Transport of an antifungal trypsin inhibitor isolated from corn across the blood-brain barrier.
نویسندگان
چکیده
We determined whether an antifungal 14-kDa protein trypsin inhibitor isolated from corn is able to cross the blood-brain barrier. We found that it completely crossed the blood-brain barrier by means of a saturable mechanism at a rate of 0.153 microl/g. min, with about 0.082% of the intravenously injected dose being taken up per gram of brain.

P 61: MicroRNA as a Therapeutic Tool to Prevent Blood Brain Barrier Dysfunction in Neuroinflammation
Endothelial cells present in brain are unique and differ from other peripheral tissues in a number of ways, which ensures specific brain endothelial barrier properties. Endothelial dysfunction is the earliest event in the initiation of vascular damage caused by inflammation. Various microRNAs (miRNA) have been discovered in different cellular components of the blood bran barrier (BBB). miRNAs a...
متن کاملSetting-up an In Vitro Model of Rat Blood-brain Barrier (BBB): A Focus on BBB Impermeability and Receptor-mediated Transport
The blood brain barrier (BBB) specifically regulates molecular and cellular flux between the blood and the nervous tissue. Our aim was to develop and characterize a highly reproducible rat syngeneic in vitro model of the BBB using co-cultures of primary rat brain endothelial cells (RBEC) and astrocytes to study receptors involved in transcytosis across the endothelial cell monolayer. Astrocytes...

Background and purpose: Allicin has a wide range of pharmacological functions, all of which can be demonstrated in anti-inflammatory, antioxidant, antifungal and anti-tumor activities. In this research, we investigated the neuroprotective role of allicin in the process of diffuse traumatic brain injury and its effect on interleukin levels and histological changes in rats. Materials and method...

Blood-brain barrier transport of the selective serotonin reuptake inhibitor and antidepressant, citalopram, was studied using monolayers of bovine brain microvessel endothelial cells (BMECs). This study provides for the first time, evidence of a transport mechanism for a selective serotonin reuptake inhibitor (SSRI). Carrier-mediated transport, efflux mechanisms, as well as inhibition of metabo...
