A mental hook to try and help you remember the CD proteins:
CD4 - "It's here 4 you" - Helper T Cell
CD8 - "CD HATE", It HATES the infected cells and tries to kill them - Cytotoxic T Cell
You Sir, are a legend!
Abominatrix650 very nice
cd8 cytotoxic t cells are called T-killer cells; another CD8 are the T-supressors(they suppress the B-cell proliferation) and the variation T-helpers that interact with the hemopoetic stem cells and control differentiation and proliferation are called T-amplificators
proliferation of B-cells to be specific
I love you
You helped me pass my math exams in highschool, and now you are helping me pass my histology exam in medical school....seriously, is there ANYTHING you don't know?
what do u do?now
@@DrHazi are you a medical doctor?
I learn more from these videos than my university classes….
+Xao Vang exactly....!!!

¡Im Mexican and I find this offensive lol!
Education is outdated needs to be revised and optimized.
No kidding.
You seem really proud of your wife :)
There are infact 3 types of T cells 1) Cytotoxic T cells CTL (CD8+) cells 2) T-helper cells (CD4+ Cells) and 3) T-regulatory cells also know as suppressor T cells or Treg (FOXP3+ CD25+). Treg cells are very important cells because they are required to suppress activation self-reactivity, and prevent autoimmunity.
nice clarification, my pathology book actually just lumps together suppressor/cytotoxic T cells
There are also NKT, γδ T cells and memory T cells.
Bodh A thanks
in high school I saw khan, BA in chemistry I saw khan, Now, pharmacy school still seeing khan. Conclusion, you are like my longest lasting friend! Thanks man, for what you do for human beings.
Lol I'll never forget this because your wife put you in check, looks like you got yourself a great match, behind every great man is an great woman making sure he isn't screwing up his terminology 😂
I know i already said this but you rock. You saved my life on this test. Thanks dude
I want to thank your hematologist wife for clarifying the term "plasma cells." I was so confused when you kept saying "effector B cells."
Same here i was like please say plasma Cells I have exam on Immunity in 2 days and here started doubting my understanding of the whole thing thanks wife
i love the way you say immune system. IMMUUuuuUUne system
helpful video as always. 2nd year at medical studies , you're the best really , thanks a lot!
I used these to study for my MCAT and now I'm still referring to them to supplement my coursework for first year of med school. Great stuff!
I'm taking pathophysiology right now for my undergraduate major and this video is so so so so helpful. THANK YOU SO FREAKING MUCH!!!!!!!! you explain everything incredibly well and make it very easy to understand!!!
That's amazing video from the teaching point of view and yes, it is so engaging that you can never get bored viewing it over and over! Thank you.
those vids still save life in 2019 ! Thanks
im so glad your wife expressed how effector cells becomes plasma cells because my professor never used that term and i had wrote inside my notes that they were the same. thanks for sharing. you are a genius!!! i have so much studying to do, but i couldnt study unless i understood what was going on. You are so appreciated!
I learned more from these videos than I did from sitting in class. Thank you!!!!!
His voice is so familiar, so soothing, so comforting. I love it.
Just wanted to say that you make these very very well. As a student in an accelerated program and who is very visual, this kind of presentation was very effective. Thank you so much for letting everyone learn from you. After seeing this, I wonder how I got through my undergrad without teaching formats like this!
your saving my life right now!! thank you
are you kidding? this guy nails it. I can finally understand this stuff
This guy is awesome with his videos :) love them!! Seriously it is this series of videos which actually make me not want to "shoot" myself every time I start studying biology!! Thanks Salman :)
This is really helpful. not only did it make it easier to understand in a conceptual way, but also in a visual way. Thanks!
Currently preparing for Immunology Viva Voce - This content is absolute fabulous & an insight to how simply processes and mechanisms can be explained when one has a clear understanding
Been watching your videos since first year of nursing. Now I’m doing my post-graduate studies and still learning from your videos! Thank you !
He has clarity in his explanation. I find it easy to understand when he explains not others even though it may be from Khan Academy.
People says they learn here lucidly than university, there should be a RUclips University.
too right!
The amount that I have used your videos the past couple years is unreal.. mostly physics and bio but you have actually saved my ass so many times and I thank you!!
I recommend you to everyone
You are the single reason I got an A on my immune system unit test and as a result a 90.4 for the entire marking period. Thank you, Mr. Khan Academy man, thank you.
I wasn't sure if I was understanding the interactions of T and B cells until now, but now I know I was understanding it correctly! Thank you! You are a great instructor :)
God bless you so much for this.. You just saved my midterm final exam!!!
I meant Midterm exam !! Thank you!!!
+Akinbunmi Damilola I can send you notes. I have a teacher who met Crick and one that knows many Nobel prize winners.
Guillem Estivill yes plz
Thank you so much I have been fighting with Immunology for 2 days! This certainly cleared some stuff up.
I'm from Morocco, I study immunology in french, I understood your explanation much better!! thank youuuu
Extraordinary!
Thank you!
thanks so very much. this vid has made me feel so much better about immunology!
Agreed...why aren't we paying this guy! He is awesome!
Pre-Pharmacy and taking Microbiology. This is very helpful 🙌🏾
Thanks! I don't know why but it seems way more efficient and it's easier to understand if I were to watch videos on RUclips compared to listening back to podcast provided by the university. This video helps me a lot in consolidating my understanding about immunology.
Very helpful. The clear explanations you give are easy to understand.
This was so helpful! Thanks!
I love how he called the cells people at 9:58, So awesome....
WOOOOHOOO I i finally understand this topic! gosh i dreaded opening my book to read these mechanisms! i understand so much better now! hey you have prob heard this millions of times but THANKYOU! THANKYOU!!!!!! right im so going to get that A in class now!
Could you make a playlist in the order which these should be learned/taught? That would be SO helpful. Seeing how you uploaded them on the same days, it would be great to know in which order they should be viewed.
Thanks!
Thank you so much, yes you did clear it up. I understand now.
god bless you khana academy for never failing to prevent ME from failing my exams. your videos have been an invaluable educational resource in the last hours of studying. thank you thank you thank you.
Great video, its really helpful how you use all the different names of the cells to cater for the different curriculums around the world.
THANK YOU SO MUCH! this really helped to clear up the information in my head
You saved me in my immunology classes..thanx
What a great and informative tutorial. I am a vet school student and this is the perfect video to review for an immunology final! Thanks and keep up the great work. I love how you simplified this!
so helpful and clear, wish my professors could be as concise in their lectures. My notes this year are a bit of a shambles so this is probably going to save me in my exams
I was wondering about the role of Plasma Cells. This clears up few things. Thank you Mrs. Khan :)
🎉you made this so clear and simple than I've ever known...🎉🎉bravo..keep it up
I’m Williams from UK 🇬🇧 After using the medication I got from Dr Alued on RUclips now I am completely cured from HIV I highly recommend him ❤
I wish my biology class would be this good. You make it so interesting and simple!! Thank you soo much for demystifying the immune system!
Thank you so much I'm a medical student and this is a better explanation than in my histology book.. God bless you!
Thank You so much for making these videos. Im learning a lot so fast! God Bless you!!
SO GREAT!!! thanks so much! I understand so much better now!
you're such a good teacher Sal!
YOU FRIGGIN ROCK, GREAT EXPLANATION!!!
Thank you, i'm a med student and i found this very interesting !
made over 8 years ago and helped over 800,000 people pass quizes and exams for biology thank you
You do an amazing job explaining something that I thought was so complicated! Thank you so much for posting!! Very helpful!!!!
Knowing very little of the immune system I decided to watch this as supplemental information for a study posted on a daily science web page and found this video a sweet spot of a hit ;)
You are the best ........ from SYRIA
انت الافضل............ من سوريا
this is the best video i have ever watched and i emailed this link to all of my confused friends studying for pcat right now. ahhh wish me luck!!!!
one small clarification. MHC 1 and MHII proteins do not connect with CD8 and CD4 proteins. They connect with CD8 and CD4 cells respectively but through the t cell receptor (TCR).
Thank you so much, this was extremely helpful.
Microbiology and immunology exam tomorrow. Thank you my friend.
07:52 "it starts...wanting to kill things" LOL
thank you for the video! :)
thank you so much. This is amazing!! You've saved my life from the examination.
what a great video. help me clear for microbiology chapter 17 on adaptive immunity. Clear me on the T and B cell in depth. Now i cant do any wrong on my test after watching this video. thank you.
excuse me can i ask you a question, so is the dendritic cell that he drew same as the b cell??? cz both antigen presenting cells
You are amazing! Thank you so much!! I learnt like 95% of my immunology from you, and 5% from my lectures.
Thank you SO much!
Very helpful! The pictures/notes help me alot. Thanks so much! (final exam on monday)
Also, when CD4 cells bind to B cells the activated complex releases interleukin which stimulates the production of clone cells (memory cells and plasma [produces antibodies]).
More specifically IL-4 & IL-5
So glad to have found this right before my exam, been stuck for days!
You explain very very well
Very appreciated. It always helps to tie in the concepts together.
very helpful indeed!
THANK YOU!!!!, I was having such a hard time understanding this, but after watching your videos I have the "WOOOW" moment. I feel so much better to face my final for micro !!!
GREAT HELP MAN!!!!
These videos are no less than amazing. I am serious!
Thank you so much for this video. I am taking an anatomy course for summer 2 right now, and we cover so much in one day. These videos are so helpful. I wish I was related to you BONER!
I finally get it!!! Thank you!
Nice Video That You Share , So Very Nice Thanks You Review of B cells, CD4+ T cells and CD8+ T cells
Very clear and good
Awesome explanation.
love it! simply the best way to teach.
very helpful....Thank you!!!!!!!!!
wow I finally got it. Thank you. I was so lost before this video
I remember I used to make up these rules of 8 to help memorise which T cells need which MHC. So CD4 binds MHC2 because 4*2=8, And CD8 binds MHC1 because 8*1=8.
LOVED THIS VIDEO
4 people waste their money for private tutors and not remembering the best mathematician who makes a good website! Thank You, Sal.
Thanks very much, u re really good.
Really helpful!
You have earned yourself yet another Subscriber :D
pleas make more videos about immunology or even metabolism, just go on with what you're doing, its great!!
Thank you, that was really helpful! I am taking Anatomy and Physiology online and have been struggling to understand the lymphatic system because it is kind of obscure without a visual, but your videos have really helped me along.
totally making a lot more sense now... learning lots from this. PS-glad you listen to your wife and please post more on these topics. Sal rocks.
Thanks for this videos
Thanks for reminding me over and over again that I am paying thousands of dollars to learn these concepts at a higher learning institute... only to find myself looking for you on youtube for the same lessons because nobody teaches it better.
Without these videos on immunity, i could not have taught this topic
