Mice were injected i.v. with control IgG or CD25 mAb (PC61) to deplete CD25+ Tregs prior to immunization.
Mice were immunized with mTg or hTg and thyroiditis was assessed on day 28.
Deficient in Ab molecule due to knockout of Aβ chain.
Non-obese diabetic (NOD) background strain deficient in Ab molecule due to knockout of Aβ chain.
