This review details islet autoantibodies, key markers for type 1 diabetes (T1D) autoimmunity. Understanding these autoantibodies and their targets aids in T1D diagnosis, prognosis, and prediction in at-risk individuals.
Area of Science:
- Immunology
- Endocrinology
- Diabetology
Background:
- Islet autoantibodies are primary indicators of pancreatic autoimmunity in type 1 diabetes (T1D).
- These antibodies target specific antigens like insulin (IAA), GAD (GADA), IA-2 (IA-2A), and ZnT8 (ZnT8A) within pancreatic beta cells.
- Liquid phase assays provide sensitive and specific measurement of these critical autoimmune markers.
Purpose of the Study:
- To review current knowledge on autoantigens recognized by islet autoantibodies.
- To summarize the phenotype of islet autoantibodies observed in large prospective studies.
- To highlight the role of islet autoantibodies in understanding the natural history of T1D.
Main Methods:
- Analysis of data from large prospective studies monitoring children at risk for T1D from birth.
- Review of current literature on islet autoantigens and autoantibody phenotypes.
- Utilizing sensitive and specific liquid phase assays for antibody detection.
Main Results:
- Islet autoantibodies (IAA, GADA, IA-2A, ZnT8A) are crucial for T1D diagnostics and prognostics.
- These antibodies are key parameters for monitoring autoimmune responses in T1D patients.
- Longitudinal studies reveal distinct autoantibody phenotypes in individuals developing T1D.
Conclusions:
- Islet autoantibodies are indispensable tools for exploring T1D's natural history.
- Understanding autoantibody profiles aids in predicting T1D onset in at-risk populations.
- This review consolidates knowledge on autoantigens and autoantibody phenotypes for improved T1D management.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
