Improving CAR T cell manufacturing in terms of costs and product quality is an important concern for expanding the accessibility of this therapy. One proposed strategy for improving T cell expansion is to use genetically engineered artificial antigen presenting cells (aAPC) expressing a membrane-bound anti-CD3 for T cell activation. The aim of this study was to characterize CAR T cells generated using this aAPC-mediated approach in terms of expansion efficiency, immunophenotype, and cytotoxicity.</p><p><strong>Materials and methods: </strong>In this experimental study, we generated an aAPC line by engineering K562 cells to express a membrane-bound anti-CD3 (mOKT3). T cell activation was performed by co-culturing PBMCs with either mitomycin C-treated aAPCs or surface-immobilized anti-CD3 and anti-CD28 antibodies. Untransduced and CD19-CARtransduced T cells were characterized in terms of expansion, activation markers, interferon gamma (IFN-γ) secretion, CD4/CD8 ratio, memory phenotype, and exhaustion markers. Cytotoxicity of CD19-CAR T cells generated by aAPCs and antibodies were also investigated using a bioluminescence-based co-culture assay.</p><p><strong>Results: </strong>Our findings showed that the engineered aAPC line has the potential to expand CAR T cells similar to that using the antibody-based method. Although activation with aAPCs leads to a higher ratio of CD8+ and effector memory T cells in the final product, we did not observe a significant difference in IFN-γ secretion, cytotoxic activity or exhaustion between CAR T cells generated with aAPC or antibodies.</p><p><strong>Conclusion: </strong>Our results show that despite the differences in the immunophenotypes of aAPC and antibody-based CAR T cells, both methods can be used to manufacture potent CAR T cells.
