Area of Science:

  • Immunology
  • Endocrinology
  • Genetics

Background:

  • Type 1 diabetes involves autoimmune destruction of pancreatic beta-cells.
  • Etiology is complex, potentially involving multiple factors initiating a common pathogenic pathway.
  • Significant gaps exist in understanding genetic susceptibility and islet autoimmunity preceding clinical onset.

Purpose of the Study:

  • Investigate the role of gestational infections and viral factors in Type 1 diabetes etiology.
  • Enhance understanding of genetic risk factors, including HLA and autoantigen processing.
  • Improve identification and therapeutic strategies for individuals at various stages of Type 1 diabetes.

Main Methods:

  • Genome-wide scans to identify genetic risk regions.
  • Analysis of autoantigens and development of standardized autoantibody assays.
  • Study of environmental factors interacting with susceptibility genes.

Main Results:

  • HLA identified as a major genetic risk factor.
  • Autoantibody assays demonstrate high diagnostic sensitivity, specificity, and predictive value.
  • Identification of individuals with slowly progressive Type 1 diabetes (SPIDDM, LADA) enables novel therapeutic approaches.

Conclusions:

  • Understanding the interplay between environmental factors and genetic susceptibility is crucial for developing prevention and cure strategies for Type 1 diabetes.
  • While immune modulation prevents diabetes in animal models, human translation remains a challenge.
  • Further research is needed to combine genetic risk factors with autoantibody markers for comprehensive risk assessment.
