Boston University Researchers Develop Scalable Method for CAR-T Cancer Treatment
Researchers at the Center for Regenerative Medicine at Boston Medical Center and Boston University have developed a new, scalable method for generating CD4+ helper T cells from induced pluripotent stem cells (iPSCs). This breakthrough, published in Stem Cell Reports, addresses a significant challenge in the development of 'off-the-shelf' CAR-T therapies. Current CAR-T treatments involve collecting a patient's T cells, genetically modifying them to target cancer, and then reintroducing them, a process that is both expensive and time-consuming. The Boston team, led by Dr. Gustavo Mostoslavsky and doctoral student Julian Amirault, focused on manipulating the Notch molecular signaling pathway. They found that by removing Notch signaling during later stages of T cell maturation and simultaneously reducing anti-T cell receptor signaling, they could enable developing cells to survive and mature into functional CD4+ T cells at scale. This protocol is described as simple, straightforward, and potentially scalable f...
