It is known that preeclampsia alters the neurodevelopment of the descent of preeclamptic mothers. Given that cerebellar development occurs mainly when the brain in gestation is impacted by the preeclampsia, and it is described that in preeclampsia exist a placental dysregulation of pro- and anti-angiogenic factors, such as vascular endothelial growth factor and its main receptors: VEGF receptor 2 phosphorylated at Y951 and VEGF receptor 2 phosphorylated at Y1172, we decided to evaluate, the effect of experimental preeclampsia on the cerebellar expression of VEGF and two of its receptors, pY951 VEGF R2 and pY1172 VEGF R2. This evaluation was carried out in the progeny of preeclamptic mothers in an ontogenetic stage equivalent to infancy, using the experimental model of preeclampsia based on the administration of N (ω)-nitro-L-arginine methyl ester in pregnant Sprague–Dawley rats. As part of our assessment of the functional correlate of the cerebellum, we evaluated the balance and locomotor learning in the progeny using the rotarod test. We observed that experimental preeclampsia increased the blood pressure in the mothers, along with proteinuria and the alteration of the level of vascular endothelial growth factor in the cerebellar vermis of both sexes progeny. Furthermore, it was observed an increase VEGF receptor 2 phosphorylated at Y951 in the male progeny. Additionally, it was observed a decrease in locomotor learning among daughters of preeclamptic mothers. Future studies are necessary to continue understanding the complex pathophysiology of preeclampsia and how it affects the neurodevelopment of the offspring.
