Available in PDF, EPUB and Kindle. Book excerpt: The vasculature of the central nervous system (eNS) is characterized by the existence of the blood-brain barrier (BBB), which can be regarded as both an anatomical and physiological phenomenon. The BBB is formed by a complex cellular system of endothelial cells, astroglia, pericytes, perivascular macrophages and a basal membrane, although the anatomic substrate of the BBB is the interendothelial tight junctions that form a continuous sealing. The BBB serves as an exquisitely controlled, functional gate to the eNS. It not only protects the brain from agents in the blood that could impair neurological function, but also controls the influx and efflux of numerous substances to maintain proper homeostasis and provide the brain with necessary nutrients. The structural and functional integrity of the BBB was shown to be dramatically altered during various diseases of the eNS, including neoplasia, ischemia, trauma, hypertension, inflammation and epilepsy. Recent years research has partially elucidated the mechanisms underlying the development of some of these brain disorders as well as the pathways used by different pathogens, like bacteria and viruses, to initiate eNS infections. The development of in vitro models of the BBB had instrumental role in the understanding of the involvement of the BBB in the pathogenesis of several eNS diseases. The intimate, functional association between the function of the brain and the activity of the BBB makes the later a target for pharmacological modulation that will expand the therapeutic possibilities for a range of neurological diseases.

Download or read book Drug Delivery to the Brain written by Elizabeth C.M. de Lange and published by Springer Nature. This book was released on 2022-05-24 with total page 810 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of new CNS drugs is notoriously difficult. Drugs must reach CNS target sites for action and these sites are protected by a number of barriers, the most important being the blood–brain barrier (BBB). Many factors are therefore critical to consider for CNS drug delivery, e.g. active/passive transport across the BBB, intra-brain distribution, and central/systemic pharmacokinetics, to name a few. Neurological disease and trauma conditions add further complexity because CNS barriers, drug distribution and pharmacokinetics are dynamic and often changed by disease/trauma. Knowledge of all these factors and their interplay in different conditions is of utmost importance for proper CNS drug development and disease treatment. In recent years much information has become available for a better understanding of the many factors important for CNS drug delivery and how they interact to affect drug action. This book describes small and large drug delivery to the brain with an emphasis on the physiology of the BBB and the principles and concepts for drug delivery across the BBB and distribution within the brain. It contains methods descriptions for studying drug delivery, routes and approaches of administering drugs into the brain, the influence of disease, drug industry perspectives, and a primer on neuroanatomy and physiological considerations written specifically for drug delivery scientists. Therewith, it contributes to an in-depth understanding of the interplay between brain (patho)-physiology and drug characteristics. Furthermore, the content is designed to be both cutting-edge and educational, so that the book can be used in high-level training of academic and industry scientists with full references to original publications.

Download or read book Blood brain Barrier Permeability and Transport Studied in Vitro written by Siti Rafidah Yusof and published by . This book was released on 2011 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: The blood-brain barrier (BBB) is the major site for regulation of molecular traffic between the blood and the central nervous system (CNS). In vitro models of brain endothelium are useful for studying BBB physiology. The present study applied two in vitro BBB models, immortalised rat brain endothelial cells (RBE4), and primary porcine brain endothelial cells (PBECs) to study uptake and permeation of small molecules and macromolecules at the BBB. -- The mechanism(s) involved in adenosine-mediated [3H] glutamate transport were examined. Initial uptake in RBE4 cells showed evidence for activation of Na+-dependent transport via excitatory amino acid transporters (EAATs) involving A2A and A2B receptors, and inhibition of Na+-independent transport via XG- involving A2B receptors. The findings are relevant to regulation of brain glutamate during CNS pathologies. However, no clear modulation was observed in the PBECs under similar conditions. -- The in vitro monocultured PBEC BBB model developed showed restrictive tight junctions (transendothelial electrical resistance, TEER, up to 1133±15 ocm2, n = 3 filter inserts), and functional expression of polarised uptake and efflux transporters. The dynamic range of Papp (propranolol: sucrose), indicator of resolution in drug screening, was improved from 2.3 to 57.6 (Papp propranolol 49 x 10-6cm/s; sucrose 0.85 x 10-6cm/s). Application of the model to assay antiepileptic drugs showed no detectable substrate recognition by P-glycoprotein. pCEL-X software (pION INC., Woburn USA) was applied for aqueous boundary layer correction and detailed permeability data analysis to derive intrinsic transcellular permeability Po ;in vitro-in vivo PQ correlation gave r2 = 0.62 for n = 20 compounds. Co-culture of the PBECs with astrocytes gave higher TEER, and functional transcytosis, evidence for upregulation of BBB phenotype. Properties of macromomolecular permeation suggested involvement of the glycocalyx as filtration site-barrier.
