IL-10, a cytokine involved in BAFF stimulation in monocytes and myeloid dendritic cells [47], did not influence BAFF expression in SGECs, and neither did TNF-α, which was recently reported to induce BAFF expression in fibroblast-like synoviocytes of patients with RA [45]. This evidence concerns the gene TNFSF13B and rheumatoid arthritis.
