Additionally, other researchers found altered protein expression patterns of the inflammatory markers monocyte chemoattractant protein 2 (CCL8/MCP2), leukemia-inhibiting factor (LIF), and epithelial-derived neutrophil-activating protein (CXCL5/ENA-78) in the peritoneal fluid of patients that developed ALs [207]. The gene discussed is CCL8; the disease is amyotrophic lateral sclerosis.
