signaling Cassetes
  • The scFv used to generate CAR-T cells or single domain antibodies can be fused to the extracellular N-termini of TCRα, TCRβ, CD3γ, CD3δ, or CD3ε subunits, resulting in the activation of target-specific TCR-ABR-T cells. TCR-ABR-T cells have been shown to use the entire TCR complex's signaling capacity in an HLA-independent manner.

  • Introduction
  • This gene encodes a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound protein has a neuregulin binding domain but not an active kinase domain. It therefore can bind this ligand but not convey the signal into the cell through protein phosphorylation. However, it does form heterodimers with other EGF receptor family members which do have kinase activity. Heterodimerization leads to the activation of pathways which lead to cell proliferation or differentiation. Amplification of this gene and/or overexpression of its protein have been reported in numerous cancers, including prostate, bladder, and breast tumors. Alternate transcriptional splice variants encoding different isoforms have been characterized. One isoform lacks the intermembrane region and is secreted outside the cell. This form acts to modulate the activity of the membrane-bound form. Additional splice variants have also been reported, but they have not been thoroughly characterized.
