Innate Lymphoid Cells and Celiac Disease: Current Perspective.

Area of Science:

• Immunology
• Gastroenterology

Background:

• Celiac disease (CD) is an autoimmune disorder triggered by gluten in susceptible individuals.
• While adaptive immunity in CD is understood, innate immune responses, particularly innate lymphoid cells (ILCs), remain poorly characterized.
• ILCs are crucial for tissue homeostasis and immunity, but their specific role in CD initiation and progression is unclear.

Purpose of the Study:

• To review the current understanding of innate lymphoid cells (ILCs) in the gastrointestinal tract.
• To discuss recent findings on ILC alterations in celiac disease (CD) and refractory CD.
• To identify knowledge gaps and suggest future research directions for ILCs in CD.

Main Methods:

• Literature review of recent investigations on ILCs in inflammatory intestinal diseases.
• Analysis of pathophysiological aspects of ILCs in the gastrointestinal tract.
• Synthesis of current knowledge regarding ILC alterations in celiac disease.

Main Results:

• Information on ILC diversity and function has expanded significantly.
• Proposed roles for ILC subsets in inflammatory intestinal diseases exist.
• The specific contribution of ILCs to celiac disease pathogenesis is still limited.

Conclusions:

• Further research is needed to elucidate the precise roles of ILCs in celiac disease.
• Understanding ILCs in CD and refractory CD is crucial for developing new therapeutic strategies.
• Characterizing ILC alterations may provide insights into disease mechanisms and progression.
