- Animation exploring a signal transduction pathway that induces Apoptosis.
Published "Molecular Animation of Cell Death Mediated by the Fas Pathway", Sci. STKE 2007 (380)
Sound design is intentionally horror, as you witness a diseased cell self-distruct.
Inspired by "Alien" and "The Shining" - Наука та технологія
Why aren't educational animated movies to this quality more common? I love these videos, it's nice to visualize the knowledge we have but can't observe with our eyes.
Because people will start questioning a random based origin of life
Probably because of the existential dread that comes with knowing that all life will die within 0.00000000001% of the entire time the universe exists before time becomes meaningless thanks to Black Holes and possibly Proton Decay.

Thanks for the compliment. 😁

I am dumbfounded by the complexity of this thing
I am awfully dumbfounded by The greatest GOD who created the complexity of this thing.
@@King-Salem you really shouldn't mention god in a scientific video
@@faiqaalmutairi2105 shut the fuck up herpes dipshit
@@muffinandcake5247 I said the truth only. Do you still believe such complexity was made by itself?
If yes, I would agree if windows 10 was made by itself.
As a programmer, it is IMPOSSIBLE for me to believe that this complexity was made by itself.
@@King-Salem if a complex being requires the existence of God as an answer. Then what is the explation to the existence of God. Did god created itself? If so then where is the consistency? It seems like your logic is flawed
People are impressed by the structures themselves, but what always impressed me the most was how these pieces fly around throughout the vast space of the cell and zero in on the correct areas with extreme precision, and with no visible mechanism to bring them together. What makes it even more impressive is that 85% of the contents are edited out in these videos. So what looks clear and open is really quite densely packed and extremely active.
I mean it's that crazy, you could imagine them like magnetic puzzle pieces, where they go around attaching to whatever is near them, but only if they fit. Each protein and enzyme is made to fit with another to do some specific job. Although you are correct about the contents, it would be completely filled with other molecules not shown for clarity sake.
*Edit: never mind.*
The interior of a cell is not exactly a "vast (empty) space" - unless, of course, if we only care about the nuclei and electrons; in which case, everything, even solid objects, are "vast empty spaces" - but, like the first replier said, it is filled with other molecules that are not shown _for clarity's sake._
Well everything is orchestrated by gene expression and then of course organelles allow compartmentalisation of biochemical processes and molecules, so it’s pretty organised and quite crowded living space. Cells are quite compact rather than vast.
It's also the chemical encironment such as the pH, chemical gradients that also plays a role. It is not in.vacuum.
>no visible mechanism

It's two dofferent signal pathways described here. The one started with the T-cell is the extrinsic pathway, the one induced by cytochrome-c released is the intrinsic pathway. They both result in caspase-3 activation and protein and cytoskeleton cleavage.
I too missed a clear distinction between the two because now it seems like it's all one process. But then they also could include the Bax-part which triggers the release of cytochrome C :)
and what happens w the bubbles? they travel freely in the interstitial space??

This is covered on the last exam in cell biology. Kind of sad to see the thing you have become so attached to throughout the semester kill itself, lol.
Rest assured it does so for a very good reason. The main reason is an error while replicating. Apoptosis is a safety measure by the cell to ensure neighboring cells or new cells produced by it are not harmed
+Unkempt Whizard look I'm doing a cell biology module now, exam is in 2 weeks
***** good luck!
Unkempt Whizard lol thanks I'm going to need it
@@sarcomak982
Would an "error in replicating" potentially caused cancer cells?
Or is this for any sort of virus/infection?
The sound design on this is other worldly.
The poor cell was bullied into suicide by the T cell smh, we live in a terrible world
I️ want that cell to know that it was a beautiful cell and nobody can tell it otherwise
T-killer is a kinda policeman or soldier, there was no bulling by other "regular" cells. But yes, apoptosis can be initiated by other reasons, when the cell somehow causes damage to the organism. For example, neuron can kill itself when it translate too much signals.
@@keaganhesse8005 Imagine having cancer cells lol
Think God is aware ?
It just disassembled itself. Wandering what happened to those bubbles left of it? Absorbed by other cells? Or removed from the body?
Really kind of sad to watch, but very impressive. How amazing our bodies are... Also is it just me or would "Death Ligand" be a great name for a band?
It's also mind-blowing that we personify the "life" of the cell as ending but really it's just atoms and molecules reacting to one another. How "life" figured this out is deeply perplexing.
@@XFz2nLDWo73x95 Yep! I see everything as interactions between atoms, but it's at a higher level..
Dibs!!
@@XFz2nLDWo73x95 can the same be said at the macro level with humans in general?
Hmmmm.
Simply mind blowing what the body does.
It seems so apocalyptic.
apoptocalyptic!
Apopcalyptic
It is.
For that cell, it is the apocalypse. Also "Apoptosis" is a good band name.
Cells are so awesome!

Exceptional work! Hats off to the entire team, particularly the animator.
I had apoptosis once but I cured it and now I'm immortal.

Go back to Reddit.
Was this directed by David Lynch?
My first time watching a cell die.
Be strong
We love this animation of the apoptotic cascade! It is a very helpful training tool for our company, which specializes in apoptosis and caspase assays. Thanks!
So mind-boggling. Again, thank you all so much for bringing this to us. It really is amazing to see a “death ligand”. ❤️ all the videos, it is so fantastically complex!
All this work being done Unbeknownst to us Is simply amazing.
This is so freaking amazing, the best way to learn it visually!
I can't explain it, but there's something that feels almost sacred about programmed cell death
This almost felt like I was watching a horror film - creepy!! But excellent animation and really helps bring the story to life.
I'm studying apoptosis at the moment in my course and having to write at the mo about cascade 8 so this is helpful to visualise things, I love this type of visual aid. Love the animation many thanks.
i cried watching this T.T
This seems a lot like a very complex 3-dimensional cellular automaton!
Fantastic! I've been learning about Apoptosis on Coursera and this video really helps me to understand the process.
It's amazing how tightly controlled this process is
What an amazing video! Thank you for sharing!
Brilliantly done! Many thanks
4 minutes of flying dip n dots
thanks the video was very informative :)
but is it just me or was this really scary ?? :D
it was a bit. lol
Its scary, because its supereffective and merciless...like a machine.
Because sound effects are really cripyy
an absolutely awesome video - thank you!
Thank you so much 🙏🙏 amazing representation 👍👍👍
This is literally one of the coolest videos, ever
why is the music so ominous
Your video is just amazing. I cannot even explain your perfection in words. Thanks alot for sharing such a nice video 👍👍👍
So there are two pathway shown here. The first one was the extrinsic pathway activated by Killer T cells and the second was the intrinsic pathway which is activated by p53 activating the production of BH3 proteins which form a channel on the outer membrane of the mitochondria which allows for release of cytochrome c. Apoptosis ends with phagocytes eating the bleb or little vesicles at the end. The phagocyte should have been included because apoptosis leaves no trace of the cell behind after it is destroyed. This is a big difference between apoptosis and necrosis.
Excellent presentation beyond the limitation
Love it how it shows the complexity of cell death beautifully...
This youtube channel is still the same😊😊thanks for being consistent in all these 12 years.
Since 1998...

God, this is like the cellular 10 plagues. Perfect sound design
Im studying this and wow the simulation really makes it feel more real if that makes sense
Anyway great video 👍
I LOVE the sound effects! My cells sound just like that, too.
One thing i guess i never considered is that the cell membrane is still hydrophobic, which is probably how a lot of viruses can end up having their own shield of protein or other means of reproduction even after the cell has been destroyed. But thats very clearly shown here with how the cell still tries to keep its form even after its "popped"
Love these videos. Yet, I can see how it can be difficult to follow if you're not familiar with the process already.
Wondeful Biochemistry with many details!
awesome!!! great job guys, thank you so much
Amazing video, my best compliments to the authors. I highly recommend to watch it while playing the video "Craig Armstrong - Escape (Full Version)" instead of the original audio, it becomes much more emotioning! =]
2:27 amazing sound choice
I like how the mitochondria is just... "We're dying? Alright, I'll make it faster"
*Mitochondrion. Mitochondria is plural.
@reg gen ...there’s multiple mitochondria doing that so it’s plural
These animations are SO GOOD!!
Amazing simulation
Coolest video I've seen this year! I love Biomedical Science, thank you!

Oh my goodness. I've just found the best channel on UA-cam 😍😍😍
Great! Thanks for making.
Very informative. Thank you.
Why it feels like I'm watching a horror movie and there is an intense death scene and the back sounds are effecting in its way.
Wow! That was incredible
AMAAAZING. Makes me want to take a college course on micro biology
Anyone else get shivers from watching this? My face felt tingly...
For some reason this is really, really scary. Great vid though, really eye opening!
I am writing a book TBI - A clinical Approach to Diagnosis and Treatment. Find me at tbimedlegal and have spent the past 6 weeks reading articles on Apoptosis, Necrosis and Authphagy. Your film is excellent and makes sense. When I return to Melbourne with Pathlabs, I owe you a tall one for the efforts and accomplishment... Excellent work..
U guys are brilliant
Great animation folks! I'm using all these animations to study for the USMLE, haha! :)
Amazing video, liked so much.
Also the comments section feels like home
Gave me a major horror film vibe. Awesome stuff.
Good work!!
Amazing!
Very good illustration about how a bad cell dies by associated proteins and substrates activation for initiate apoptosis.
Great video!!!
What about the caspase-recruitment domain (CARD, subunit on caspase 9)?
Beautiful
fantastic video
this straight up gives me anxiety but I can't look away
i stumbled this video, and i'm no biology enthusiast, but those animations are much better than anything pixar has ever created.
What a masterpiece!!!
This is amazing!
This video needs more views.
the best audio
How does Caspase 3 cleave the actin cytoskeleton?
This video is amazing!!!! very very beautifu
Mind boggling!
stunning
Thank you,good video
Incredible 👏👏
Great animation! Weird sound effects. Are there even sounds in this small scale?
No. The sound effects are added to help the viewer understand what is happening.
What always is hard for me to get is how there are so many of any particular protein saturated in an area so that these things can happen. Like how are there enough of those proteins that destroy others just floating around for them to activate? Or the ones that initially bond to the death protein from the T-cell. Even in things like RNA transcription, how is there enough tRNA in the area for every amino acid. How is there enough ATP everywhere? How are there enough DNA bases floating around in the nucleus. Where do those DNA bases even come from, afaik they arent made by RNA and ribosomes?
What becomes of the post-apoptotic cell? Do the vesicles just hang around or are they removed and excreted by some means?
The remains of the cell are taken up and digested by surrounding cells and the immune system
great video with great sound effects !!
but doesn't show how the CASPASE3 clives ICAD activating CAD and how CAD fragments the cromatine..
It was very helpful for me because scheme from my handbook wasn't clear.
What logic element or method causes the KT cell to move in any direction and then find the cell that must die?
What logic method produces the signal from the dying cell to show that it must die?
My guess is that the diseased cell secretes chemicals that the killer t cell kind of smells and follows the concentration gradient towards the diseased cell
FASCINATING !!! 💥💯💢💫💫⚡
Que animación más bacana, ojalá todas las clases de ciencias en los colegios, fueran así de gráficas.
Terrifying yet fascinating...
Caspase 3 is activated two times one by caspase 8 and in the last by apoptosome Please clear Why function of Caspase is different in two activations. 1.53 and 3.31 Please guide.
Thanks
Caspase 3 isn't activated twice, the video just shows two different pathways of apoptosis (the first one with the T cell is called the Extrinsic pathway, the other with the mitochondrion is called the Intrinsic pathway).
@@regulate.artificer_g23.mdctlsk thanks
