Immunity boosting treatment enhances CAR-T cell therapy for blood cancers (IMAGE) WashU Medicine Caption A study by researchers at Washington University School of Medicine in St. Louis shows that treatment with an immunity boosting protein called interleukin 7 (IL-7) after an infusion of genetically modified T cells causes the cancer-fighting CAR-T cells to grow in number and become more effective at killing tumor cells. Shown are CAR-T cells infiltrating a lymphoma tumor in a mouse. Tumor cells are shown in blue, tumor-attacking CAR-T cells in green and immune cells called macrophages in red.
