Compared with the BA, the IL-2 levels were decreased in the spleen of fatteners in the BA+APS (p = 0.027), the IFN-γ levels were decreased in the serum of fatteners in the BA+APS (p = 0.046) and the IL-6 levels were also decreased in the serum of fatteners in BA+APS (p = 0.039). Here, IL6 is linked to autoimmune polyendocrinopathy.
