It was revealed that the level of IL-1β, IFNγ and GM-CSF was higher in T1D patients with two or more autoantibodies compared to the patients with single autoantibody or without any (Mann–Whitney U-test; U = 12.36, p = 0.00044 for IL-1β; U = 6.58, p = 0.010 for IFN-γ and U = 6.86, p = 0.0088 for GM-CSF). Here, IFNG is linked to type 1 diabetes mellitus.
