Reduced display of conformational epitopes in the N-terminal truncated GAD65 isoform : relevance for people with stiff person syndrome or DQ8/8-positive Type 1 diabetes mellitus
Aims: To investigate whether the N-terminal truncated glutamic acid decarboxylase 65 (GAD65) isoform is as well recognized by people with stiff person syndrome as it is by people with Type 1 diabetes, and whether conformational GAD65 antibody epitopes are displayed properly by the isoform. Methods: GAD65 antibody-positive healthy individuals (n=13), people with stiff-person syndrome (n=15) and chi
