Sorry for the blank postings, I'm still getting used to this system.
I'm not trying to imply that all of tolerance can be attributed to
cytokines. I agree that clonal deletion is well documented, as well as
the phenomenon of peripheral tolerance. Throw on top of that active
suppression, the requirement for co-stimulation, and you come up
with the murky model for tolerance that I teach the graduate students.
As Ron Schwartz said at a recent Asilomar meeting, "We're missing
something folks". Come on, lets have some new ideas.
By the way, I haven't seen any explanations for the TGFbeta knockout
data. One person indicated that it was a "transgenic artifact".
What do you mean??
