NCIt synonyms : Autologous Anti-CD123 Chimeric Antigen Receptor T Cells; CD123 CAR-T Cells; Autologous Anti-CD123 CAR T Cells;
NCIt definition : A preparation of autologous T-cells engineered to express a chimeric antigen receptor
(CAR) specific for the tumor-associated antigen (TAA) CD123 (interleukin-3 receptor
alpha chain or IL3RA), with potential immunostimulating and antineoplastic activities.
Upon administration, the autologous anti-CD123 CAR-T cells target and bind to CD123
expressed on the surface of tumor cells. This induces selective toxicity in CD123-expressing
tumor cells. CD123, the alpha subunit of the IL-3 receptor, regulates the proliferation,
survival and differentiation of hematopoietic cells. It is overexpressed on a variety
of cancers, including myeloid leukemia, and the increased expression of CD123 on leukemic
stem cells (LSCs) is associated with poor prognosis.;
