Okay, I've learned a bit lately about T1 and T2 cells, but am looking for more information.  If you know anything about them, can you please share?  Thanks!

Don't know if you know any of the basic background, but hopefully these links will help:
www.daviddarling.info/encyclopedia/T/thymus_gland.html

www.wisegeek.com/what-is-a-t-cell.htm

And an interesting hint of why we might all have such a high incidence of other auto-immune disorders here on the CD forum:

grande.nal.usda.gov/ibids/index.php?mode2=detail&origin=ibids_references&therow=476961

Once you go at all past the basics in immunology, you need to know a lot of jargon otherwise what you find online in particular is just gobbledygook, and finding specific information in particular is like looking for a needle in a haystack.
For example, I could not even find mention of the fact that it used to be thought that there were only 2 classes of T cells, one of which fought off infections and one of which reacted to allergens; the future ratio was decided by exposure to bacteria etc in infancy. Hence (the theory went) in the Western world there was an increasing incidence of allergies because infant hygiene was so much better that young children were not exposed to so many pathogens and there was a skewed ratio of T1 to T2 cells.
Unfortunately it turns out that there are (at least shocked ) 3 types of T cells, which really upsets the applecart - and to complicate matters further, the thymus also harbours B Lymphocytes.
eyes As usual, science gives a great example of how telling only part of the truth can make a lie of the truth.
If you do want to get into the nitty gritty, try using the medical dictionary here:

www.thefreedictionary.com/

If I was in your shoes and really keen to learn, I would either buy a college grade textbook on immunology or cytology (you will find them second hand easily enough) or buy a subscription to a scientific journal like Science, Scientific American or New Scientist - the latter will give you free access to the online archive dating back years, and being weekly will give you quite a lot of pertinent information for relatively little effort.
Hope this helps ! smilewinkgrin
