BARRIOS, Emilia Elena et al. The endothelial growth factor vascular infection in murine liver by Schistosoma mansoni. Salus [online]. 2013, vol.17, n.3, pp.27-33. ISSN 1316-7138.

The antigens secreted by eggs of S. mansoni induce the proliferation of endothelial cells in vivo, as well as the production of Factor Vascular Endothelial Growth factor (VEGF), suggesting that the pathogenesis of schistosomiasis relations with angiogenic events. We evaluated the expression of VEGF, as a measure of angiogenesis stimulated by the eggs and worms S. mansoni in infection bisexual (BIS) and adult worms ( UNI infection ) in the liver of BALB / c mice before and after treatment with PZQ. These results indicate that abnormal production of VEGF with intense pro-inflammatory response not only associated with the activity of VEGF but also leukocyte infiltrates observed in the liver tissue caused by both secreted and eggs by adult forms S. mansoni are the mechanisms underlying granulomatous lesions observed during the course of schistosomiasis, and can be reversed at least the increased vascularization by using PZQ .
