Revolutionary Therapies: CAR T-Cell and Stem Cell Treatments Show Promise in Autoimmune Diseases

CD19-targeting CAR T-cell therapy shows promise in treating refractory antisynthetase syndrome, as demonstrated in a case study. A 41-year-old male patient with progressive myositis and interstitial lung disease received CD19-targeting CAR T cells after failing to respond to available therapies. After 8 months, there were no signs of myositis on MRI, and the patient's overall condition improved. B-cell counts initially decreased but eventually recovered. This study suggests that CAR T-cell therapy could be a safe and effective treatment option for refractory antisynthetase syndrome.
