摘要
Abstract CXCL 14 serves as a chemoattractant for activated macrophages, immature dendritic cells and natural killer cells, as well as an antiangiogenic factor by preventing the migration of endothelial cells. CXCL 14 also exerts an inhibitory effect on the CXCL 12/ CXCR 4 signaling pathway, which is involved in the maintenance of T‐helper (Th)2 bias, and promotes Th1 immune response under the physiological and pathological conditions. Because CXCL 14‐mediated biological processes seem to be involved in the development of systemic sclerosis ( SS c), which is characterized by Th2/Th17‐skewed immune polarization and impaired neovascularization, we investigated the clinical correlation of serum CXCL 14 levels in patients with this disease. Serum CXCL 14 levels were significantly decreased in SS c patients compared with healthy individuals and in diffuse cutaneous SS c patients relative to limited cutaneous SS c patients. SS c patients with digital ulcers had serum CXCL 14 levels significantly lower than those without. Furthermore, i.v. cyclophosphamide pulse significantly increased serum CXCL 14 levels as compared with the baseline in SS c patients with interstitial lung disease successfully treated with this therapy. These results indicate that decreased CXCL 14 expression may contribute to the maintenance of Th2‐skewed immune polarization and dysregulated neovascularization, both of which underlie the developmental process of SS c.
