Crosstalk between γδ T cells and the microbiota

Area of Science:

• Immunology
• Microbiology
• Gastroenterology

Background:

• Gamma delta (γδ) T cells are a distinct T cell subset with crucial roles in immunity.
• The gut microbiota significantly impacts host immune system development and function.
• Interactions between γδ T cells and the microbiota are implicated in tissue homeostasis and disease.

Purpose of the Study:

• To review the role of the microbiota in modulating γδ T cell development and function.
• To evaluate the evidence for γδ T cell selection of commensal microbial communities.
• To discuss the implications of microbiota-γδ T cell interactions in health and disease.

Main Methods:

• Literature review and synthesis of existing research.
• Analysis of studies investigating γδ T cell responses to microbial stimuli.
• Evaluation of evidence from mouse and human studies.

Main Results:

• Microbiota influences γδ T cell development and cytokine production, including IL-17.
• Microbiota-derived signals shape γδ T cell populations in various organs.
• γδ T cells play roles in gut-brain axis communication and neuroinflammation.

Conclusions:

• Bidirectional interactions between γδ T cells and the microbiota are critical for immune regulation.
• Understanding these interactions opens new avenues for treating immune-mediated diseases.
• Further research is essential to elucidate the complexities of microbiota-γδ T cell crosstalk.
