Diabetes mellitus type I. The present and the future

Area of Science:

• Immunology
• Endocrinology
• Genetics

Background:

• Insulin-dependent diabetes (Type 1 diabetes) is an organ-specific autoimmune disorder.
• The disease involves the destruction of pancreatic beta cells, primarily mediated by T lymphocytes.
• The immunogenetics of Type 1 diabetes and its association with the Human Leukocyte Antigen (HLA) system are critical areas of study.

Purpose of the Study:

• To review current knowledge on the immunogenetics of insulin-dependent diabetes.
• To examine the relationship between HLA system polymorphism, particularly the HLA-D area, and diabetes.
• To discuss potential therapeutic strategies targeting the autoimmune process in Type 1 diabetes.

Main Methods:

• Literature review of existing research on Type 1 diabetes immunogenetics.
• Analysis of studies focusing on HLA system polymorphism and its association with diabetes.
• Exploration of therapeutic interventions for autoimmune diseases.

Main Results:

• The Human Leukocyte Antigen (HLA) system, especially the HLA-D region, shows significant polymorphism.
• Specific variations within the HLA-D area are strongly associated with the development of insulin-dependent diabetes.
• T lymphocyte-mediated autoimmune destruction of pancreatic beta cells is the key pathological process.

Conclusions:

• The HLA system plays a crucial role in the genetic susceptibility to Type 1 diabetes.
• Understanding HLA-D polymorphism provides insights into the autoimmune mechanisms underlying diabetes.
• Targeting the autoimmune destructive process offers potential therapeutic avenues for managing Type 1 diabetes.
