| abstractText | Multiple myeloma (MM) is a plasma-cell disorder in which malignant plasma cells accumulate in the bone marrow and usually produce a monoclonal immunoglobulin. Usual presenting features of overt MM include recurrent osteolytic lesions, bacterial infections, anemia and renal insufficiency. MM is responsible for about 1 percent of all cancer-related deaths in Western countries. Its epidemiologic pattern remains obscure, and its cause unknown [1]. The presence of somatic mutations within the immunoglobulin genes of myeloma cells indicate that the putative myeloma-cell precursors have been stimulated by antigens within germinal centers and are either memory B cells or migrating plasmablasts. Myeloma cells proliferate slowly in the bone marrow and display a weak apoptotic index in vivo [2]. This suggest that some defects in the apoptotic process could be involved in this neoplasia. Interleukin-6 (IL-6) is known to be an essential survival factor of myeloma cells and to protect them from apoptosis induced by different stimuli (e.g. dexamethasone, CD95, serum starvation, gamma-irradiation). More recently, important works have been devoted to the biology of the soluble form of the IL-6R alpha i.e., sIL-6R alpha. These works give IL-6/sIL-6R alpha complex an important role in the biology of IL-6. The purpose of the current review is to emphasize the role of this complex in the pathogenesis of MM. |
