2-Minute Neuroscience: Blood-Brain Barrier
In this video, I discuss the blood-brain barrier, a complex that surrounds most of the blood vessels in the brain and protects the brain from potentially dangerous substances that might be circulating in the blood stream. I discuss the tight junctions of endothelial cells as one of the main structural components of the blood-brain barrier, as well as describe the contribution of astrocytic end-feet to the formation and maintenance of the blood-brain barrier. Finally, I discuss the circumventricular organs as structures in the brain that lack a blood-brain barrier.

Crossing the Blood Brain Barrier: The Impact of the Reynolds Professorship
Because the blood brain barrier -- a system of blood vessels that protects the brain from toxins and chemical fluctuations -- does such an effective job, it also poses a problem in delivering medications that could help treat disorders like Parkinson's and Alzheimer's Diseases, according to Peter Searson, the inaugural Joseph R. and Lynn C. Reynolds Professor at Johns Hopkins University's Whiting School of Engineering. And named professorships -- along with being a great honor -- provide important opportunities to tackle such intricate problems in innovative ways, he continues. In this short video, hear Searson -- and graduate students, Amanda Levy and Andrew Wong -- explain what strides are being made with this research, and learn from Joe and Lynn Reynolds why their support has special m...

The Science of Cognition: Assessing Brain Health Through Organic Acid Metabolomics
In this advanced presentation, we will explore the intersection of metabolomics, hormone dynamics, and genetics in understanding cognitive health. Our focus will be on critical organic acids such as Homovanillic Acid (HVA), Vanillylmandelic Acid (VMA), kynurenate, and quinolate, which are key indicators of neurotransmitter activity and brain function.
We will discuss how these metabolites interact with crucial hormones like estrogen and cortisol, and how their modulation can influence cognitive functions and susceptibility to mental health conditions. This talk will also extend into the genetic predispositions that affect these metabolic pathways, providing a holistic view of individual biochemical variations and their impact on brain health.

TRANSCRIPT:
Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics in 2 minutes or less. In this installment I will discuss the blood-brain barrier.
The blood-brain barrier is a complex that surrounds most of the blood vessels in the brain. It acts as a barrier between the bloodstream and the extracellular space of the brain, allowing only certain substances like water, oxygen, and small lipid-soluble substances to easily cross from the blood into the brain. This prevents toxins, pathogens, and other potentially dangerous substances from crossing from the circulatory system into the brain.
It is thought that the central components of the structure of the blood-brain barrier are the tight junctions of endothelial cells, the cells that make up the interior surface of blood vessels. In other blood vessels throughout the body, there are small spaces between these endothelial cells; small blood-borne substances can pass through these spaces and into surrounding tissues.
The endothelial cells that make up the blood-brain barrier, however, are fused tightly together to form tight junctions that restrict diffusion across the blood vessel lining. Glial cells called astrocytes also have projections called astrocytic end-feet that extend to the walls of blood vessels that are part of the blood-brain barrier. Astrocytic end-feet often completely surround blood vessels in the brain and are thought to play critical roles in the formation of the blood-brain barrier. For example, they seem to be involved with signaling that prompts endothelial cells to form the tight junctions necessary to create the blood-brain barrier and they are believed to have multiple functions involving the maintenance and regulation of the blood-brain barrier.
The blood-brain barrier protects most of the blood vessels in the brain, but there are some areas that lack a blood-brain barrier, allowing substances to pass from the circulatory system to the brain and back. For example, the circumventricular organs are a group of structures lacking a blood-brain barrier that are centered around the ventricles of the brain. These structures are thought to be lacking a blood-brain barrier because their functions require access to the bloodstream. The posterior pituitary gland, for example, has to be able to release hormones directly into the bloodstream.

The blood-brain barrier refers to the highly selective permeability of blood vessels within the central nervous system. The barrier controls substances that can enter or leave the nervous tissue. It helps maintain the stable state, or homeostasis, of brain tissue, amid the fluctuations of circulating substances in the blood, many of which can act as neurotransmitters and could create chaos in neuronal activities if allowed to diffuse freely into the brain. The barrier also protects the brain from blood-borne pathogens and toxins.
The blood-brain barrier is composed of several cell types, including:
- Endothelial cells that form the wall of blood vessels;
- Mural cells, namely pericytes, partially covering the outside of endothelial cells;
- And glial cells astrocytes, whose extended processes, called end-feet, wrap around the vessels.
The endothelial cells alone can fulfill the functions of the blood-brain barrier, but their interactions with the adjacent cells seem to be required for its formation, maintenance and regulation.
The brain endothelial cells, unlike their counterparts in other tissues, possess unique properties that allow them to tightly control the passage of substances between the blood and brain. These properties can be classified into physical, transport, and metabolic categories:
- The brain endothelial cells are held together by tight junctions, which serve as physical barriers, preventing movements of substances through the space between cells.
- They have very low rates of vesicle-mediated transcellular transport.
- They control the movement of ions and substances with specific transporters, of which there are two major types: efflux transporters and nutrient transporters:
+ Efflux transporters use cellular energy to move substances against their concentration gradient. These transporters are usually located on the blood side of endothelial cells. They transport lipophilic molecules, which have passively diffused through the cell membrane, back to the blood.
+ Nutrient transporters, on the other hand, facilitate the movement of nutrients, such as glucose and essential amino acids, into the brain, down their concentration gradient.
- The brain endothelial cells also contains a number of enzymes that metabolize, and thus inactivate, certain neurotransmitters, drugs and toxins, preventing them from entering the brain.
An intact blood-brain barrier is critical for normal brain functions. Neurological diseases such as encephalitis, multiple sclerosis, brain traumas, Alzheimer's disease, epilepsy, strokes and tumors, can breach the barrier, and this, in turn, contributes to disease pathology and further progression.
But not all areas of the brain have the blood-brain barrier. Some brain structures are involved in hormonal control and require better access to systemic blood, so they can detect changes in circulating signals and respond accordingly. These non-barrier areas are located around the midline of the ventricular system, and are known as circumventricular organs. Some of their bordering regions have a leaky barrier.
The blood-brain barrier also has its downside. While it protects the brain from unwanted drugs and toxins, it also prevents therapeutic drugs from entering the central nervous system to treat diseases. Several strategies are developed to overcome this obstacle.

In this advanced presentation, we will explore the intersection of metabolomics, hormone dynamics, and genetics in understanding cognitive health. Our focus will be on critical organic acids such as Homovanillic Acid (HVA), Vanillylmandelic Acid (VMA), kynurenate, and quinolate, which are key indicators of neurotransmitter activity and brain function.
We will discuss how these metabolites interact with crucial hormones like estrogen and cortisol, and how their modulation can influence cognitive functions and susceptibility to mental health conditions. This talk will also extend into the genetic predispositions that affect these metabolic pathways, providing a holistic view of individual biochemical variations and their impact on brain health.
Further, we'll examine additional metabolites including xanthurenate, pyroglutamate, indican, and 8-Hydroxy-2'-deoxyguanosine (8OHdG). These compounds provide insights into nutrient balances, gut health, and oxidative stress levels, factors essential for maintaining optimal cognitive performance.
As we delve into how the DUTCH Test can be used to integrate metabolite and hormonal analysis with genetic data, attendees will gain cutting-edge knowledge on assessing and managing cognitive health through a comprehensive biochemical and genetic approach. This session is designed to empower clinicians with the latest tools and research to better understand and treat cognitive disorders in their practices.
