IL6 and Parkinson disease: Based on the results of GO-BP enrichment analysis, these target genes mainly focused on the cellular response to lipopolysaccharide, cytokine-mediated signaling pathway, positive regulation of leukocyte cell-cell adhesion, humoral immune response, neuroinflammatory response, etc. In addition, we also identified five hub genes (RELA, IL-6, TP53, MAPK3, and MAPK1) as the most promising candidate targets of PD acting on the progression of chemotherapy-induced neuropathic pain.
