From what I know,those are like some sort of example of the protein complex that binds to the membrane surface of the B cells.Each B cell has 10000 proteins like those on its surface.There are different proteins complexes for each B cell.Those proteins have "receptors" which bind to the pathogen and then they clone themselves and create memory cells and effector cells(they'll become antibodies' factor, which will produce more proteins like the ones who can bind to the pathogen)sorry 4 my English

Hello, first of all, congrats for your research and knowledge. Then: 1)what are the top 3 foods that could trigger a genetic mutation, in my body, that would give me an active, "foxo 3a gene"? 2) some doctors say that taking vitamins in tablets is unuseful, as the body absorbs vitamins only when they come from the original source, ex vitC is absorbed only when eating an orange (or other foods containing vit C). Do you agree with this statement? Gennaro

can someone explain to me what an immunoglobulin is and what it looks like? i though it was something like an antibody and that it attaches to the b cell somehow

zomglolsly commented on 10 Jun 2010

wait so let me get this right.. antibody = from the body antigen = anything you consume/breathe in that is recognised by the body as a threat?

Thank you for the excellent, clear and informative video. Sidenote, sexy voice! Talk some science into me baby!

i want to know what is a dangerous level of ana in the blood 5 or under being normal mine was 17 i was told

@fancyladydiane1 ANA = anti-nuclei antibody, that's all I know

We have already discussed the pathway 1 of humoral immune response. Step wise explanation of B cell-T cell interaction in Humoral Immune Response. In this Humoral Immune response pathway, B cell acts as antigen presenting cells (APCs). Antigen bound B cells activate T helper cells which in turn activates B cells ultimately forming antibodies.

Great video, really succinct and helpful. I just want to confirm that, as the video states, it is the B cell which encounters the allergen and then activates the Th2 and not an APC encounters the allergen which in turn activates the Th2 cells which then activates the B cell and class switching?

Marina Jeffery commented on 07 Feb 2015

This video, and all of your other hypersensitivity videos, helped me sooooo much! I am so grateful that I could finally get it!

How does splicing increase the diversity? I thought the recombination of DNA selects for the particular VDJ segments. So in the end, u get a DNA loci that specifically encodes a type of variable region. This then gets transcribed and the RNA spliced to give the mature mRNA. So overall.. It seems (to me at least) that the DNA recombination does the diversification. But can someone shed some ight on how the splicing contributes to diversification too?

QueefSniffer commented on 14 Mar 2011

Random cool fact: the adaptive immune system that uses V(D)J recombination to create antigen recognition sites, rather than using genetic recombination in the variable lymphocyte receptor gene, were the gnathostomata (jawed vertebrates). Wikipedia baby!
