Science and medicine progress by coming across new explanations to old questions and finding novel solutions and treatments to cure diseases. One such advance is CAR T-cell therapy to treat leukemia (Links to an external site.)Links to an external site.. It depends on the ability to genetically engineer chimeric T-cell receptors on a patient’s own T-cell population.
