Helper T produces IL1 and 2?

Members don't see this ad.

barrons ap has a diagram of the helper-t secreting IL 2 and cytokines which stimulates Tc and B cells ( they ignore Th1 and Th2 differences) and that IL2 being an autocrine as well and yadda yadda, --they initially have the Th being activated by a macrophage with IL-1 and MHC2 binding.

The next page says it is a positive feedback loop that the Th secretes IL-1 which enhances it's activities further. so does it make both?

Oddly enough, Campbell's does not even mention interleukins, only referring broadly to cytokines, so I would stick to just thinking broadly of cytokines (though of course you have some more specifics locked away just in case, the DAT isn't based on Barron's).

Just some random tidbits I gleaned from Campbell's in this area that you might find useful. In the primary immune response, dendrites are the most usual and of most particular importance as antigen presenting cells for the primary immune response. While for the secondary response macrophages are the key, and for the humoral response it's B cells. Obviously when I mention these different APCs I'm talking about the cells that are interacting with the helper T cells.

way to in depth will not need to know that for the test

yeah this might be a little to advanced for the DAT but hey you never know try to find the topics online just for your own clarification i don't want to give you wrong information about this topic but i will be glad to see what others have to say good luck with ur studying!

i have a hard time memorizing something unless i really understand it, but from what i've found macrophage-IL1->Th1/2 .

you do NOT need to know this for the DAT.
im taking immunology now and i honestly thought u were trying to get help for ur immuno class or something.....
way too detailed for the DAT. ur stressin urself for no reason, not worth it

+1 molar3. There are many many classes and subclasses of cytokines produced by T cells with overlapping / enhancing / antagonizing functions. You would be best served memorizing and understanding the broad strokes of immune system and saving your sanity for when you have to take immuno (pain in the ass btw).
