pCDCAR1 FRα h(CD137ζ)(CAR-MZ155)
The vector of anti-FRα (Folate receptor-alpha) chimeric antigen receptor (CAR) is constructed for the engineering of T cells to target human FRα (Folate receptor-alpha) . The T cells are genetically modified through transduction with a lentiviral vector expressing scFv of anti-FRα (Folate receptor-alpha) antibody linked to CD137 and CD3ζ signaling domains. And the vector product was designed for the treatment of FRα positive human cancers.

Discription of Signaling Cassetes
CD137 is a member of the tumor necrosis factor (TNF) receptor family. Its alternative names are tumor necrosis factor receptor superfamily member 9 (TNFRSF9), 4-1BB and induced by lymphocyte activation (ILA). It is currently of interest to immunologists as a co-stimulatory immune checkpoint molecule. CD137 can be expressed by activated T cells, but to a larger extent on CD8 than on CD4 T cells. In addition, CD137 expression is found on dendritic cells, B cells, follicular dendritic cells, natural killer cells, granulocytes and cells of blood vessel walls at sites of inflammation.
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.
