“Vascular endothelial growth factor” (VEGF-) transgenic mice [29], “endothelial specific receptor tyrosine kinase” (K5-Tie2-) transgenic mice [30], and “transforming growth factor beta 1” (K5-TGFb1-) transgenic mice [31] are psoriasis animal models that highlight the importance of angiogenesis in this pathology. Here, TGFB1 is linked to psoriasis.
