pCDCAR1 TP53 h(BBζ)(CAR-YJ321)

The vector of anti-TP53 chimeric antigen receptor (CAR) is constructed for the engineering of T cells to target human TP53. The T cells are genetically modified through transduction with a lentiviral vector expressing scFv of anti-TP53 antibody linked to 4-1BB (CD137) and CD3ζ signaling domains. And the vector product was designed for the treatment of Ovarian 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.

Introduction
TP53 is a tumor suppressor protein containing transcriptional activation, DNA binding, and oligomerization domains. TP53 responds to diverse cellular stresses to regulate expression of target genes, thereby inducing cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. Mutations in TP53 are associated with a variety of human cancers, including hereditary cancers such as Li-Fraumeni syndrome.
