The Immune Response

[torisangels]

I learn so much with these videos that I don't know what I would do without them. Outstanding! Carry on...

[ibbi1824]

how long does it take for your body to respond to pathogens?

[h5348227]

the dendrite cell is like weeeeeeeeeeeeeeee through the lymph node

[knucklescapricorn31]

Thank you so much! Wish this vid was longer though...

[jordanluver17]

best video, but i dnt get where the killer t cells do?

[brightside786]

nice interesting presentation there..

wow at the things the allmighty God has created within us...beyond amazing !!

@brightside786 lol.

[DezAVL]

thanks.. a little more lables would be better.. all in all it was helpful

[MysticalFlyingMonkey]

Ahh, i seem to now be looking forward to my 6hr 15 min revision on Monday <3

[joeynap860]

great vid

[Stardom2010]

Thank-youuuuuuu

15 mins off my exam lol

@sailtheseaofcheese: remember there are two types of t cells, T-helper (Th) and Cytotoxic "killer" T cells (CTL's). CTL's act to kill infected cells by recognising that it has peptide (which the CTL recognises) on the MHC C1. HOWEVER, Th cells act in many ways e.g.activate class switching and affinity maturation in B-cells and ive read some papers too about how they can also present peptide on MHC molecules to other cells-so T cells do no only attack infected body cells.. they have HEAPS of jobs

This is great, tanks a lot!

[camboyda]

This is beyond awesome

[sailtheseaofcheese]

this stuff is so annoying. Every source says something different. i thought T-cells only attack infected body cells!

[thekewlestone]

@sailtheseaofcheese So true......it totally confuses me too

[AideMedicale]

This is an outstanding video - thank you very much.

[Nongmaisiim]

excellent

[LuRunnerBiology]

amazing video.

I love immunology......

[vanessaleb]

Thank you, very clear explanation.

[Muzicboxtecnotunez]

this is basically the graphic display of an immune response from the T- and B-cells which help produce anti-bodies to kill the invading pathogens.

[gracie8861]

i think B cells become the memory cells not the T cells but maybe double check just in case

[sofrito34]

B cells and T cells become memory cells :)

[bourbonstmc]

Some B cells, helper T's (CD4), and killer/cytotoxic T cells (CD8) become memory cells. All three of these types of lymphocytes yield some memory cells.

[gocolago33]

So basically its:

1) Invading Microbes enters the body

2) Macrophages engulf the microbes and produces antigen maker

3)Helper T-Cells reads antigen shape. Identifies it.

4) B-cells produce antibodies which attach to to the identified microbe

5)Killer T-cells go after the microbe

6)Suppressor T-Cells stops this immune response

7)Memory T-Cells hold imprint of antigen, thus the next time the infection occurs the immune system is ready.

?

[bourbonstmc]

Killer T's (CD8) act at the site upon cells displaying foreign proteins in their MHC complex (cell-mediated). B cells and antibodies comprise the humor-mediated aspect of specific immunity. This vid does a good job of showing how the 2 types of specific immunity can work together. Don't forget that killer T's, helper T's, and B cells all produce their own memory cells.

[MrSymposier]

Very graphical explanation of how does Immune system respond to infections! Besides Vaccines and enteric diseases VED 2009 Congress will cover topics related to parasitology, pathogens and of course, allergie and immunology. For more information visit Symposier site!

you are good!!
