A patient with three different autoimmune diseases has entered complete remission after undergoing an experimental treatment that effectively reset her immune system.

The 47-year-old woman in Germany previously required daily blood transfusions to manage her conditions, two of which affected her blood cells.

She was given Chimeric Antigen Receptor (CAR-) T cell therapy, which involves extracting a sample of immune cells, ‘supercharging’ them against a specific target, and returning them to the body.
