CAR-T cells compose of an antigen-binding single-chain variable fragment (scFv) domain, a signal transduction domain and a transmembrane domain, which allow the CAR-T cells to recognize tumor cells in MHC-unrestricted manner [42], [43]. In addition to the advantages of CAR-T cells, CAR-...
在一个双特异性单链抗体(bi-scFv)的研究中,该抗体靶向hEGFRvIII以及T细胞上的人源 CD3ε(不与其他种属的CD3反应),为了更加准确的预测其在人体内的药代动力学情况,在临床前PK研究中使用了人CD3转基因小鼠作为动物模型,药代动力学研究发现血浆和全血中的hEGFRvIII:CD3 bi-scFv的初始半衰期为~8分钟,终末半衰期为~...
Single-chain Fv (scFv) 25 ≈1 day a Adapted from Iznaga-Escobar N et al. Methods Find Exp Clin Pharmacol 2004;26:123–7. There are disadvantages to the prolonged half-life exhibited by intact mABs. For example, those with the longest half-lives and lowest clearance rates diffuse poorly ...

In vitro and in mice, CAR-T cells with the scFv exhibit potent cytotoxicity against NPM1c+HLA-A2+ leukaemia cells and primary AML blasts, but not NPM1c–HLA-A2+ leukaemia cells or HLA-A2– tumour cells. Therapies using NPM1c CAR-T cells for the treatment of NPM1c+HLA-A2+ AML may...

ABD swapping with anti-CD276 scFv (CD276.MG) or with FGFR4-targeting F8-FR4 sdAbs; a Hinge Domain (HD) and a Transmembrane domain (TM) derived from either CD8α or CD28; one or two Co-Stimulatory Domains (CSDs), derived from CD28 or 4-1BB; and a CD3ζ Signaling Domain (SD). ...
Using this format, we generated a bispecific antibody, REGN1979, targeting the B cell marker, CD20 and the CD3 component of the T cell receptor, which triggers redirected killing of B cells. In mice, this antibody prevented growth of B cell tumors and also caused regression of large ...
(B) Schematic representation of the chimeric antigen receptors (CARs) containing the IgHL signal peptide, scFv sequences (SM5-1 targeting HCMV/gB and 6G4 or 7A1 targeting EBV/gp350), the IgG4 hinge, the IgG1 Fc CH3 spacer, the CD28 transmembrane and endocytoplasmic domains, and CD3 ...
Finally, T cell concentration was adjusted to 1 x 106 cells/mL and T cells were cultured without CD3/CD28 beads (Fåne et al., 2022). An important factor that might influence the interpretation of the data is donor variations, thus, to strengthen the reproducibility of the results we ...
