pCDCAR1 ErbB2 h(8ζ), NK(CAR-NK-2-M331-8Z)
The vector of anti-ErbB2 (HER2) chimeric antigen receptor(CAR) is constructed for the engineering of NK cell to target human ErbB2. The NK cell is genetically modified through transduction with a lentiviral vector expressing scFv of anti-ErbB2 antibody linked to CD8 hinge-transmembrane domain and CD3-zeta signaling domains. And the vector product was designed for the treatment of breast carcinomas, ovarian carcinoma .
Targeting Cell Type
Breast carcinomas; ovarian carcinoma
Discription of Signaling Cassetes
CD8 CD8 (cluster of differentiation 8) is a transmembrane glycoprotein that serves as a co-receptor for the T cell receptor(TCR). Like the TCR, CD8 binds to a major histocompatibility complex (MHC) molecule, but is specific for the class I MHC protein. This affinity between CD8 and MHC molecule keeps the chimeric T cell receptor and the target cell bound closely together during antigen-specific activation.
CD3ζ, also known as T-cell receptor zeta, which together with T-cell receptor and CD3γ, δ , ε chain, forms the TCR-CD3 complex. ζ was expressed independently from the complex. The zeta chain plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. CD3-zeta,which contains 3 ITAMs, is the most commonly used endodomain component of CARs. It transmits an activation signal to the T cell after antigen is bound. CD3-zeta may not provide a fully competent activation signal and additional co-stimulatory signaling is needed. For example, chimeric CD28 and OX40 can be used with CD3-zeta to transmit a proliferative/survival signal, or all three can be used together.
