CD274 and type 1 diabetes mellitus: The sub-congenic strain Idd9.2 showed a reduced cumulative incidence of diabetes at 56% (between days 4–18), whereas the Idd9.1 and Idd9.3 strains had a much higher cumulative incidence with 95% and 90% respectively (onset from day 3 to day 22), which is quite similar to 93% type 1 diabetes in anti PDL1 treated NOD mice (between days 4–12) (Figure 1b, Table 1, 2).
