Abstract

Objective: To document the expression patterns of various matrixins, cytokines, and angiogenic factors in plasma to assess their involvement in the pathogenesis of MMD.

Methods: This study included plasma samples from 20 MMD patients and nine healthy individuals. The plasma concentration of five matrix metalloproteinases (MMP-1, MMP-2, MMP-3, MMP-9, MMP-12), monocyte chemoattractant protein-1 (MCP-1), resistin, three interleukins (IL-1β, IL-6, IL-8), tumor necrosis factor-α (TNF-α), vascular endothelial growth factor (VEGF), platelet-derived growth factor BB (PDGF-BB), and basic fibroblast growth factor (bFGF) was determined using multianalyte profiling systems. The concentration of the tissue inhibitors of metalloproteinase (TIMP-1 and TIMP-2) was measured using enzyme-linked immunosorbent assay. Gelatin zymography for MMP-2 and MMP-9 was also performed.

Results: MMD patients exhibited significantly higher plasma concentrations of MMP-9, MCP-1, IL-1β, VEGF, and PDGF-BB, and lower plasma concentrations of MMP-3, TIMP-1, and TIMP-2 compared with healthy controls. Significant correlations were found among MMP-9, MCP-1, VEGF, PDGF-BB, and TIMP-2 in MMD patients.

Conclusion: There were distinctive expression patterns of matrixins, cytokines, and angiogenic factors in MMD patients, which seemed to correlate with disease pathogenesis. The balance between MMPs and TIMPs was disrupted in MMD and correlated with disease pathogenesis. Increased plasma levels of MCP-1 and VEGF in MMD patients may play a role in the recruitment of vascular progenitor cells and in the formation of collateral vessels.
