Autoantibody with Cross-Reactivity between Insulin and Ductal Cells May Cause Diabetic Mastopathy: A Case Study
Figure 8
Antibody absorption test with insulin added to the primary serum at 40 ng/mL (a), 4 μg/mL (b), and 40 μg/mL (c). Staining intensity attenuated corresponding to insulin concentration. At 40 ng/mL, positive staining of ductal epithelia remained, while at 4 μg/mL, staining intensity decreased significantly and almost disappeared at 40 μg/mL.
