anti-CD19 CAR-T therapy

This study aimed to optimize the SP sequence by site-directed mutagenesis and investigate its impact on the killing function of CD19-CAR-T...In summary, this study revealed that increasing the N-terminal positive charge of the signal peptide can improve the expression efficiency of CAR and promote the killing of CD19+ target cells. These findings provide a scientific basis the optimization and clinical application of CAR structure.

The median doses of CD22 and CD19 CAR T cell infusions were 4.1 × 10/kg and 4.0 × 10/kg, respectively. Both the estimated 1-year progression-free and overall survival rates were 55.6%. Our preliminary results indicated that salvage therapy with CD19/CD22 CAR T cell infusion alone and that in combination with ASCT are effective in treating some adult patients with r/r Burkitt lymphoma.
