Three patients in the UK are participating in a trial for a new CAR T-cell therapy aimed at treating lupus, an autoimmune disease with no cure. The therapy modifies the immune system to attack harmful cells, potentially reducing the need for lifelong medication. Experts express hope that this treatment could revolutionize lupus care, following promising results from a German trial. One patient, Katie Tinkler, shares her excitement about the treatment, hoping it will bring hope to others with autoimmune diseases.
