pCDCAR1 CD19×CD22 h(BBζ)(CAR-LC355)

The vector of anti-CD19×CD22 dual chimeric antigen receptor (CAR) is constructed for the engineering of T cells to target human CD19 and CD22. The T cells are genetically modified through transduction with a lentiviral vector expressing bivalent scFv of anti-CD19×CD22 antibody and linked to 4-1BB (CD137) and CD3ζ signaling domains. And the vector product was designed for the treatment of CD19+/CD22+ cancer.

Discription of Signaling Cassetes
41BB
CD137 (also known as 4-1BB) is a surface co-stimulatory glycoprotein originally described as present on activated T lymphocytes, which belongs to the tumor necrosis factor (TNF) receptor superfamily. It is expressed mainly on activated CD4+ and CD8+ T cells, and binds to a high-affinity ligand (4-1BBL) expressed on several antigen-presenting cells such as macrophages and activated B cells. On the basis of preclinical observation, this molecule can promote the persistence of antigen-specific and antigen-nonspecific chimeric antigen receptor T-cells to significantly increases antitumor activity.
CD3ζ
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.
