This is an outstanding introduction to and overview of the subject. None of this information existed when I entered medical school 58 years ago! Video clips like these are transforming education, and notably medical education. I am a great fan of the Khan Academy, but your talk is much better that theirs (MHO, obviously).

Thanks for information. Just wondering, if the original antigen presenting cell e.g. macrophage has ingested a bacteria and presents this bacterial antigen to activate a helper T cell, which then combines with an similarly bacterial presenting B lymphocyte leading to the eventual production of B lymphocytes and cytotoxic T cell, how would this cytotoxic T cell that binds to antigens on a MCH class 1 infected cells eg. from a virus, have acquired the specificity for a virus?

It's so nice to finally find someone who explains difficult subjects the way I understand them! But I'm just a bit puzzled about the APC (in this case a macrophage), but at my university they say the Dendritic Cells (DCs) present the proteins and mediate between the helper T-cells and the Cytotoxic T-cells. Can I just 'replace' Macrophage with Dendritic Cells, or is that a whole other story?
@TheXrader123

Dendritic cells found in the tissues of the skin, lungs and GI tract. Interchangeable in examples but I'd like to think it is question dependant.

because b cell already engulf the same pathogen . and those pathogen already break down into peptide and it then display on mhc class 2 on its surface.

I have a doubt - I understood the part where the macrophage breaks the bacteria and removes the antigen from the bacteria onto its surface, but where does the b-lymphocyte get its antigen from - when did it interact with the pathogen?
@enochbrown8178

Neutrophils release their antigens into the tissues. From there, the antigens migrate to the lymph nodes where they meet the B-cell with the correct B-cell receptor.

I thought we learn in class that dendritic cells are the innate immune cells that bridge the adaptive in which they present MHCII with antigen to T cells? This is why I was confused as to why there are 2 other APCs when we get told in class dendritic cells are the cells that travel to lymph to activate T cells

@5omethingsBetterThanNothing
6 жыл бұрын
i am not sure if this is what you mean but yes according to my knowledge as soon as the t-cell is activated it can divide multiply and differentiate into different cells, including cytotoxic t-cell the t cell once activated can divide to form different t-cells including more helper t-cells that release ILK-2 to stimulate other t-cells and ILK-4 which stimulate the proliferation of other b-cell. some also become memory t-cells some also become suppresser t-cells. also cytotoxic t-cells.
