It has been reported that different T cell subsets have opposite effects in disease pathogenesis, in particular Th17 and Treg cells.

METHODS Serum, vertebrae and femur bones were collected from eight-month-old polyarthritis SKG mice and controls.(More)
Monoclonal antibodies (mAb) have been shown effective in inducing immune tolerance in a range of animal models of autoimmunity, allergy, and transplantation. We investigated whether CD4-blockade, effective in inducing transplantation tolerance, could prevent systemic immune responses leading to anaphylaxis. We found that treatment with a non-depleting(More)
