Immunology - Introduction to Antibodies

[@sahanak92]

One little correction - IgA exists as a dimer only in mucous/secretions. In the blood stream, it is a monomer.

Fab region consists of variant and constant regions not only variant as you mentioned.Great videos but i think that you should put under the videos in a Bar the mistakes and some correction. There are students who has no background and come here to study at first, i think that if you want to help those students they should know the correct facts.

I completely agree. Albeit, 6 years late.

Little correction from a biochemist: Isotopes are different versions of the same chemical element which differ in neutron number. I think here the constant region of an antibody encodes the isoTYPE (or class).

[@Farawayrope096]

I'm actually thinking of becoming a biochemist or a medical scientist and I'm just curious as to what you do I've always been interested in cells and how they work and diseases but I'm only 16 and I'm not 100% sure if it's what I want to do

[@r4serONE]

Lord Ovy IX being curious about these types of fields is great. Keep that up! So, I recently graduated as a PhD in chemistry/biochemistry with specialization in mass spectrometry. I studied a lot disease and toxicity-related changes in proteins, such as acute or chronic liver failure. I was lucky and could work a lot on human samples and did not have to rely on/conduct animal studies (I think that’s more common in biology). In these types of studies you learn a lot about biological processes on the macro level and also (bio-)chemical principles on the micro level. It can be sometimes challenging and hard, but it’s always rewarding. And after the studies you have the chance to either stay in R&D in a company or a certified lab, or search a career in the pharmaceutical/healthcare industry

[@Farawayrope096]

@@r4serONE thanks alot for responding I appreciate. Its just in our school we don't get to actually do alot of physical work it's more just theory and writing and it doesn't really give me an idea of the actual subject. So I appreciate this thanks very much.

[@r4serONE]

Lord Ovy IX no worries. We didn’t get much hands-on experience in school either. My first lab experience was in undergrads.

[@lancejohnson108]

I like your videos for use as overviews for my students and I wish I could draw diagrams this well on our markerboards at school. One question though, at 2:54 you mention and write antibody isotope (with an "o"), but do you actually mean isotype (with a "y")? I'm not familiar with the term antibody isotope except for using antibodies for delivering radioactive isotopes.

Consistent and easy. I'd really want to see a video on the modification of antigens and the formation of autoantibodies.

[@akigreus9424]

Does the body use metals available in its enivorment but not needed in its metabolism in the formation of antibodies?

Thanks so much *MR OBALAR* on KZbin for curing me from Herpes, keep saving lives.❤❤

[@yohanabf242]

Hey, great video man just want to correct something: concerning the structure of the antibody, there's a difference between what we call the "Fab fragment" and the "variable region" (and also between Fc fragment and the "constant region"). Indeed, i learned that: -Fab = the whole light chain + the 2 domains of the heavy chain next to the light chain -whereas Variable region = the 2 domains (1 of the light chain, the other of the heavy chain) that interact with the antigen (at the edge). -Fc = the four domains that don't belong to Fab -Constant region = the 8 domains that don't belong to the variable region Besides that, thank you for your work Armando

[@spideylover4105]

yeah I was just about to correct this

[@zannatul23]

[@tal8871]

try $600,000 per cup

[@jacobblom3430]

Isn't the Fab region the entire light chain plus the variable portion of the heavy chain, whereas the Fv region is the variable portion of the antibody?

[@TheSternSaver]

+Jacob Blom Yes!!! He was incorrect in the video.

Hmm, I thought IgA antibodies only become dimeric upon crossing epithelial barriers, though... since the secretory component linking the two IgA antibodies together is derived from a receptor that mediates transcytosis through epithelia(?)

Could you just do a video about HIV, especially how it crosses the placenta to fetus? That would be wonderful!

[@BoBo-dv5cb]

The virus can be pass on to the fetus through the blood as the fetus absorb nutrient from the mother's blood to survive while it is in the uterus. Virus are small enough to pass through the holes on the walls of capillaries so that it can be transport around the body and absorb by the fetus through placenta, umbilical cord then into the body of the fetus.

Hi man, nice video! Just i want to say (because i am from Greece) that the greek letter "gamma" for G antibodies is "Γ" and not "Υ". Very good job anyway

[@bukusakufarter]

I suppose G refers to lowercase γ, not Y

[@kevinscott9158]

You wrote isotype but you keep saying isotope.

[@djdonald2795]

Actually, he wrote it wrong and said it wrong. I was going to recommend this video to a college student, but that was deal breaker for me. You can't be saying isotope when you mean isotype or class and subclass.

[@anuvette]

how do you draw so good

[@nerdchick85]

In ur video u said tht B cells produce antibodies.Technically, its only the Plasma cells tht produce antibodies.Plasma cells are the effector cell of B cells

[@KasDush]

0:18 he say's "Plasma Cells specifically" :)

[@mygoldentruth]

Actually B cells do produce antibodies (they do not secrete them), plasma cells produce and secrete them. Antibodies are part of B cells membrane: B cells produce one kind of Ig with a specific Fab portion. It would be a disaster if they didn't produce antibodies. Hope I helped! :)

You made a mistake. Constant region is not Fc and Variable region is not Fab. Light chain and 1/2 of a heavy chain next to it is known as Fab fragment and the other half of heavy chain is known as Fc fragment. I hope you understand what I mean to say :)
