- Mutations in the CFTR gene, which encodes a transmembrane ion channel, cause mucus buildup in the airways of patients with cystic fibrosis.
This animation can be used to illustrate the connection between genotype and phenotype using a human disease example. It also demonstrates how knowledge about the genetic mutations responsible for a particular disease can be used to develop a treatment.
Cystic fibrosis is an autosomal recessive disease caused by any one of more than 2,000 mutations in a gene that codes for the cystic fibrosis transmembrane conductance regulator (CFTR). This protein functions as a channel that transports chloride ions across the membranes of cells that line airways, glands, and the digestive tract. This animation shows how some CFTR mutations prevent the channel from functioning properly, leading to the production of a thick mucus that can obstruct airways and provide a breeding ground for infections. The animation also illustrates the process by which scientists identified small molecule drugs that can improve CFTR channel function and treat the disease in some patients. - Věda a technologie
My child was diagnosed six years ago and I’ve never seen anything with visuals that are this clear and with such succinct explanations. The CF clinics should use this for newly-diagnosed patients.
Sorry but can i ask how is your child now ?
This is an amazing visualization of what is happening inside the body of an CF patient. Thank you.
Your videos are absolutely beautiful. Well done on the quality, keep these up. My students receive wonderful visuals with the help of your animations.
the visuals are mind boggling
hats off to those editors who made this for us !
videos like this are why i love medicine !
Cant believe people would hit thumbs down on this
Probably because they were forced to do this, lol I was, but I thoroughly enjoyed this and really appreciated the high quality images in it, so I'm not one of them!
Because this video is TERRIFYING
But none did
Great explanation
This is the best, most succinct visual explanation of CF I've ever seen. Thank you!
You're very welcome!
😺 Remarkable development in understanding this dreaded condition. Education and intelligence combined to great effect!
Incredible video, I really liked it. professionally speaking I'd only add a bit of information on the different types of protein mutation, meaning the different deformed protein channels that can arise. All the rest was just great!
This is a very clear explanation of CF! Thank you
Glad it was helpful!
awsome animation!
Incredible visuals
Cleared my concept🙏🏻😆
Wonderful animation...
What an amazing animation
Thank you for this video. 🙏
Just like this, understanding CF has become easier. Thank you!
Thank you so much! I’m doing a level bio and visuals help a lot with understanding ❤
Wowwwww👍👍👍👍👍 loved it
Just fabulous
Awesome explanation..
amazing animation
Ty nicely understood
It's amazing the human body works at all.
What a nice video OMG
👏👏👏👏👏👏👏👏👏 nicely explain 🙏
Great explanation with beautiful visuals.
Glad you liked it!
Researchers tested over 200,000 small molecules to see if any of them would bind to the CFTR protein. Then for each small molecule that had some binding ability, researches chemical synthesized different variations of that molecule and tested them. They identified a drug that when taken by patients with a certain type of CFTR mutation, binds to the CFTR protein, opening the channel and allowing improved ion transfer. This increases chloride ion flow and maintains a watery, clear mucus, which helps the cilia move more freely and reduces the risk of bacterial infection.
Please upload more videos
Amazinggggg videooo!!!!!
wow , well-explain video!! keep up the great job!
Thanks a lot!
Epic
Great
Human body is amazing
Thanks a lot! The video is very interesting and educational. I wanted to know if it is possible to subtitle it in Spanish.
It is definitely on the short list of resources that will be translated to Spanish. I don't have a timeframe for when that will happen, but it is in the works.
wow, thank you :). I read half of two papers about CFTR and still didn't get how it's regulates water, because the paper was too in depth about signaling cascades and localization in apical membrane. I still didn't get how it regulates water. But, I just found the answer from this video, through osmosis and salt regulation. I'm too dumb to remember that aquaporin should exist everywhere in membrane and yeah, salt attracts water. And water can pass through this channel right?
water will go through the aquaporins not the Cl- channel/CFTR. and yes the slightly positive hydrogens in water are attracted to Cl-
so why Cystic fibrosis Have Stomach Problem And Why They take Medicine Before every meal?
I am suffering with severe cystic fibrosis, nasel polyps and lung infections..
I need the medicine that is made after research on this..
Can you provide me?
Anisa, have you talked with your doctor about Trikafta? It was just approved for 90% of CF patients and has shown incredible results!
Tobramycin bid...u want ping me
I’m so sorry you’re going through this. It all depends on your mutations, and you would need to discuss with a CF doctor. CFTR modulators is what they are called. The mental health side effects from the drugs were so bad we had to take our daughter off.
Hello and good day.. I am Dr. Chaey Rellegue of DepEdTV Philippines. I would like to ask permission if we can utilize some contents of your video for educational purposes for our senior high school learners? Thanks and more power

@@biointeractive Thanks you so much.. More power to all of you.
Thhhhhaaaaaannnnnxxxxxxxxx
I have CF and there is no available cftr modulator for my mutations 😭😭😭😭😭
❤️
Great animations. But the drugs name? Find out in the next episode of Dragon ball Z
Jk it must be ivacaftor or lumecaftor if you wanna know
Wait ..so the water will move into the cell?
Yes, the lack of chloride transfer leads to the cells absorbing water via osmosis.
Keep in mind the way you get bacterial infections is caused from your own microbiome as apposed to environmental issues
We got all the way to the end for you not to tell us what drug will help us😂
Mr Burns Biology anyone?
the video image is too poor, you need to fix it more
cool cgi bro
Why not tell us what the drug is called 😅
we all should drop our religions and gods
and worship those people who always make molecules like that !!
no joking !
