High blood pressure produces ventricular dilation, variations in circumventricular organs and changes in the cerebrospinal fluid compositions. On the other hand, chronic hypertension in spontaneously hypertensive rats can cause changes in the integrity of the brain barriers: blood-cerebrospinal fluid barrier and blood brain barrier. The permeability of the(More)
It has been reported that spontaneously hypertensive rats (SHR) show ventricular dilation, changes in CSF proteins and variations in the circumventricular organs (CVO) such as: the subcommissural organ (SCO), the subfornical organ (SFO) and the area postrema (AP) which are located in the walls of the third and fourth ventricles. On the other hand, p73(More)
Background Arterial hypertension produces ventricular dilation, CSF protein composition variations as well as alterations in the circumventricular organ and choroid plexus (CP). Cerebrospinal fluid (CSF) has an important relationship with the blood and the brain, and encephalic pathology could alter the connections between the blood, brain and CSF, and(More)
Background The choroid plexus is mainly involved in the production of cerebrospinal fluid (CSF) by using the free access to the blood compartment of the leaky vessels. In order to separate blood and CSF compartments, choroid plexus epithelial cells and tanycytes of circumventricular organs constitute the blood–CSF–brain barrier. The choroid plexus is(More)
The Syndrome of Inappropriate Antidiuretic Hormone (SIADH) is a disease characterized by hyponatremia and hyperosmolality of urine, and where vasopressin, angiotensin II and catecholamines are implicated in salt water balance, cardiovascular and blood pressure regulation. Therefore, the aim of this study is to analyze the hypothalamic distribution of(More)
