2.5.1 Sera collection
Sera from diabetic patients (n = 49) were selected among the samples
collected in our laboratory during the routine detection of
autoantibodies (Servicios Tecnológicos de Alto Nivel, STAN-CONICET).
Control sera were obtained from 51 healthy subjects without personal or
family history of autoimmune disease.
This work was performed with the approval of the Ethical Committee of
José de San Martín Clinical Hospital, Buenos Aires, Argentina.
All experiments were done in accordance with the relevant guidelines and
regulations.
Written informed consent was obtained from all participants.
