To address these issues, a novel allogeneic CAR-T therapy with broader target specificity was developed, optimizing its manufacturing process. Using CRISPR/Cas9, TCR and HLA class I complex expression were eliminated from donor T cells to reduce the risk of immune rejection and graft-versus-host disease. Additionally, NKG2D CAR, targeting eight ligands upregulated in both solid and hematological tumors, was lentivirally transduced. This study optimized CAR-T cell manufacture by testing various interleukin supplements (IL-2, IL-7/IL-15, IL-7/IL-15/IL-21). Results showed that IL-7/IL-15/IL-21 supplementation produced CAR-T cells with the most suitable characteristics in terms of genetic modification efficiency, cell proliferation, antitumor activity and memory profile. This new allogeneic NKG2D CAR-T therapy represents a promising universal treatment for a variety of cancers. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 Internacional A novel early memory-enriched allogeneic NKG2D CAR-T cell therapy based on CRISPR/Cas9 technology for solid tumors info:eu-repo/semantics/article
