Introduction: Wound healing is a complex, inflammation and extracellular matrix (ECM) remodeling associated process in which dermal fibroblasts play a central role. Based on literature data, high-NaCl intake induces inflammatory response and causes or often worsens several pathological conditions. However, the effect of high-NaCl diet on the process of skin ECM remodeling and fibroblast activity is not fully understood.
Methods: To investigate the effect of high-NaCl consumption on skin tissue remodeling we kept the mice on high NaCl diet and than we performed the imiquimod (IMQ) induced mouse model of dermatitis. Dermal mRNA level of ECM component collagen-1, fibronectin and the fibroblast marker alpha smooth muscle actin (α-SMA) was measured by real-time RT-PCR. The effect of increased NaCl concentration on ECM production and cellular motility was investigated on human primary dermal fibroblasts in vitro.
Results: The effect of high-NaCl diet on the IMQ treated group resulted in lower skin mRNA levels of fibronectin, collagen1 and α-SMA compared to the IMQ treated mice on normal salt diet. Increased NaCl concentration reduced the fibronectin and collagen-1 mRNA expression, as well as the TGF-β induced fibroblast motility in human dermal fibroblast cell line.
Conclusion: Taken together, our results reveal that high salt intake reduces the expression of ECM markers and motility of dermal fibroblasts. Therefore high dietary NaCl intake may be responsible for hindered wound healing.
