The vascular endothelial growth factor +405 G/C polymorphism in psoriasis

      Psoriasis is a chronic inflammatory disorder of the skin keratinocytes, involving the expansion and dilation of superficial dermal microvasculature. Both genetic and environmental factors have important roles in the development of the disease. Angiogenesis has been indicated as a common and important pathogenic component in psoriasis, and VEGF, being a key contributor to angiogenesis, was further considered. Several studies have demonstrated that VEGF expression levels were increased in the sera of psoriasis patients [
