We designed a lentiviral vector expressing a chimeric antigen receptor with specificity for the B-cell antigen CD19, coupled with CD137 (a costimulatory receptor in T cells [4-1BB]) and CD3-zeta (a signal-transduction component of the T-cell antigen receptor) signaling domains. (nih.gov)
Apart from the tumor lysis syndrome, the only other grade 3/4 toxic effect related to chimeric antigen receptor T cells was lymphopenia. (nih.gov)
The therapy is similar to but distinct from CD19-targeted chimeric antigen receptor T-cell therapy, or CAR T-cell therapy, in which a patient's T cells are genetically modified to target a molecule called CD19 on the surface of the cancer cells. (stanford.edu)

Instead of targeting a molecule called CD19 on the surface of the cancer cells, the new therapy targets a molecule called CD22. (stanford.edu)

Researchers hope that targeting CD19 and CD22 simultaneously may result in a powerful therapy - one that cancer cells are unable to evade. (stanford.edu)
Researchers genetically modify the T cells to recognize specific molecules on the cancer cells' surfaces and kill the cells. (stanford.edu)
But patients whose cancer cells don't express CD19, or which tamp down their expression to evade the treatment, either don't respond or can relapse. (stanford.edu)
