Area of Science:

  • Immunology
  • Endocrinology
  • Genetics

Background:

  • Autoimmune thyroid disease serves as a model for organ-specific autoimmune disorders.
  • Disease development involves a complex interplay of genetic, environmental, and endogenous factors.
  • Current understanding implicates HLA complex and CTLA-4 genes as key genetic predispositions.

Purpose of the Study:

  • To elucidate predisposing factors and disease progression mechanisms in autoimmune thyroid disease.
  • To investigate the interaction between thyroid antigens and the immune system (T cells and antibodies).
  • To explore novel diagnostic and therapeutic targets through advanced molecular techniques.

Main Methods:

  • Analysis of genetic factors, including HLA complex and CTLA-4.

  • Evaluation of environmental influences such as smoking, stress, and iodine intake.
  • Utilizing phage display libraries to identify autoantibody diversity and autoantigenic epitopes.
  • Main Results:

    • Thyroid cells actively participate in disease progression by expressing immunologically active molecules.
    • Phage display libraries enable detailed mapping of autoantigenic epitopes.
    • Identification of TSH receptor antibodies' role in Graves' disease and novel orbital autoantigens.

    Conclusions:

    • A comprehensive understanding of autoimmune thyroid disease necessitates integrating genetic, environmental, and cellular insights.
    • Advanced techniques are crucial for dissecting autoantibody-antigen interactions and identifying new therapeutic targets.
    • Further research into predisposing genes and environmental factors will refine treatment strategies.
