I study this and the vascular system in general. The problem is strokes create BIG STUFF like scabs in the brain that cannot get out. Enterecept injected ABOVE the BBB can recover some stroke people in 10 minutes.
I used to imagine a "filtering" layer that allowed "filtered" blood to pass. But it is more a multi-dimensions boundary sorrounding the vasculary system deep inside the brain. And it makes perfect sensne. I guess my previous visualization did not made sense, where would the filtered (rejected) material go and how (a brain liver LOL). Thanks for the explanation, I learned something today.
I had to pause to go look up what endothelial cells are lol. Is there a difference between these cells in the brain vs elsewhere? This also sparks my curiosity about how some germs can pass through that barrier.
The way I was taught this, I was told that the neurons are highly differentiated and hence the leucocytes can’t recognize them as a part of its own body so the immune system might attack the neurons if it comes directly in contact with them. This is why the blood brain barrier exists

3:45 don’t you mean water? Hydrogen is an element H which exists in nature usually as H2. It’s not hydrophilic, so I think you mean water. Water is H2O.
I personally don't belive in creation but when i see something like this it's really hard to comprehend how much "accidental" mutations are needed to achive a tiny but complex part of the incredibly complex body of a living creature.
Yeah I get these thoughts as well but u need to think in terms of probability and there is 100000000000000000000000000000000000000000000 planets in the observable universe (underestimated as well). Surely if u played dice one of those planets can eventually create complex life via natural selection by accidental mutation. Btw the natural selection ensures advantageous mutation keeps on staying, which causes the organism to become complex after many millions of years
the tight junction thing1 creates a back pressure of brain fluid in addition to keeping bigger solids out. You lost me a little w/Transporter Proteins. I wonder if it would pay off to study thickness's since you implied capillaries are linked together in creating this junction. i suppose on some level dimensia louis - body etc are starvation of the brain rather than impurities2 through the boundary; which is ironic since excess glucose probably loosens these junctions. 1 Rhonda Patrick interviewed by Peter Attia 2 Andrew Huberman in one of his core dumps probably with rhonda

Not all kids tho. I always liked spicy stuff more than sweet things. But the 'brain needs lots of glucose' thing could explain why it's usually effective to give a fainting or dizzy person sugar or ORS solution. It dissolves on the tongue & gets sent directly to the brain & jerks it awake. Might also explain why milk has lots of glucose.
Testosterone has a hard time getting across the blood brain barrier. If you are suffering from severe depression the hair follicle test seems to be the most accurate to determine how much testosterone the brain is getting. Urologist (not endocrinologist) who specialize in hormone therapy have accepted the anecdotal evidence for years but now their is a test.
i heard a source say serotonin doesn't cross BBB but it's precursors do... not that i buy into the whole ssri thing to begin with ... the neuro - pharma thing is so vague and snafu'ed. WE believe something like thorazine depletes L - dopa to levels that block serotonin creation ... just one of many NOT provable paradigms
@@georgeelgin3903 No easy answers here. They go down one promising path just to have it dead end. One drug that makes your mind release serotonin and dopamine is nicotine. This is why they believe it to be so addictive. Supposedly Tryptophan is a precursor to serotonin and can cross the blood brain barrier.

Hi Roger 😁😁
The connection to depression and microglial cells is fascinating as well, do you have a video on that?

Lmao at brain liver 😹
Great video........As a medical student, it was very nicely explained
All this protection, and yet when you smoke DMT the brain says “GIMMIE” and actively transports it across the barrier.
DMT is endogenous so, your brain already knows what it is and what to do with it. Now cocaine on the other hand....JK
@@501promo Yes indeed, and that is what is so wonderful and cool...
LSD, alcohol, uppers, downers ..all does that
Does the blood brain barrier ever get messed up from surgery, from the cells actually being physically cut into?
Love my morning daily dose of seeker
Very nicely explained.
I had to pause to go look up what endothelial cells are lol.

This also sparks my curiosity about how some germs can pass through that barrier.
This made me cry . Im so sorry
discuss how the structure of the BBB prevents the entry of some molecules but allows others through
Patrick kelly is a genius ,, keeps things really simple and organised.
I often hear that term, but never looking how it works. Thanks for the explanation!
Incredible engineering of brain. Mind blowing
Ultrasound is also used to temporarily widen the paths so to allow drugs to pass through the barrier
Ah yes, the thing Nicotine crosses.
And Alcohol.

Neurons: * overthink *
Immune System: NOOOOOOOO
Neurons: * shut the door so immune system can't stop them from overthinking *
a more interesting question is which chemicals pass through dopamine yes ? saratonin no ??
I always wondered this, but never decided to look it up.

But cancers can break blood brain barrier. On the other hand drugs used in chemotherapy find it very hard to break blood brain barrier.
Can the glymphatic system be abused to make medicines enter the brain rather than be ejectex from the brain?
What did you study?
I wonder why we then do not have a heart-brain barrier? Heart muscle is important too. So are many other organs - for example, kidneys.
because evolution only does the bare mimum to keep you alive long enough to have a high chance to procreate

Then why in the world does obvious junk like meth, cocaine, heroin, LSD, etc. etc. so easily get pass the BBB?
