5B9 is a 10-amino acid (aa) non-immunogenic peptide motif derived from La/SS-B which is an autoantigen known in Sjögren's syndrome and systemic lupus erythematosus. The scFv targeting the 5B9 motif has been employed to construct a UniCAR system that splits the antigen-binding domain and the signaling domain of the CAR into two separate parts. The two separate components of the anti-5B9 CAR were (a) a 5B9-binding CAR structure consisting of an anti-5B9 scFv linked by a hinge and transmembrane region to intracellular signal domains and (b) a switch molecule containing a tumor antigen-binding moiety fused to the 5B9 tag.

    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 antigennonspecific chimeric antigen receptor T-cells to significantly increases antitumor activity.
    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 4-1BB and OX40 can be used with CD3-zeta to transmit a proliferative/survival signal, or all three can be used together.
