The Microbiota-Gut-Brain Axis in Depression: Mechanisms, Microbiota-Targeted Interventions, and Translational...

Area of Science:

• Neuroscience
• Microbiology
• Psychiatry

Background:

• Depression remains a global mental health crisis with limited treatment options.
• The microbiota-gut-brain axis is increasingly recognized for its role in depression.

Purpose of the Study:

• To review the mechanisms of microbiota-gut-brain axis dysfunction in depression.
• To assess novel microbiota-targeted interventions for depression.

Main Methods:

• Literature review of mechanistic studies and clinical trials.
• Analysis of neural, immune, and endocrine pathways.
• Evaluation of emerging therapeutic strategies.

Main Results:

• Microbiota-gut-brain axis dysfunction involves vagus nerve signaling, neuroinflammation, and HPA axis dysregulation.
• Interventions like probiotics, dietary changes, and phage therapy show promise.
• AI-driven personalized medicine offers future therapeutic potential.

Conclusions:

• The gut microbiota represents a promising therapeutic target for depression.
• Restoring microbiota-gut-brain axis homeostasis is key to novel depression treatments.
• Further research can translate mechanistic insights into clinical applications.
