Chinese Study Links High Autoantibody Levels Against PD-1 to Lupus Disease Activity
Patients with new-onset lupus erythematosus (SLE) have high levels of autoantibodies against programmed cell death protein 1 (PD-1), an immune response co-inhibitor, new research from China shows. The study, “Elevated serum autoantibodies against co-inhibitory PD-1 facilitate T cell proliferation and correlate with disease activity in new-onset systemic…
