Open Access Abstract Introduction The tumour necrosis factor TNF family ligands BAFF B-cell activating factor of TNF family and APRIL a proliferation-inducing ligand are essential for B-cell survival and function. Elevated serum levels of BAFF and APRIL have been reported earlier in patients with systemic lupus erythematosus SLE . Since autoantibody formation in the central nervous system CNS is a distinct feature of neuropsychiatric SLE NPSLE we have investigated whether NPSLE is associated with an enhanced intrathecal production of APRIL and BAFF. Methods Levels of BAFF and APRIL in cerebrospinal fluid CSF and serum from healthy controls SLE patients without CNS involvement and patients with NPSLE were determined by enzyme-linked immunosorbent assay.
