Interactions between gut microbiota and emerging contaminants exposure: new and profound implications for human health
This review explores how emerging contaminants like microplastics, antibiotics, and persistent organic pollutants interact with gut bacteria and what that means for human health. Researchers found that the gut microbiome is a key target of these pollutants and may play a role in organ damage, hormonal disruption, and other toxic effects through pathways like the gut-liver and gut-brain axes. The study underscores the importance of understanding the three-way relationship between environmental contaminants, gut bacteria, and overall health.
Oxidized/unmodified-polyethylene microplastics neurotoxicity in mice: Perspective from microbiota-gut-brain axis
Mice exposed to both regular and environmentally weathered polyethylene microplastics developed brain and gut damage, including behavioral changes, weakened gut and blood-brain barriers, and inflammation -- with weathered microplastics causing even more harm. Importantly, treatment with a probiotic (Lactobacillus) and a prebiotic partially reversed these effects, suggesting that gut-friendly supplements might help protect against microplastic-related brain and intestinal damage.
The detrimental effects of micro-and nano-plastics on digestive system: An overview of oxidative stress-related adverse outcome pathway
This review maps out how micro and nanoplastics damage the digestive system, identifying oxidative stress as the initial trigger that leads to inflammation, cell death, disrupted gut bacteria, and metabolic disorders. The authors use an adverse outcome pathway framework to connect molecular-level damage to broader health consequences. The findings suggest that ongoing microplastic exposure through food and water could contribute to digestive health problems.
Pollutants, microbiota and immune system: frenemies within the gut
This review summarizes how environmental pollutants, including microplastics, disrupt the gut microbiome and immune system, potentially contributing to inflammatory bowel diseases and colorectal cancer. Pollutants reduce beneficial gut bacteria while promoting inflammation, weakening the intestinal barrier, and triggering a chain of events that can push cells toward cancerous growth.
Natural Compounds in the Modulation of the Intestinal Microbiota: Implications in Human Physiology and Pathology
This review examines how natural compounds including polyphenols, fatty acids, and fiber can modulate the gut microbiome and affect human health. While focused on nutrition and gut health rather than microplastics, the gut microbiome is increasingly recognized as a target of microplastic toxicity, making dietary protective factors relevant.
Gut microbiota as an emerging target for the health implications of microplastics
This review examines how microplastic exposure disrupts the gut microbiome, finding evidence that microplastics damage intestinal barrier proteins, promote inflammation and oxidative stress, and may drive systemic effects including neurotoxicity and reproductive toxicity through gut-mediated pathways.
Microplastics and human health: unveiling the gut microbiome disruption and chronic disease risks
This review summarizes evidence that microplastics disrupt the gut microbiome, the community of bacteria in our digestive system that plays a key role in immunity, metabolism, and overall health. By altering gut bacteria balance and triggering inflammation, microplastic exposure may contribute to chronic conditions including inflammatory bowel disease, metabolic disorders, and potentially even neurological problems through the gut-brain connection.
Anthocyanins as protectors of gut microbiota: mitigating the adverse effects of microplastic-induced disruption
This review examines how anthocyanins, bioactive compounds found in berries and other pigmented plants, may protect gut microbiota from disruption caused by microplastic exposure. Researchers synthesized evidence suggesting that anthocyanins counteract microplastic-induced oxidative stress and inflammation in the gut. The findings indicate that dietary anthocyanins could serve as a protective factor against the adverse effects of microplastics on digestive health.

Probiotics an emerging therapeutic approach towards gut-brain-axis oriented chronic health issues induced by microplastics: A comprehensive review
This review examines how microplastics disrupt the gut-brain axis, the communication system between the digestive system and the brain, leading to chronic health problems like inflammation and neurological issues. The authors highlight probiotics as a promising treatment approach, since beneficial bacteria can help repair gut damage caused by microplastic exposure. The findings suggest that supporting gut health through probiotics may help counteract some of the harmful effects of microplastics on both digestion and brain function.
Mitigating microplastic-induced organ Damage: Mechanistic insights from the microplastic-macrophage axes
This review is the first comprehensive examination of how microplastics interact with macrophages, the immune cells responsible for engulfing and removing foreign particles from the body. When macrophages absorb microplastics, the resulting oxidative stress disrupts their normal function, leading to inflammation and organ damage, with gut bacteria potentially playing a role in this harmful process.
