{Reference Type}: Journal Article {Title}: Making normal hematopoiesis invisible to CAR T cells. {Author}: Kim MY; {Journal}: Trends Cancer {Volume}: 9 {Issue}: 12 {Year}: 2023 12 18 {Factor}: 19.161 {DOI}: 10.1016/j.trecan.2023.10.001 {Abstract}: Two recent studies, by Casirati et al. and Wellhausen et al., report genetically engineering normal hematopoietic stem and progenitor cells (HSPCs) to be resistant to chimeric antigen receptor (CAR)-T cells, by changing a single amino acid in the target protein that abrogates CAR binding, without compromising protein function. This allows for selective targeting of cancer cells without harming normal hematopoietic cells.
