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 [

,

], and that VEGF serum levels were directly correlated with disease activity [
[1]
]. Keratin14-VEGF (VEGF driven by K14 gene promoter) transgenic mice developed inflammatory
skin lesion with many cellular and molecular features mimic psoriasis [
