One of the CC chemokines secreted by MM cells is monocyte chemotactic protein-1 (MCP-1), which acts as a potent chemoattractant for monocytes, basophils, eosinophils, endothelial cells, a subset of T lymphocytes, and myeloma cells through its CCR2 receptor [9, 10]. The gene discussed is CCL2; the disease is Miyoshi myopathy.
