Defensive remodeling of gut microbiota under microplastic stress and its pathogenic mechanism
AI summary Read the abstract
This review pulls together existing animal research on how tiny plastic particles called microplastics—found in food, water, and air—can throw off the balance of good and bad bacteria living in our gut. This imbalance may weaken the gut's protective barrier, trigger inflammation, and mess with metabolism, which over time could contribute to disease. While the gut microbiota does have some natural defenses against this stress, the findings are a reminder that everyday plastic exposure may have hidden effects on our internal health, not just the environment.
Owing to their low cost and durability, microplastics (MPs) are widely used in daily life. However, with their massive emissions, environmental pollution has become increasingly severe. MPs can enter organisms via inhalation, gastrointestinal ingestion, and dermal contact, accumulate in higher trophic-level organisms through the food chain, impair intestinal barrier function, disrupt immune regulation, and alter the structure of the gut microbiota, thereby causing significant harm to the host. The gut microbiota is intrinsically linked to host health and serves as a crucial indicator for toxicity assessment. Therefore, understanding the response of gut microbiota to microplastic exposure is of paramount importance. This review comprehensively examines the impacts of MPs on the gut microbiota across animal models-a subject of widespread global concern. It elaborates on the significance of the gut microbiota and the cascade reactions triggered by microplastic exposure, including metabolic disorders, oxidative stress, and dysbiosis. Subsequently, it discusses the protective mechanisms of the gut microbiota against microplastic stress and the current state of research in this field, both domestically and internationally. Finally, prospects and recommendations for future research on MPs and gut microbiota are proposed. This review provides theoretical support for investigating the relationship between microplastic-induced alterations in gut microbiota and disease pathogenesis, as well as for developing therapeutic strategies. It also provides insights into the underlying mechanisms of interaction between gut microbiota and MPs.

The Gut Microbiome in Foodborne Microplastic Toxicity: Mechanistic Insights and Human Health Risk Assessment
AI summary Read the abstract
This review pulls together existing research on how microplastics we eat, tiny plastic particles found in food and water, may disrupt the trillions of bacteria living in our gut, weakening the gut's protective barrier and triggering inflammation and stress throughout the body. It also points out that plastics can act like tiny rafts, carrying other harmful chemicals into our system and making the damage worse. While scientists don't yet have the full picture, this matters because it suggests the microplastics in our daily diet could be quietly affecting digestive and overall health, making this an area worth watching closely.
Microplastics disrupt intestinal physiology: From microbiota composition to intestinal barrier integrity
AI summary Read the abstract
This review pulls together existing research on how the tiny plastic particles we swallow through food and water may mess with our gut health. The evidence suggests microplastics can shift our gut bacteria toward less beneficial types while reducing helpful bacteria that support digestion, and this may weaken the gut's protective lining—potentially allowing harmful substances to pass into the body more easily. While more research is needed to fully understand the risks, this adds to growing concerns about how everyday plastic exposure might affect our long-term health.
Micro- and Nanoplastics as Environmental Stressors: Mechanistic Links Among Gut Dysbiosis, Inflammation, and Systemic Health Effects
AI summary Read the abstract
This review pulls together existing research on how the tiny plastic particles we're constantly exposed to (in food, water, and air) might harm our health, not just by directly damaging cells, but by disrupting our gut bacteria and triggering chronic inflammation throughout the body. Scientists think this chain reaction could play a role in heart, liver, kidney, lung, and even brain diseases, though the evidence in humans is still early and more research is needed to confirm how serious the risk really is. The takeaway: microplastics may affect health through your gut, not just wherever they physically end up in the body.
Microplastic Toxicity and Intestinal Homeostasis: Insights from Microbiome and Gut Barrier Dysfunction
AI summary Read the abstract
This review pulls together animal, lab, and human studies suggesting that microplastics we eat, drink, and breathe can disrupt the balance of good and bad bacteria in our gut, weaken the gut's protective lining, and trigger inflammation—effects that may ripple out to metabolism, hormones, and even brain function. While most of this evidence comes from animal and lab studies using higher doses than humans typically encounter, it's an early warning sign that everyday plastic exposure could quietly affect long-term gut health, and researchers say we need bigger, more consistent human studies to know how worried to be.
Gut Microbiome Perturbation and Nutritional Outcomes Under Nanoplastic Exposure
AI summary Read the abstract
This review pulls together existing research on how tiny plastic particles (nanoplastics)—along with things like antibiotics and diet—can disrupt the trillions of bacteria living in your gut, potentially weakening your gut's protective barrier, messing with nutrient absorption, and triggering inflammation. Since a healthy gut microbiome is tied to everything from immunity to metabolism, this matters because it suggests plastic pollution exposure could be quietly affecting how well your body processes nutrients and manages inflammation. The authors also discuss potential fixes, like probiotics and gut bacteria transplants, as ways
