The adherence of MM cells to bone-marrow stromal cells (BMSCs) induces NF-κB-dependent cytokine transcription and secretion (e.g. IL-6, TNFα and BAFF) by BMSCs, which in turn promote MM cell growth and survival through paracrine mechanisms [2], [11], [46]. Here, TNFSF13B is linked to Miyoshi myopathy.
