Groups of IFN-γ−/−CD28−/− NOD.H-2h4 mice, 6 wk of age, were given NaI in their water for the indicated time. Mice in lines 1–3 were then maintained on plain water (no NaI) as indicated before thyroids were removed.
Numbers of mice with the indicated TEC H/P severity scores.
Thyroids were removed after 4 wk on NaI water, indicating that disease is not fully developed when mice in lines 1–3 were removed from NaI supplementation.
