pCDCAR1 CLEC12A h(28ζ, α/β/γ)(CAR-LC335)

The vector of anti-CLL-1 chimeric antigen receptor (CAR) is based on the FcεRI receptor scaffold and constructed for the engineering of T cells to target human CLL-1. The T cells are genetically modified through transduction with a lentiviral vector expressing an alpha chain comprising a scFv of anti-CLL-1 antibody linked to FcεR1γ-SP and FcεR1γ-TM-IC, a beta chain comprising FcεR1γ-ΔITAM linked to CD28 signaling domain, a gamma chain comprising FcεR1γ-SP-ΔITAM linked to CD3ζ signaling domain. And the vector product was designed for the treatment of acute lymphoblastic leukemia.

Discription of Signaling Cassetes
CD28
CD28 (Cluster of Differentiation 28) is one of the proteins expressed on T cells that provide co-stimulatory signals 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.
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.
