Autologous PD1-knockout CD19-specific CAR T Cells - CISMeF
Autologous PD1-knockout CD19-specific CAR T CellsNCIt concept
Preferred Label : Autologous PD1-knockout CD19-specific CAR T Cells;
NCIt synonyms : CD19-CAR T Cells with PD1 Knockout; Autologous Quikin-CD19-CART;
NCIt definition : A preparation of autologous CD4 and CD8 T-lymphocytes gene-edited to integrate a
chimeric antigen receptor (CAR) targeting the tumor-associated antigen (TAA) CD19
and to eliminate the programmed cell death 1 (PD-1; PDCD1; CD279; programmed death-1)
gene, with potential immunomodulating and antineoplastic activities. Upon administration,
autologous PD1-knockout CD19-specific CAR T cells specifically target and bind to
CD19-expressing tumor cells, thereby selectively lysing CD19-expressing tumor cells.
CD19 antigen is a B-cell specific cell surface antigen overexpressed in B-cell lineage
malignancies. Expression of PD-1, an inhibitory receptor expressed on activated T-cells,
plays a key role in CTL suppression, T-cell exhaustion and CTL apoptosis. PD-1 knockout
may abrogate T-cell exhaustion and increase T-cell activity and cytotoxicity.;
