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

[@errordude16]

You Sir, are a legend!

[@LegeFles]

Abominatrix650 very nice

[@StarsingerOG]

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

[@StarsingerOG]

proliferation of B-cells to be specific

[@MEMO2011O]

I love you

[@Heavensdoor92]

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?

[@DrHazi]

what do u do?now

[@Zeydhan]

You seem really proud of your wife :)

[@HearttStringss]

I learn more from these videos than my university classes….

¡Im Mexican and I find this offensive lol!

[@leonidr8517]

Education is outdated needs to be revised and optimized.

[@bayleewalker2414]

No kidding.

[@bodhach]

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.

[@MsAudesapere]

nice clarification, my pathology book actually just lumps together suppressor/cytotoxic T cells

[@148Ashleigh]

There are also NKT, γδ T cells and memory T cells.

[@emmanuelamadi8982]

Bodh A thanks

[@RamirezHD]

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.

[@kjeshfdskjhfkjdshfkj]

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 😂

[@RiazAhemadpharmacologyliu14]

People says they learn here lucidly than university, there should be a KZbin University.

[@sobster123]

too right!

[@alexandradieffenderfer7789]

I know i already said this but you rock. You saved my life on this test. Thanks dude

[@heatherperry2665]

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!

[@joonkim2601]

I want to thank your hematologist wife for clarifying the term "plasma cells." I was so confused when you kept saying "effector B cells."

[@patiencekalua5650]

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

[@rockangelaol]

Thank you so much I have been fighting with Immunology for 2 days! This certainly cleared some stuff up.

[@thomasfishman3075]

those vids still save life in 2019 ! Thanks

[@izzyizzington6321]

SO GREAT!!! thanks so much! I understand so much better now!

[@nikkisummeybowen6542]

You do an amazing job explaining something that I thought was so complicated! Thank you so much for posting!! Very helpful!!!!

[@Nadine-kw1nx]

your saving my life right now!! thank you

[@jedgooridge3815]

THANK YOU SO MUCH! this really helped to clear up the information in my head

[@stethoscopembrn2658]

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!

[@stephh3654]

I learned more from these videos than I did from sitting in class. Thank you!!!!!

[@andthestars]

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!

[@ktd134]

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!

[@olivianorris7939]

His voice is so familiar, so soothing, so comforting. I love it.

[@animalcracker2011]

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!!!

[@alimirza753]

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.

[@marianapetkova325]

Extraordinary! Thank you!

[@sexijag1]

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!

[@Azadehm123]

Very appreciated. It always helps to tie in the concepts together.

[@MrXcon84]

This is really helpful. not only did it make it easier to understand in a conceptual way, but also in a visual way. Thanks!

[@MsCookieMunchkin]

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!

[@ellenffoulkes5415]

This was so helpful! Thanks!

[@erinolaaraoye751]

Thank You so much for making these videos. Im learning a lot so fast! God Bless you!!

[@Durancrazy]

are you kidding? this guy nails it. I can finally understand this stuff

[@aprylskahill3738]

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 :)

[@1BrianBrown]

Great video!! Thanks a million Sal!

[@emineaydogdu7097]

Thank you for clearing up everything :)

[@lalazen2683]

you're such a good teacher Sal!

[@may1412]

thank you so much. This is amazing!! You've saved my life from the examination.

[@davidbryan6484]

Great video, its really helpful how you use all the different names of the cells to cater for the different curriculums around the world.

[@lesegomateme5110]

Thank you so much, this was extremely helpful.

[@AA-kz8yd]

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 !

[@samanthaw122]

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

[@lushgreendesert3523]

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.

[@Brently]

Extremely helpful. Thank you so much.

[@Rose0fire]

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!

[@kendranieuwendorp5511]

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.

[@vg473]

This video is very helpful thank you so much !

[@parvathymohan5490]

This helped me a lot! Thank you so much...expecting much more from you...! All the best👍🏻

[@itsmehanis]

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 KZbin compared to listening back to podcast provided by the university. This video helps me a lot in consolidating my understanding about immunology.

[@AsIAm3991]

You are the truth!!!!! Thank you sooo much for this. Really!

[@dalilugubre]

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 !!!

[@Luthress]

Very helpful. The clear explanations you give are easy to understand.

[@mcse404]

Great lecture, really helped me to remember the stuff I learned in school. Just wondering, but didn't you forget to mention the Treg-cells (suppressor T-cells)? Don't get me wrong, just had something in mind about them.

[@ebonyharvey639]

Pre-Pharmacy and taking Microbiology. This is very helpful 🙌🏾

[@eater1526]

Thanks for this videos
