i just love you for making these videos and helping a huge student community with passing their exams. i am so blessed with your channel. i ignore other video suggestions on RUclips or google just to watch your's. thanks a lot
Thank you so much, i got an A for the essay question parts thanks to your videos, and that i missed a lot lecture and just cram for the exam in 5 days lol
@ AK Lectures Hi, Just wanted to say that I love your videos and they are my saviour right now! It's so much better than reading a textbook! (I have an immunology exam next week! :O ) So thank you!! Also, I might just be being stupid right now but I wanted to clarify, do B cells undergo cell mediated or receptor mediated endocytosis of an antigen? Also how does this differ from macrophages and dendritic cells, I thought that all antigens bind to surface receptors before they are engulfed? Thanks!
In the other you said that T helpers were cloned, but in this video you state that B-Linfocythes are cloned. This is not accurate... I am following all your fascinating videos, please do not disappoint me :-)
Yò Kargwal the antigen was degraded into small peptides, or epitopes, in the 3rd step. This is needed for the presentation in the 5th step because MHC2 can only bind small peptides (13-18 amino acids long). Im guessing the error in the video was using the word Antigen in both cases. Hope that woks. :)
something difficult to understand is: when we meet the t-helper, it has to have the receptor for that specific antigen, but if it's the fist time we meet that particolar antigen, (so primary response) how can this t-helper already have the specific receptor for it?
Both T-cells and B-cells have tremendous potential for random rearrangements of their receptor's variable regions, so they are prepared for everything. In other words, they make specific receptors for pretty much anything they may encounter, not anything they have already encountered! When the antigen comes by the right clones, specific for the right antigen, get selected and multiply. That's the essence of adaptive immune system
the immune system generates billions of different B cells and T cells. chances are one of them will be able to recognize the epitope since T cells only recognize small peptides from the antigen when it is presented in MHC molecules
1k tuition a year and there's noone who can teach me as well as this guy. i've used your videos for everything from chemistry to phisiology to imunnology. if i could make one suggestion is that you play the videos a little faster. if anyone has trouble understanding they can pause the video, and otherwise it takes a lot of time to get through each subject

Out of all RUclips's video this is the most fascinating one

5:25 for clear picture! I cannot thank you enough for these videos!!! :D
You are a life save read this topic in the text book over and over again and didn't get a thing but understood when you explained
this is amazing!! you are my hero.
Thank you so much, i got an A for the essay question parts thanks to your videos, and that i missed a lot lecture and just cram for the exam in 5 days lol
Very helpful and easy to understand. Thank you very much!
Literally the best explanations of every topic
agree

U0⁰i nie ma co do jej
thank you so much doctor..your videos are helping me a lot..
Excellent explanation! Thanks so much!
Excellent lecture sir. Always love your videos.
Really excellent video among the immunology videos I have watched before thank u sir

AMAZING EXPLANATION! thank you so much!
Good and thanks for demystifying a complex issue. If u add animations it is perfect
totally awesome lectures
Great lecture!
Thank you sooo muchhhh this video was really helpful.
Excellent!!!!
great video, thank you man
Thanks man you save me before every exam
You are the best
better than lecture in university!!!
So sad this video has only 5.7k views..I bet a lot of people would watch it if they knew about this channel
almost 70k now
Thank you sir so much for clear our basic topics
I have nothing more to say than thank you!
You're the best bro 💕
thank you! so understandable
Really awesome lecture.....
100 out of 100 too good u made a complex one into simple thnkx
Thank you !!!
BEAST VIDEO!
you are incredible
Thank you very much
Thanks.
sir u said that digestive enzymes breaks down antigens in 3rd step so how u bind that antigens to that protein in 5th step ?
Yò Kargwal the antigen was degraded into small peptides, or epitopes, in the 3rd step. This is needed for the presentation in the 5th step because MHC2 can only bind small peptides (13-18 amino acids long). Im guessing the error in the video was using the word Antigen in both cases.

+ila93ria i guess somatic recombination is amazing

Alexandre Gouveia You can just increase the speed. I watch it at 1.5x speed 🤷🏼♀️
Subscribed now after watching dis
