Popis: Regulatory T-cells (T(Reg) cells) are increased in patients with multiple myeloma (MM). We investigated whether MM cells could generate and/or expand T(Reg) cells as a method of immuno-surveillance avoidance. In an in vitro model, CD4(+)CD25(-)FoxP3(-) T-cells co-cultured with malignant plasma cells (primary MM cells and cell lines) induced a significant generation of CD4(+)CD25(+)FoxP3(+) inducible T(Reg) cells (tT(Reg) cells; p
