The blood–brain barrier (BBB) is a highly selective semipermeable border of endothelial cells that regulates the transfer of solutes and chemicals between the circulatory system and the central nervous system, thus protecting the brain from harmful or unwanted substances in the blood. [1]
Drug delivery to the brain is the process of passing therapeutically active molecules across the blood–brain barrier into the brain.This is a complex process that must take into account the complex anatomy of the brain as well as the restrictions imposed by the special junctions of the blood–brain barrier.
The cells of the neurovascular unit also make up the blood–brain barrier (BBB), which plays an important role in maintaining the microenvironment of the brain. [11] In addition to regulating the exit and entrance of blood, the blood–brain barrier also filters toxins that may cause inflammation, injury, and disease. [12]
Now, a study led by researchers at the Mayo Clinic in Florida has found unique molecular changes in the blood-brain barrier of people with Alzheimer’s disease, markers of which can be detected ...
The brain has a powerful ability to keep out blood containing unidentified elements, thanks to a feature known as the blood-brain barrier. Bioengineers believe that they can finally work around ...
The particles were also able to cross the blood-brain barrier. Earlier this year, a study was the first to link the presence of microplastics to higher rates of mortality in people who had higher ...
Edwin Goldmann (12 November 1862 – 12 August 1913) was a biomedical researcher and surgeon most famous for his contributions in first characterizing the blood–brain barrier. [ 1 ] Discovery of the blood–brain barrier
Within the brain, the glial limiting membrane is an important constituent of the blood–brain barrier. Experiments using electron-dense markers have discovered that functional components of the blood–brain barrier are the endothelial cells that compose the vessel itself.
