Good in vitro blood-brain barrier (BBB) models that mimic the in vivo BBB phenotype are essential for studies on BBB functionality and for initial screening in drug discovery programmes, as many potential therapeutic drug candidates have poor BBB permeation. Difficulties associated with the availability of human brain tissue, coupled with the time and cost associated with using animals for this...
Let $E$ be an elliptic curve over $Bbb{Q}$ with the given Weierstrass equation $ y^2=x^3+ax+b$. If $D$ is a squarefree integer, then let $E^{(D)}$ denote the $D$-quadratic twist of $E$ that is given by $E^{(D)}: y^2=x^3+aD^2x+bD^3$. Let $E^{(D)}(Bbb{Q})$ be the group of $Bbb{Q}$-rational points of $E^{(D)}$. It is conjectured by J. Silverman that there are infinitely many primes $p$ for which $...
The brain vasculature has several specific features, one of them being the blood-brain barrier (BBB), which supports and protects by allowing for passage oxygen nutrients, while at same time preventing pathogens toxins. BBB also prevents efficient delivery drugs to brain, e.g. treatment tumors. In murine perivascular fibroblasts were recently identified as a novel potential constituent BBB. Her...
The blood-brain barrier (BBB) presents a major obstacle to the treatment of malignant brain tumors and other central nervous system (CNS) diseases. For this reason, a meeting partially funded by an NIH R13 grant was convened to discuss recent advances and future directions in translational research in neuro-oncology and the BBB. Cell biology and transport across the BBB, delivery of agents to t...
The delivery of hydrophilic drugs to the brain is limited by the various barriers in the brain. In this respect, the blood-brain barrier (BBB) is the most important barrier because it functions as a physical and metabolic barrier represented by the endothelial cells of brain capillaries. In order to treat brain diseases, drugs must pass the BBB by targeting them to internalizing transport syste...
The blood-brain barrier (BBB) presents a significant obstacle to delivery of targeted therapies to brain tumors. In this issue of the JCI, Staquicini and colleagues apply an in vivo phage-displayed library of random peptides to identify differentially expressed peptides that can be used to transport targeted agents across the intact BBB. The authors uncover a non-canonical, peptide-mediated iro...
Blood–Brain Barrier Therapy The blood–brain barrier (BBB) is a bottleneck in the treatment of brain tumors. In article number 2203678, Liang Wang, Yinyan Lin Feng, and co-workers summarize current approaches to overcome BBB, such as use “Trojan horse” molecular modifications for deception, describe variety micro-nanocarriers targeted tumor therapy.
A number of studies report that a diet high in protein influences cognitive performance, but the results are inconsistent. Studies demonstrated that protein from different food sources has differential effects on cognition. It is increasingly recognized that the integrity of cerebrovascular blood-brain barrier (BBB) is pivotal for central nervous system function. However, to date, no studies ha...
Cerebral microvascular endothelial cells form the anatomical basis of the blood-brain barrier (BBB), and the tight junctions of the BBB are critical for maintaining brain homeostasis and low permeability. Ischemia/reperfusion is known to damage the tight junctions of BBB and lead to permeability changes. Here we investigated the protective role of 3-(5'-hydroxymethyl-2'-furyl)-1-benzylindazole ...
BACKGROUND The blood-brain barrier (BBB) formed by brain endothelial cells interconnected by tight junctions is essential for the homeostasis of the central nervous system. Although studies have shown the importance of various signaling molecules in BBB formation during development, little is known about the molecular basis regulating the integrity of the adult BBB. METHODS AND RESULTS Using ...
