CCL3 and acquired idiopathic inflammatory myopathy: In addition, weak to moderate positive correlations between Hsp90 and several crucial cytokines/chemokines involved in the pathogenesis of IIM were identified by the bivariate analysis, such as IL-1β, IL-6, IL-8, IL-17, interferon (IFN)-γ, C-X-C motif chemokine ligand 10 (CXCL10), monocyte chemoattractant protein 1 (MCP1, CCL2), macrophage inflammatory protein 1-alpha (MIP-1-α, CCL3), MIP-1-β (CCL4), vascular endothelial growth factor (VEGF), and platelet-derived growth factor (PDGF-BB) (p<0.05 for all correlations) (Table 5).
