Background & Aims: Blood-brain barrier (BBB) breakdown and nitric oxide (NO) overproduction following cerebral ischemia-reperfusion extensively happens in the subcortical regions (core areas). Hence, we assessed the effects of NO inhibition by L-NAME on transcription of the transmembrane proteins claudin-3 and 12, with key role in BBB structure, at subcortical areas following cerebral ischemia-...
Transendothelial trafficking of immune cells into the central nervous system (CNS) and disruption of the blood brain barrier (BBB) are pathophysiological hallmarks of neuroinflammatory disorders like multiple sclerosis (MS). Accumulating evidence suggest that oxidative stress plays a major role in the pathogenesis of MS, whereas a specific influence of oxidative stress on BBB dysfunction in MS ...
پیش زمینه و هدف: امروزه پیوند سلول های بنیادی از روش های متداول برای درمان ضایعات نخاعی (sci) به شمار می رود. مطالعات نشان داده اند که پیوند سلول های بنیادی عصبی (nscs) برای درمان sci علیرغم ایجاد بهبود حرکتی موجب ایجاد دردهای نوروپاتیک می شود. از آنجا که سلول های بنیادی مغز استخوان (bmscs) کاربرد فراوانی در درمان sci دارند لذا هدف از مطالعه حاضر بررسی تأثیر پیوند سلول های مذکور در ایجاد دردها...
Human immunodeficiency virus type 1 (HIV-1), introduced into the brain by HIV-1-infected monocytes which migrate across the blood-brain barrier (BBB), infects resident macrophages and microglia and initiates a process that causes HIV-1-associated neurocognitive disorders. The mechanism by which HIV-1 infection circumvents the BBB-restricted passage of systemic leukocytes into the brain and disr...
Background. Blood-brain barrier (BBB) dysfunction may have a significant role in the pathogenesis of Alzheimer's disease (AD). Modifiable factors associated with BBB function may have therapeutic implication. This study tested the hypothesis that dyslipidemia is associated with BBB impairment in mild-to-moderate AD. Methods. Thirty-six subjects with AD were followed for 1 year. Fasting CSF and ...
section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
Blood-brain barrier (BBB) pathology leads to neurovascular disorders and is an important target for therapies. However, the study of BBB pathology is difficult in the absence of models that are simple and relevant. In vivo animal models are highly relevant, however they are hampered by complex, multi-cellular interactions that are difficult to decouple. In vitro models of BBB are simpler, howev...
