- What is type II hypersensitivity? Type II hypersensitivity is an immune response in which host cells are damaged due to antibodies binding to the cell surface. Find our full video library only on Osmosis: osms.it/more.

just a summary...so i can come back and revise too
Type 2 hypersensitivity
mechanism of action:
1.Activation of complement system: C1 binds to Fc portion of the antibody. Activated C3,C4,C5 - atrracts neutrophils, degranulation, cell lysis.
2. Membrane Attack complex - disturbance in osmotic gradient - cell lysis
3.C3 associated opsonization and phagocytosis
4. ADCC - antibody dependent cellmediated toxicity - NK cells
NONCYTOTOXIC MECHANISM: Antibody mediated cellular dysfunction.
eg..Graves disease, myasthenia gravis.
Come back and revise it for the 31st time. xD
I cant believe how specific these videos are. There's more detail in this video than there is in my lecture notes lol and I'm in second year of uni.

Very creative 😅
4:38 I adore the sound effect when the cell bursts, it's so damn satisfying!
I'm currently in medical school and am very happy that I found your channel! Thanks for simplifying so many topics in such simple ways!

These videos are so helpful that I feel bad for all the medical students who had to learn these materials without the Osmosis’ help. I feel very fortunate!!
You guys are awesome! Putting these videos together helps link everything we learn into a smooth progressive piece to remember and understand processes better. It makes the various lessons on a subject cone together into a whole. Thanks SO MUCH!
Thanks!

Give thanks to youpeople this video has really help me.ready to write my exams tomorrow

well explained..I've come across this channel for the first time as it's a recently launched one..but I must really appreciate u people for both the quality quantity of videos you have put up..n the best part is that u give a broad overview of the topic in a short time using simple animations..this is especially going to help the students correlate and interconnect various topics..thank you..n keep going.

It was helpful thank you
Very clear and well explained video !! Thanks a lot !!💪👌
Glad to help, Apelel! 💫 🥰 💖
You guys are great, I have a friend of mine that is always recommending you to me and here I am, listening to his advice. Just wanted to drop this comment about 3:00, the complement proteins (C1q) does not bind to the Fc portion of the antibody, rather it bind to the antigen binding side which is found on the constant region of IgG and it is above and different than the Fc portion.
Can you share with us a credible source that supports the correction? Thanks!
Hello, I just double checked from many journals articles, what you have said is true. The Fc portion on an IgG is divided into two compartments, upper one for complement and lower one for membranes or receptors. Thanks for your reply.
good tutorial...
Good gob and I really thank you so much 🙌🏻👍🏻
But the only think I want from you to speak slowly
Because you are too fast when you’re speaking
Good job and thank you so much
Thank you very much dear
Lordy... I love these videos.
Thank you

Thank you very much, for making these videos they're really helpful.
but in case of myasthenia gravis I looked into different sources and I found that actually the complement system is activated when the anti-AChr is attached to the AChR and it leads to decline in numbers of AChR
Could you share with us those sources? Thanks!
Thank you Osmosis 👏
Our pleasure, Rukiee! 😊
lovvvvvve osmosis channel. yet dont know the definitive difference between diffusion and OSMOSIS. but lovvve this channel. LOL.
Osmosis is the diffusion of water. Diffusion is the diffusion of solutes. They both flow from high to low concentrations, which means they often flow in opposite directions from one another. The water will flow into the cell, whereas the solutes will flow out of the cell for example, all in the process of equalizing concentration gradients.
Thank you so much for making such useful videos. After seeing these videos topics seem to be very easy.
You are most welcome, Kherde! Glad to help! 😊
Thank you 😍
You are great!
Pls any video on type IV
