“…An increased VEGF expression was previously shown in vitro in the mesentery of portal hypertensive mice (4). Studies by Fernandez et al (33,34) showed a decrease of the intestinal neovascularization, splanchnic blood flow and formation of portosystemic collaterals in portal hypertensive rats by the administration of anti-VEGF receptor-2 monoclonal antibodies. Moreover, Chun et al (35) reported that transforming growth factor beta1 (TGFbeta1) can activate macrophages to express angiogenic mediators such as VEGF.…”

“…Previous studies have demonstrated PHT and a high degree of portosystemic collaterals 2 weeks after PPVL and 6 weeks after CBDL. 14,15 For the WSS analysis, vascular corrosion casts were obtained in four PPVL, four CBDL and three SO rats, and experiments were performed on the same time points as described above.…”

“…Se ha observado que la administración cró-nica de inhibidores de los receptores de la VEGF a ratas con hipertensión portal previene la formación de colaterales portosistémicas (44). Diversos mecanismos, implicados a su vez en la patogénesis de la hipertensión portal, como la hipoxia tisular, factores de crecimiento, como el factor de crecimiento de fibroblastos (FGF), algunas citoquinas proinflamatorias, como las interleuquinas 1 y 6, y el estrés de rozamiento, van a inducir la expresión del gen VEGF y promueven la angiogénesis en diversas células (45).…”

“…Consecuencias similares se logran inhibiendo el TNF-alfa circulante, citoquina proinflamatoria cuya concentración sérica está aumentada en la hipertensión portal, y que estimula la actividad de la eONS (29). Más recientemente, se ha demostrado que el bloqueo de mediadores específicos de la angiogé-nesis, como el VEGF, también atenúa la colateralización portosistémica (44,51). Fernández y cols.…”
