Abstract

To address B-lineage acute lymphoblastic leukemia (B-ALL), we use a bioengineering approach to achieve high-efficient non-viral gene transfer of tumor-specific CAR+ T cells for on-demand use. Specifically, we have developed CD19-specific chimeric antigen receptors (CARs) to redirect the specificity of T cells for B-cell malignancies. We introduce CARs via a non-viral gene transfer: electroporation. We have fabricated and tested a series of high throughput micro-electroporation devices (HitMeDs) with the end result that a HitMeD can electroporate a large number (>109) human T cells within short time period (<4 hours). We connect the HitMeDs to a BTX pulse generator and a monitoring system. We have adapted HitMeDs to the electro-transfer of CAR mRNA which avoids the potential genotoxicity associated with vector integration. After electroporation, 70% to 80% of the T cells express CD19 -specific CAR.
