Blood-brain barrier regulation

چکیده
The existence of a barrier between the central nervous system (CNS) and the systemic circulation has been described over one hundred years ago. Since the discovery that this barrier was instigated by the barrier properties of the brain endothelial cells, research has focused on the identification of pathways how the brain endothelial cells are instructed to form the highly specialized blood-brain barrier (BBB). Even though our current understanding of BBB development is far from complete, recent literature shows a rise in knowledge of CNS-specific cues that can drive BBB development. In this commentary, we will provide a brief overview of brain selective factors that are critical in the development of barrier properties in the brain endothelium; in particular the role of retinoic acid will be discussed.

P27: KCNK2 and Adhesion Molecules in an in-Vitro Blood Brain Barrier Model
Two-pore domain potassium channels, like KCNK2, are known to play an important role in inflammatory diseases such as multiple sclerosis (MS). Upregulation of cellular adhesion molecules in mouse brain microvascular endothelial cells (MBMECs) of Kcnk2-/- mice resulted in elevated leukocyte trafficking into the central nervous system under inflammatory conditions. The current project aims to gain...

متن کاملEstrogen provides neuroprotection against brain edema and blood brain barrier disruption through both estrogen receptors α and β following traumatic brain injury
Objective(s):Estrogen (E2) has neuroprotective effects on blood-brain-barrier (BBB) after traumatic brain injury (TBI). In order to investigate the roles of estrogen receptors (ERs) in these effects, ER-α antagonist (MPP) and, ER-β antagonist (PHTPP), or non-selective estrogen receptors antagonist (ICI 182780) were administered. Materials and Methods: Ovariectomized rats were divided into 10 gr...

Introduction: Recent studies suggest that dietary virgin olive oil (VOO) reduces hypoxia-re oxygenation injury in rat brain. We have attempted to determine the effect of dietary virgin olive oil on brain lipidomics and its relationship with brain edema in a rat stroke model. Methods: Five groups, each consisting of 6 male Wistar rats, were studied. The first and second groups (control and s...
متن کاملEffect of Nesfatin-1 on Permeability of Blood Brain Barrier, Neurological Score and Brain Edema after Traumatic Brain Injury in Male Rats: A Behavioral and Biochemical Study
Background and purpose: Traumatic brain injury (TBI) is one of the most complex diseases of the central nervous system (CNS). Nesfatin is an 82-amino acid effective polypeptide in CNS. In this study, we investigated the role of nesfatin in neuron protection in the process of diffuse concussion in rats and also its effect on the level of matrix metalloproteinase-9. Materials and methods: In thi...
