Gut microbiome in type 1 diabetes: A comprehensive review

Area of Science:

• Immunology
• Microbiology
• Endocrinology

Background:

• Type 1 diabetes (T1D) is an autoimmune disease involving pancreatic islet β cell destruction.
• Genetic factors contribute to T1D, but cannot fully explain its rising global incidence.
• Environmental factors, particularly the gut microbiome, are increasingly implicated in T1D pathogenesis.

Purpose of the Study:

• To review current etiological and mechanistic studies on the gut microbiome's role in T1D.
• To highlight the gut microbiome as a central factor in T1D development.
• To explore the potential of microbiome-based insights for T1D prognosis and therapy.

Main Methods:

• Review of existing literature on T1D and gut microbiome research.
• Analysis of etiological studies in human subjects and animal models.
• Examination of mechanistic pathways linking gut microbiome alterations to T1D.

Main Results:

• Growing evidence implicates the gut microbiome in T1D pathogenesis.
• The gut microbiome acts as a key mediator of environmental influences in T1D.
• Specific microbial compositions and functions are associated with T1D risk and progression.

Conclusions:

• The gut microbiome is a critical factor in type 1 diabetes etiology.
• Further research into gut microbiome mechanisms can lead to novel diagnostic and therapeutic strategies for T1D.
• Targeting the gut microbiome holds promise for managing and preventing type 1 diabetes.
