Hypersensitivities - Types I, II, III, and IV (Hypersensitivity Reactions)

[@jesusistruth.sthazel-adaug3279]

My 70 powerpoints transformed into a 11 mins video. Thank you so much professor.

[@BiologyProfessor]

Happy to help :)

[@ferrislkpokpa7867]

The self-confidence is really expressed in your face, that's a sign of a good Teacher.

[@BiologyProfessor]

Thank you! My confidence in my teaching has definitely improved with practice. :)

[@Alimohammed_33]

I agree👌🔥

[@kendallphillips3297]

Thank you! This helped a lot to narrow down all of the nitty gritty information into something understandable.

[@Pkedya2boy]

This was very helpful for numerous reasons. My professor never really slowed down to re-iterate the simple things such as "IgG and IgM recognizing antigens on cell surfaces." This really helped to simplify the 4 steps of hypersensitivity and my poor understanding of immunology in general.

[@BiologyProfessor]

Glad to help!

[@BiologyProfessor]

Here’s another immunology video that might help you. It’s over antibody structure and function. ruclips.net/video/a-gmb2avW38/видео.html

[@daniellakucherina1663]

very straight to the point and simple. thank you!

[@pksaini4781]

Helo?

[@Shindler39]

I hope your life is going well for you Daniella.

[@michellepellegrini1271]

I am taking Patho right now and found your video and let me just say that you are going to help me remember the 4 types of hypersensitivity. Thank you! This is a great video for visual learners like myself!

[@MD-01]

beautiful video. GOD bless you. the fact that you were able to make it this simple confirms that you actually know the stuff. unlike those complexity loving professors that makes lives of knowledge seekers hell on earth. this lady actually made me love the hypersensitivity reactions

[@lindseyduncan3574]

Thank you for explaining that so simply. You are a wonderful teacher!

[@sandeepjat6825]

Hi

[@JelvisChristley]

As someone with food allergies and rh reaction as well as diagnosed antiphospholipid antibody syndrome and a type IV expression of erythema nodosum, I wanted to say thank you for helping me to understand what is breaking down. I now understand why my hematologist suggested I undergo experimental immuno suppressive therapy. It gives me more information to make the appropriate decision to move forward or not.
So
Thank You ❤

[@ak2944]

This was really helpful, thank you so much! I especially liked that the key-words weren't written in, so I could check what I remembered.

[@mercychepkirui1123]

Thanks mum ...I've understood it well ,be blessed

[@sakthipriyakurmapu9383]

Concise and to the point. Really helpful for a medico! Thank you!

[@lcdp9459]

This has been the easiest breakdown for this topic. Thank you! 💜

[@AminMohammadAmini]

I had never seen such a good video before for hypersensitivity

[@rsonlinebiologyclasses7697]

Muhammad bin tuglak.

[@Quranrecitation.Quranlofi]

I have wasted time hours by hours to understand the hypersensitivity
But this 11 was enough,,,if I would find it
Thank you professor

[@3bdulaziz197]

Thank you for this video, it summarizes a lot of information.

[@NERVESMEDICINE616]

Exactly 👍

[@user-xu8pt6uy8h]

I have been reading it for 3 hours. And then I have found you and you have made everything clear. Thank you my dear ♥️💐♥️♥️

[@Army-1pl1og1y]

أخيرا انا فهمت درس hypersensitivity, شكرا لكي حقا❤❤❤❤

[@rickfearn3663]

Excellent clarity.

[@laythalashraf1213]

Nice simple
We need more examples about diseases caused by every type of hypersensitivity

[@Danamoss100]

Simplest and best explanation ever. Thank you !!

[@BiologyProfessor]

Thank you so much for watching! I really enjoy it and I hope that my love of teaching is easy to see. :)

[@oswardelias8479]

thank you so much i understand simply God bless you

[@SAKtownAli]

Perfect. Shared with my classmates. Thanks

[@hofstraabhu]

Great video, very helpful. I have a couple of questions.
1) what causes the "delay" in Type 4 reactions?
2) why do some allergens elicit a Type 1 reaction while others elicit Type 4 reactions?

[@BiologyProfessor]

1) In Type 4 reactions, the delay is caused by the time it takes the immune response to occur. Antigen first has to be taken up, then processed, and then presented by antigen presenting cells. The T helper cells that recognize the antigen are not very numerous in the body and they take some time to arrive. Together, this adds to a bit of delay in immune response.
2) I believe the correct answer is that different kinds of receptors are triggered by different kinds of antigens, resulting in different types of responses.

[@jonathanwalker7199]

Impressive explonations

[@BiologyProfessor]

Thanks

[@NotGemFN]

Loved the video....Easy to understand...
Could you do a video on MHC ?

[@BiologyProfessor]

I've added it to my list, thanks!

[@shadowman7408]

Excellent video, just brilliant. Would Metal allergy and multiple chemical sensitivities and sick building syndrome be Type IV then?

[@yahyaadam3136]

Well presented, excellent!

[@daltonrollison]

Rh factor is a protein

[@BiologyProfessor]

You are correct

[@reshmamariam324]

the lecture was awesome but i m here again to see my new CRUSH

[@InsightfulScience]

Thank you very much!

[@AbdulazizMaiof]

Thank you for the video.

[@soccersbk]

Thanks, great video!

[@jmcs2033]

This is great. Im currently doing a presentation on food allergies and I'm working on the mechanism of how it happens, and so would you say then a peanut allergy is considered a type 1 hypersensitivity?

[@optikalillusion777]

Yes. Any anaphylactic type of reaction is a type 1 hypersensitivity.

[@user-yf8hs3ct8i]

thank you teacher

[@imadwalikhan]
