The findings on the immunesystem have been not too consistent, so there is little chance to get anything out of it in a single case. Roughly speaking, in tendency we are in a low inflammation state. If I remember correctly, TGF-beta has been shown most often to be significantly enough elevated, in 63% of the studies. Sorry for not having the reviews at hand, one has been published only recently and is open access (maybe I can manage the next days).
