Together with base editors, prime editors, and alternative nuclease platforms, CRISPR-Cas9 technology has transformed the field of genetic engineering by providing unprecedented precision in genome editing and creating new opportunities for therapeutic interventions. This technology comprises a versatile genome-editing toolkit for achieving a variety of therapeutic objectives. In the context of leukemia, a group of life-threatening hematologic malignancies, CRISPR-Cas9 has emerged as a transformative tool for immunotherapy.

By enabling targeted modifications of immune cells, such as T cells, this technology enhances their ability to recognize and eradicate leukemic cells. CRISPR-Cas9 facilitates the disruption of immune checkpoint inhibitors, the insertion of chimeric antigen receptors (CARs), and the correction of genetic mutations that drive leukemia progression. These advancements have led to the development of more potent and personalized immunotherapies, such as CAR-T cell therapies, with improved efficacy and reduced off-target effects.

Moreover, CRISPR-Cas9 allows researchers to model leukemia in vitro, providing deeper insights into disease mechanisms and accelerating the discovery of novel therapeutic targets. Despite challenges such as delivery efficiency and potential immunogenicity, the integration of CRISPR-Cas9 into leukemia immunotherapy represents a paradigm shift, offering hope for durable remissions and potentially curative outcomes.

As clinical trials progress, this technology promises to redefine the standard of care for leukemia patients, ushering in a new era of precision medicine. This narrative review explores the revolutionary applications of CRISPR-Cas9 in redefining therapeutic strategies for leukemia.
