immune system

thyroid gland inflammation ( J:78309 )

• 54% of mice develop thyroiditis compared to 100% of mice carrying both transgenes on a Rag2⁺ background

decreased double-positive T cell number ( J:78309 )

• the number of CD4 T cells in the spleen and lymph nodes is severely reduced

• CD4 T cells have a greatly reduced capability to activate and help B cell antibody production in vivo

abnormal T cell activation ( J:78309 )
