Study reported that low CD19/CD21 expression is a general early feature of B cells in systemic lupus erythematosus (SLE) and is associated with an impairment of TLR9 response in these cells. Plasmacytoid dendritic cells from SLE patients that express TLR9, but not CD19, display normal TLR9 function. Thus, decreased CD19/CD21 expression combined with defective TLR9 function may fail to prevent autoreactive B cell death. | Impaired TLR9 responses in B cells from patients with systemic lupus erythematosus.
