Distinct peripheral B-cell immunophenotypes define clinical heterogeneity in childhood-onset systemic lupus erythematosus
B-cell dysregulation is central to the pathogenesis of childhood-onset systemic lupus erythematosus (cSLE), yet the B-cell immunophenotypes across disease states remain incompletely defined. This study aimed to investigate the mechanistic basis and clinical relevance of B-cell–mediated immune dysregulation in cSLE. Per...
