A German woman’s three life-threatening autoimmune diseases were put into remission after a CAR-T cell therapy treatment. Her conditions, including autoimmune haemolytic anemia (AIHA), were caused by “wayward” B-cells, which produce antibodies, said The Guardian. With standard treatments no longer working, doctors extracted her white blood cells, isolated the T-cells and engineered them to recognize CD19, a protein found on B-cells. Once these T-cells were reinfused into the patient’s body, they began “destroying” the “rogue” B-cells, and within weeks her conditions improved.
