In silico analysis reveals interrelation of enriched pathways and genes in type 1 diabetes

Area of Science:

• Immunology
• Genetics
• Bioinformatics

Background:

• Type 1 diabetes (T1D) is a complex autoimmune disease affecting pancreatic beta cells.
• Previous genetic studies often focused on individual genes or single nucleotide polymorphisms (SNPs).

Purpose of the Study:

• To collectively analyze documented T1D-associated genes using bioinformatics.
• To identify common genes, pathways, and interrelationships between T1D-associated genes and T1D-related genes from SNPs.

Main Methods:

• Bioinformatic analysis of T1D-associated genes.
• Meta-analyses of T1D-associated genes and T1D-related genes from SNPs.
• Enrichment analysis, network analysis, and interactome analysis.

Main Results:

• Identified enriched pathways including cytokine signaling, immune response activation, and Th17 cell differentiation.
• Interactome analysis showed an overrepresentation of T1D-associated genes.
• Highlighted pathways related to vitamin D metabolism, interleukins, toll-like receptors, and antigen processing.

Conclusions:

• Immune system pathways play a critical role in the etiology, metabolism, and progression of T1D.
• Approximately 153 genes within identified pathways are crucial for T1D.
• These findings may inform the development of precision medicine therapeutics for T1D.
