Mechanism of B-Lymphocytes

[@joseluisramirezaparco8102]

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 :-)

[@shariqmajeed8709]

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

[@alexandrasss11]

So sad this video has only 5.7k views..I bet a lot of people would watch it if they knew about this channel

[@raymurderd5031]

almost 70k now

@ 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!

U0⁰i nie ma co do jej

[@raanoooshh9296]

5:25 for clear picture! I cannot thank you enough for these videos!!! :D

[@pegahvatankhah238]

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 KZbin or google just to watch your's. thanks a lot

[@littlewitch95]

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

[@gabypinzon256]

this is amazing!! you are my hero.

[@kalivaraprasad9320]

thank you so much doctor..your videos are helping me a lot..

[@chikitawitaa]

Literally the best explanations of every topic

[@AbdulAli-ku9he]

agree

[@eceyucel4444]

this channel is not appreciated enough....

[@alexandregouveia656]

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

[@valeaves]

Alexandre Gouveia You can just increase the speed. I watch it at 1.5x speed 🤷🏼‍♀️

[@yenn5671]

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

[@isabelleval9585]

AMAZING EXPLANATION! thank you so much!

[@jafarloobia3376]

Good and thanks for demystifying a complex issue. If u add animations it is perfect

[@Farfall4Anonim4]

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?

[@davidloop9243]

+ila93ria i guess somatic recombination is amazing

[@dufo4766]

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

[@armoda1057]

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

[@الاحياءمعدكتورمحمدبهاء]

great video, thank you man

[@Esther_ola]

Thank you sooo muchhhh this video was really helpful.

[@xamsexayd2851]

Thank you very much

[@gt4941]

our bodies are genius

[@mahrukhnaqvi1329]

you are incredible

[@hermosadios308]

100 out of 100 too good u made a complex one into simple thnkx

[@hermosadios308]

Subscribed now after watching dis

[@gabyfridman7475]

Thank you !!!

[@satishdarlz7655]

Really excellent video among the immunology videos I have watched before thank u sir

[@chavviattri7204]

Thank you sir so much for clear our basic topics

[@noam8819]

I have nothing more to say than thank you!

[@meeromeer8812]

Thanks.

[@cavelinguam6444]

You are the best

[@rahafsay5708]

Thanks man you save me before every exam

[@elishamapetion8427]

thank you! so understandable

[@thenaturalnubian5430]

Excellent!!!!

[@MrEphratah]

Very helpful and easy to understand. Thank you very much!

[@dr.allwyndsouza5246]

Excellent lecture sir. Always love your videos.

[@marshad.2257]

Excellent explanation! Thanks so much!

[@sujabenadict8757]

Really awesome lecture.....

[@guy_vs_girl]

sir u said that digestive enzymes breaks down antigens in 3rd step so how u bind that antigens to that protein in 5th step ?

[@victoracosta1104]

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. :)

[@chimudzumiti8142]

You're the best bro 💕

[@mauicelta4019]

better than lecture in university!!!

[@wessamaldallal1361]

BEAST VIDEO!

[@Paul-ww5ht]

totally awesome lectures

[@mahimameshram3101]

I am thankful to God .....that I found this channel....which is going to be very Helpful for me for my physiology
