Gut microbiota and immune modulation: role in neurodegenerative disorders and cancer.
Dogra KA, Sharma M, Ghosh N, Kaur G, Singh J
Gut Microbiome
The fermented foods and fiber-rich vegetables you grow or forage feed the same gut microbial communities this research links to brain health — meaning your compost-grown kale and lacto-fermented pickles are doing more than feeding you.
Trillions of microbes live in our digestive tract and constantly talk to our immune system. When that microbial community gets out of balance, it can trigger inflammation that travels through the body and brain, contributing to serious diseases. Scientists are now exploring whether restoring that balance through targeted foods or supplements could help prevent or treat these conditions.
Key Findings
Short-chain fatty acids produced by gut bacteria play a central role in regulating immune responses, maintaining the gut barrier, and reducing systemic inflammation linked to neurodegenerative disease and cancer.
A bidirectional gut-brain communication axis shows differential involvement in Parkinson's disease versus Alzheimer's disease, suggesting disease-specific microbial signatures may exist.
Microbiome-targeted interventions — prebiotics, probiotics, synbiotics, and postbiotics — show translational promise, though human-to-animal study translation remains a key limitation requiring large-scale longitudinal clinical trials.
chevron_right Technical Summary
Researchers reviewed how the community of microbes living in our guts influences the immune system in ways that may drive Alzheimer's, Parkinson's, and cancer — and how dietary interventions like probiotics and prebiotics might one day be used to slow these diseases.
Abstract Preview
The gut microbiota plays a crucial role in maintaining host metabolic balance and immune homeostasis, with increasing evidence linking its dysregulation to neurodegenerative diseases and cancer. Th...

Fermentation is the microbial conversion of carbohydrates into alcohols or organic acids through the metabolic activity of yeasts and bacteria. In plant science, fermentation is central to understanding how plant-derived sugars and starches are transformed during food processing, preservation, and
