If anyone needs a mnemonic here's mine: IgG - (General) - Makes up 75% of antibodies, generally distributed throughout blood. Long term immune response. IgA - (Airways) - antibodies found in mucous, nasal cavities, saliva, lungs etc IgM - (Major) largest antibody and first to respond to antigens. Highly effective against viruses. IgE - (Echoo!) - Allergic reactions IgD - (Differentiate) - Helps B cells get activated to differentiate them into plasma and memory B cells
I cannot count the times you've saved my life with your videos. As soon as I start a new course, the first thing i check is if you have videos up on my particular subject, you never fail to deliver. Love your videos, please never stop!!
I AM ALWAYS AMAZED HOW YOU ARTICULATE YOUR EXPLANATION. YOU ARE WONDERFUL IN DELIVERING SCIENTIFIC CONCEPTS. I AM THE HAPPIEST TO FIND YOUR EXPLANATION ON THE YOU TUBE VIDEO. YOU STILL TAKING THE LEAD.
u r very awesome sir....I'm lucky to having u youtube teacher.........i wish to be a professor like u....thank u so much for ur awesome work for students....
8:30 Cytotoxic T cells should have T cell receptors, not antibodies. It's true that naive Tc can be activated by antigen-presenting cells that are infected (e.g. Dendritic cells), but this has nothing to do with antibodies. However, B cells have antibodies as receptors, a.k.a. BCR.
Just wanted to say thank you for all of your help. Your explanations make so much more sense than a book. Also what the heck is your IQ? You look very young for being able to lecture on so many topics. But I am so glad you do!!!!! THANK YOU!!!
Does an antibody belong on the Cytotoxic-T-Cell there, on the diagram? Isn't that receptor is a generic T-Cell Receptor binding to MHC-I. Thank you for the effort that goes into your presentations, they are world-class.
What you said about the 2nd function of immunoglobulins at around 09:05 : Could there be a mistake in your video? It sounds like you're describing the function of the T-Cell-Receptor, but afaik T-Cell-Receptors aren't really immunoglobulins. Anyway I'm thankful for your video and it helps a lot!
Could you make a video about how immunoglobulins are diverse? Meaning gene recombination with V(D)J segments, P and N nucleotides, and class switching? I think this is a hard antibody concept to grasp and you do an awesome job at teaching!
Thanks for your wonderful videos..u are rrally saving me..struggeling with i guess the worst biochem book (is basis for exam) written ever which makes simple things sooo un-understandable..after watching ur videos this makes sense...!!Cant thank u enough!!!!!
Hi there Andrey! First of all thanks heaps for making this available to us students as they are really really helpful to recap things before examinations haha. But just a thing that I want to suggest. Would you mind standing on the left side when you're discussing the right half side of the board? Because this would make it easier to pause the video and read the material written on there before moving on. Much appreciated! Thank you so much! :D
can u plz help me ...how memory cells have memory?..are the b-cell receptors main reason for the memory bcz now ,still after diffrentiation these receptors on memory cell r specific for that same antigen..so in secondry response they can bind to that sepcific antigen again...am i correct?
I love your channel. You help me a lot. Can you please find a way to pronounce my name in any of your videos like you do with your favourite rapper, 2-chains as in 2:22 :P.
+Meghana Bhushan Immunoglobulin is another name of antibody. Here, 'Immuno' means they are the molecules produced by our immune system; and 'globulin' means globular (spherical/globe like). antibody is made of four different types of globe like proteins , two proteins make light chain, other two make heavy chain. Overall antibody is Y shaped structure. Immunoglobulin is general term, antibody is more specific.
I am asking this inspite of u writing "antibodies, also called immunoglobulins" because I've seen many sources that say both are slightly different. so plz do clarify this to me!.... :)
+Meghana Bhushan Yes! Good job for asking that question because technically they are not the same exact thing! You can think of an immunoglobulin as a more general concept than an antibody. Our body produces five types of immunoglobulins. Some of these can be bound to cell membranes while others are free floating. An antibody is an immunoglobulin that has been generated by a cell such as a plasma cell in response to being exposed to an antigen.
If anyone needs a mnemonic here's mine:
IgG - (General) - Makes up 75% of antibodies, generally distributed throughout blood. Long term immune response.
IgA - (Airways) - antibodies found in mucous, nasal cavities, saliva, lungs etc
IgM - (Major) largest antibody and first to respond to antigens. Highly effective against viruses.
IgE - (Echoo!) - Allergic reactions
IgD - (Differentiate) - Helps B cells get activated to differentiate them into plasma and memory B cells
IgG - passinG through placenta
IgA- teAr, sAliva, mucosAl
IgM- 1st iMMune responder.
connect with J- junction (j)i am = IgA & IgM
What a wonderful mnemonic, Thanks!!! A huge thanks to ak lectures as well for delivering these fantastic lectures!!
@@xpbatmanqx5535 No problem! Glad it helped
Great!!! I love it
You're welcome! Good luck with the exam, you got this!
I cannot count the times you've saved my life with your videos. As soon as I start a new course, the first thing i check is if you have videos up on my particular subject, you never fail to deliver. Love your videos, please never stop!!

Great videos. I'm amazed you get all this information over in a single take with no mistakes👍
thank u for these wonderful videos . ur immunology classes are really helping for my studies
what an explanation ?? you are more than amazing and brilliant
The best teacher ever
You did a great job. I suscribed as soon as I saw this video
Thank you sir. Your explanation is really clean and simple making it easier for me to understand.
u r very awesome sir....I'm lucky to having u youtube teacher.........i wish to be a professor like u....thank u so much for ur awesome work for students....
You are an excellent teacher! Thank you!
U deserve more subscribers 👏
Hi, nice video.
As far as i know, CTLs don't have antibodies that recognize MHC (as was drawn on the board), but rather TCRs.
I was just about to comment that
TCRs recognize MHC complexes, that's the point of them. So Cytotoxic t-cells have TCRs which recognize MHC-I or MHC -II
8:30 Cytotoxic T cells should have T cell receptors, not antibodies.
It's true that naive Tc can be activated by antigen-presenting cells that are infected (e.g. Dendritic cells), but this has nothing to do with antibodies.
However, B cells have antibodies as receptors, a.k.a. BCR.
Just wanted to say thank you for all of your help. Your explanations make so much more sense than a book. Also what the heck is your IQ? You look very young for being able to lecture on so many topics. But I am so glad you do!!!!! THANK YOU!!!

Thank you so much sir, for explanation 🤗🙏
Keep doing ur good work, love n respect all d way frm India 😁❤️
Informations that save lives.
Could you make a video about how immunoglobulins are diverse? Meaning gene recombination with V(D)J segments, P and N nucleotides, and class switching? I think this is a hard antibody concept to grasp and you do an awesome job at teaching!
I love this guy
thank you sir for your effort and your greatful.
Thanks for your wonderful videos..u are rrally saving me..struggeling with i guess the worst biochem book (is basis for exam) written ever which makes simple things sooo un-understandable..after watching ur videos this makes sense...!!Cant thank u enough!!!!!
Well done, thank you for the videos!
Thanks sir .....you the best!!!!!!!!
could u please do the differences between proteins and enzymes?im never clear on this.thank you in advance
Thank you so much 🙏🙏🙏
2:35
The logo of ACM has some sort of resemblance with the morfology of antibodies
Thank you 🙏🙏🙏
thnkewww so much sir.....i preprd..best fr my..seminar.
so nice and energetic,,,thanks a lot,,,
many many thanks
Thank you!
Thank you so much, sir!!
Thanks! and could u make some tutorials about different types of anemias?
Education Revolution!

You are awesome thanks
keep up the good work :)
really perfect
thank you so much
Loves from India
thank you
thanks alot
Just a question: Shouldn't it be a cytotoxic CD8 T lymphocyte binding to the CMH1-antigen complex on a infected cell?
Amazing
Hmmm really informative. Think I may have explained something wrong once. Oh well. I know now.
is function #2 of immunoglobulins part of the complement system??
lifesaver thanksssss
Can I have playlist of this video
Great video , but I thought there will be a detailed explanation about the 5 classes of Immunoglobulins :(
Can u explain the const & variable region in brief ?
Thanks for the video~!^^
ChicklePickle14 you're welcome! love the pikachu :)
can u plz help me ...how memory cells have memory?..are the b-cell receptors main reason for the memory bcz now ,still after diffrentiation these receptors on memory cell r specific for that same antigen..so in secondry response they can bind to that sepcific antigen again...am i correct?
I couldn't open this website please provide me this solution
How is it possible to have Antibody expressed on cytotoxic T cell?
I love your channel. You help me a lot. Can you please find a way to pronounce my name in any of your videos like you do with your favourite rapper, 2-chains as in 2:22 :P.
dude dafuq r u saying...ak is a real teacher...he aint no rapper...
sir could u plz tell me whether immunoglobulin n antibody are synonyms? if not what's the difference?

Why is there not a single video on TH-cam about EXPERIMENT DEMONSTRATION OF ANTIBODIES??😭
Please provide clear notes i need screen shot
More attractive education
0:50 "...for which it was built for...". His doctoring is better than his English. "..for which it was built. ..."
Now he is competing with eminem 🤔😂♥️

Thanks a lot especially for a quick answer.. :)
+AK LECTURES (Andrey K) So it's like all antibodies are immunoglobulin but not all immunoglobulins are antibodies??
precisely!
engsub please! my english skill is not good, i cant hear everything, please please!!!!
