Development of autoimmune insulitis is prevented in Eα^d but not in Aβ^k NOD transgenic mice

Abstract

Two lines of E alpha d-expressing NOD mice were established by continuously backcrossing [E alpha d B6 transgenic mice x NOD] F1 to parental NOD or directly microinjecting the E alpha d gene into fertilized NOD eggs. Similarly, A beta k-expressing transgenic NOD mice were produced. Subsequent histological examination of pancreatic tissues revealed that autoimmune insulitis was prevented in E alpha d backcross and transgenic mice but not in A beta k transgenic mice.
