The immunosuppressive cellular elements of the TME in MM include regulatory T cells (Tregs), regulatory B cells (Bregs), and myeloid-derived suppressor cells (MDSC), whereas the humoral elements include several growth factors and cytokines such as IL-10 that activates Tregs and M2 macrophages and TGF-β which inhibits cytotoxic T-cells and NK cells [42,43,44,45,46,47,48,49]. The gene discussed is IL10; the disease is Miyoshi myopathy.
