Your blood-brain barrier (BBB) is a filtering layer of cells surrounding blood vessels in most areas of your brain. It’s a critical line of defense, keeping most harmful things out and most helpful things in.

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]

The blood-brain barrier (BBB) is a semipermeable and extremely selective system in the central nervous system of most vertebrates, that separates blood from the brain's extracellular fluid. It plays a vital role in regulating the transport of ...

Jan 21, 2025 · The blood–brain barrier provides critically important defense to the brain, protecting it from viruses, bacteria, and toxins. Read on to learn more about the blood–brain barrier

May 25, 2023 · Blood–brain barrier (BBB) is a natural protective membrane that prevents central nervous system (CNS) from toxins and pathogens in blood.

Aug 24, 2023 · Blood-Brain Barrier (BBB) is a selectively permeable membrane regulates the passage of a multitude of large and small molecules into the microenvironment of the neurons. It achieves this feat by with the aid of multiple cellular transport channels scattered along …

Mar 17, 2023 · The blood-brain barrier (BBB), first described by Paul Ehlrich (1885), is a highly selective semi-permeable membrane between the blood and brain interstitium. This unique barrier allows cerebral blood vessels to regulate the movement of …

Nov 18, 2020 · The different cells and structures contributing to developing this barrier are summarized along with the different functions that BBB plays at the brain–blood interface. We also explained the role of shear stress in maintaining BBB integrity.
