[The role of vascular endothelial growth factor in inflammatory processes].
The vascular endothelial growth factor (VEGF) is produced by different types of cells and has a major role in both, physiological and pathological angiogenesis. On the one hand VEGF is a strong mitotic and chemotactic factor for the endothelial cells, stimulating thus formation of new vessels, while on the other, it enhances the vascular endothelium permeability of the existing blood vessels which contributes to development and persistence of the inflammatory conditions. In the latter its activity is by 50 000 times higher than that of histamine. VEGF facilitates formation of oedema and leukocyte migration from the circulation to the site of inflammation. VEGF is also important in remodeling of the extracellular matrix. Moreover, it has an important significance in regulation of the immunological response, therefore plays a role in autoaggressive phenomena as well as immediate- and delayed-type hypersensitivity. Its role in the pathogenesis of immunological and inflammatory diseases, including allergy, asthma and different skin disorders has been indicated.
