Changes in one cytokine (interleukin [IL]-6), one cytokine-related protein (IL-1 receptor antagonist [IL-1RA]), and three chemokines (eotaxin, monocyte chemoattractant protein [MCP]-1, and I-TAC [CXCL11]) were observed immediately after infection in most CMs. The gene discussed is CXCL11; the disease is infection.
