Systemic lupus erythematosus (SLE) is associated with altered B cell responses but the underlying aetiology is still unclear. Here the authors show that a CD11chiT-bet+ B cell subset with a unique phenotype and transcriptome is increased in patients with SLE, can be expanded by IL-21, and may contribute to autoimmune responses in SLE.
