- Along with the skin, the gut mucosa represents the first line of defense against environmental factors. In the gut mucosa, a recently discovered type of lymphocytes called innate lymphoid cells (ILCs) maintain tissue homeostasis, orchestrate tolerance to food or commensal bacteria and contribute to immune responses to pathogens.
This Nature Video shows the complexity of ILC biology in the gut mucosa at steady state and disease.

Amazing work. Although I am an immunologist, the helminth clearance, just surpasses me. Congratulations, your endeavor simply is the strongest motive for any young scientist. Wish I had TH-cam during my bachelor studies.
How are you ?
please make more videos about the lives of cells. this is incredible
Now that is quality beyond anything you can imagine possible
And this is why i love science!!!! Microscopic responses are always going on in and outside of our bodies!
and untill you study medical science won't really understand it all but once you do trust me you will feel like a damn super hero with all that amazing knowledge
btw im a Paramedical Esthetician and even though its a specialty in skin care i did understand what this video was talking about, The body is simply amazing!
RIP to us medical students with an medical immunology exam in a few days.
Mine's in 10 days don't call me out like this
I have an undergrad immunology exam tonight!
how did yall do?
i have one tomorrow T-T
This is the most amazing thing I've ever seen. Do other people drool over molecular biology like I do?
If you think about it, this is happening right now in our bodies
so i have been binge watching on cellular interpretation and am now in awe of the complexity of our immune response system. i can not believe that we have evolved into this magnificent entity and we have no idea who we are under the skin. i know that doctors and scientist already think this is boring stuff but holy shit!... i had no idea. mind blown!!!!!!!
And to think it only took 3½ billon years to get to this stage of cellular complexity.
I'm amazed by the fact that there is a class of molecules that are called alarmin
Alarmins are actually just normal cell peptides that are not normally found extracellularly. Because they're only meant to be found inside cells, when they're sensed in the tissue by immune cells its clear that cells have been killed.
Alarmin as of when these molecules out of the cells as a "danger signal" to others.
Yes, I know. Still cool to call these alarmin :)
@@mrniceguy4277 Yes. You can search out DAMP and PAMP for further reading.
@@fara.r.8181 I'm a PhD student with a M.Sc. in Immunology, mate :) Still a good tip in case some random person reads this xD
Going for quality explanations like this is the way, the way to get better doctors and scientists which are less confused about their knowledge and so can make easier the next steps in the medical science.
this is such a beautifully made video, thank you for the clear explanation!
Superlatives are well-deserved here. Amazing work!!! Pleeeeeease more!!!!
Full transcription
Our body is in constant contact with environmental factors. Epithelial barriers like the skin or gut mucosa represent the first line of defense in the gut mucosa specialized immune cells actively reinforce the barrier and induce tolerance against food or commensal bacteria. Among those immune cells a recently discovered type of lymphocytes called innate lymphoid cells (ILCs) orchestrate immune responses and maintain tissue homeostasis. Unlike the T and B lymphocytes, ILCs do not express adaptive antigen recognition receptors. As such, their activation and expansion is not driven by antigen but rather by cytokine signals from the tissue. ILCs come in three types: ILC 1 / 2 / 3. ILC 3 interact with dendritic cells to maintain the epithelial barrier. Dendritic cells which are specialized in the presentation of antigen, acquire antigen from the gut microbiota and secrete IL-23. IL-23 stimulates the ILC3s to make IL-22 which then activates the epithelium to secrete antimicrobial peptides or AMPs that kill bacteria directly. IL-22 also enhances IL-23 production in dendritic cells. This dialogue between dendritic cells and ILC 3s maintains the barrier against pathogenic or commensal bacteria. ILC3s also interact with macrophages to establish tolerance towards the commensal microbiota. Antigen from gut bacteria induces the inflammatory cytokine IL-1β in macrophages which in turn triggers the secretion of GM-CSF in ILC3s. GM_CSF signals back to macrophages to induce retinoic-acid which promotes the differentiation of regulatory T-cells. Regulatory T-cells are essential in maintaining tolerance towards the commensal microbiota. ILC2s contributes to responses against helminths. These parasitic worms release enzymes that digest the mucus barrier and cause massive cell death. Epithelial cells sense the danger signals released by the dying cells and produce alarmins (IL-25,IL-33, TSLP). In response to the alarmin IL-25, ILC2s make mediators that induce mucus production from goblet cells, send activated dendritic cells to the lymph node (by IL-13 secretion) where they can prime T-cell effectors, recruit eosinophils and mast, and induce muscle contraction. These actions results in the expulsion of worms from the gut. In response to IL-33, ILC2s also make Amphiregulin, which induces tissue repair following worm clearance. However, ILCs also contribute to tissue pathology. ILC 1s which make the inflammatory mediator IFN-gamma and ILC3s which can acquire the ability to make INF-gamma during chronic inflammation are found in inflammatory bowel diseases such as colitis and Crohn's disease and contribute to gut pathology. As such, ILCs participate in various aspects of immunity from maintenance of the epithelial barrier and tolerance against commensals to immune responses against parasites and pathology associated with chronic inflammation.
did you trancribe it by hand or with an app?
@@julianschachter2262 By hand
this makes me so happy for some reason
Obscure but crazy beautiful
Had this been available 40 years ago I would have likely not switched from pre-med to poli sci...Never too late to learn.
absolutely fascinating
Marvelous animation, great narrative. Serious problems with the closed captioning, though.
Incredibly well done
amazing so complex system going on in our bodies 😊
a piece of art
Insane animation.
Great video ❤ please keep making videos like this ❤
I want to become a scientist now
What an Amazing video... #after read so many writings and in a deep of lack of knowledge this video makes it brief clear!
Estou encantada com as animações espetaculares presente nesse canal. PARABÉNS!!!
Perfect!
I love this work, it feels like you are watching a movie 🎬
Super explanation and animation ❤️💙💛
3:10 What about peyer's patches instead of a LN?
These videos and the narration are so helpful. Spell-binding.
Amazing❤❤❤
This was so intense😰I loved it
Fascinating!!! Thanks for posting :)
cool animated videos plz dont stop making videos like this
wonderful , thank you
This is beautiful. I study the immune system / tolerance and exhaustion /and always open to collaborations. Best,
Excellent! Many Thanks.
It is very amazing thank you
So good I "almost" get it !!
*****
Nooo.. that was helpful ... the problem is that I am 71
Lol 😆
thank you very much
Beautiful!
Helminthic worms also evolve to counteract the gut's defences. Thus, how effective is the current stage of human gut evolution vis-a-vis helminthic worm evolution; are we ahead or just equal?
This is amazing....thank you so much🥰
Amazing what we don’t know.
I could watch videos like this on every single subject inside of biological creatures. This is like a version of the magic school bus haha
thanks ad
please make the video on MHC pathways
Fantastic !
Good video👍😉
Excellent video. 👏👏👏
so many interleukins,,,,,, cries
I love this work and appreciate your efforts to make this | ❀ ☆✿♡
Good video
Simply great channel. I subscribed.
A replica of the universe
Maravilloso
Please explain the work of the enzyme 5 alpha reductase in changing the male hormone, and where it is produced. Thank you.
Amazing!!!!! 👏🏼👏🏼👏🏼
Strange to see when a cell fires signal molecules directly in direction to an another cell. It is wrong visualization
awesome videos
Informative
AWESOME 👏🏽
Anyone else sent here by Jenny/A Kelly?
hi everyone hope all are keeping fine .reactive population of lymphoid cells pls help us how to overcome with lymphoid cells what is best treatments ? thank you very much in advance ,
Is it a similar situation in the lung?
