Humoral Immune Response Animation

[MikeyIV]

Hi, good video! However, what cytokines do the T helper-cells release to the B cells to activate them? Can someone tell me the name? Thank you.

[Abominatrix650]

This is such a good video! Thank you for uploading it! It could be the very thing I need to complete my Immune System assignment

[ShorinKan]

awesome... i'm pulling an all-nighter and was struggling with this, helped a lot, thanks uploader

isnt the begining about phagocytosis and i thought humoral response is when the B cells contain receptor that can recognise one type of antigen and when binds it activates to cline itself making copies and activation is assisted by the presence of lymphokines secreted by T4 cells. Then memory celss and effector cells are produced and effector are plasma cells which secrete antibodies and phagocyte binds to the y shaoed antibody and digest the bacteria

[AlizzPanpon]

@SluTbiO The phagocytosis is part of the non-specific immune system but it is needed to activate the T helper cells which will later start a cytokinesis of the B cells that do engulf pathogens as well and ultimately producing B effectors and memory.

[werty400]

B-cells do not ingest pathogens as seen in the video, they break off pieces through receptor-mediated endocytosis and then present them with the MHC II proteins, just a word of warning for AP bio studiers...

Thanks.Simple and good.

this video lowered my stress level at the moment...considerably

Amazing video :)

[1ironaut]

a bacteria isn't an antigen.... bacteria are full of antigens which are fragments of proteins or polysacharrides. other than that everything was useful

[AlizzPanpon]

@1ironaut Antigens can simply be carbohydrates, glycoproteins, proteins, toxins produced by bacteria or whole organisms including bacteria and viruses.

very good video.

has helped a lot.

Very, very helpful

[L2WC]

I always thought that the antigens of cells were simply the markers on their membranes and that the cells themselves were the pathogens (If causing harm to the body). Can the cells themselves be considered to be both pathogens and antigens at the same time?

[freemovies411]

@L2WC Well, if the body cells are from someone else, then they would have a different antigen than your own and be considered "foreign" to the body. That's why when you get an organ transplant, there's a possibility the organ will be rejected by the body - because the antigen might read foreign.

Helped a lot. Excellent video.

[Tamarica1987]

it is MHC 1

[Babykangaroo15]

That is not the right structure for class 2 MHC, that is the structure of MHC 1.

[washytown88]

@Babykangaroo15 so what's the difference between humoral and cell mediated immunity? they both use macrophages to initiate the response. is it just that cell mediated doesn't use b cells?

[Babykangaroo15]

@washytown88 You are correct, the cell mediated immunity does not need B-cells to initiate a response. Humoral involves the uptake and presentation of anitgen via antigen presenting cells (macrophages and B-cells). Cell mediated involves non-immune cells themselves processing antigen internally and then displaying it to T-cells. Such examples include virus-infected cells. These cells display the virus antigen on MHC I to the helper T cells, activting cytotoxic T cells to kill the infected cells.

dfffffffffffffffffffffffffffff­f

[khanlife569]

awesum video...helps a lot......XD

[dumonday]

that makes it really clear!

but i dont think it mentioned clone B and T memory cells..

[Piadorra]

this is a great video,

it helped me alot with my a-levels in class

thanks a bunch!

[sofrito34]

awesome video, going to get an A tomorrow!!
