Gut dysbiosis exacerbates inflammatory liver injury induced by environmentally relevant concentrations of nanoplastics via the gut-liver axis

This mouse study found that swallowing nanoplastics at levels found in the environment disrupted gut bacteria and damaged the intestinal barrier, allowing toxins to leak into the bloodstream and cause liver inflammation. When researchers transplanted gut bacteria from nanoplastic-exposed mice into healthy mice, those mice also developed liver damage. This demonstrates that nanoplastics may harm the liver indirectly by first disrupting the gut, a finding relevant to understanding how everyday plastic exposure could affect human health.

Multiomics Reveals Nonphagocytosable Microplastics Induce Colon Inflammatory Injury via Bile Acid-Gut Microbiota Interactions and Barrier Dysfunction

Researchers used multi-omics analysis to understand how large microplastics that cannot be absorbed by intestinal cells still cause colon inflammation in mice. They found that long-term oral exposure to polystyrene microplastics disrupted bile acid metabolism and gut barrier function, leading to the accumulation of specific bile acids that triggered cell death in colon tissue. The study reveals a novel mechanism linking microplastic exposure to intestinal inflammation through bile acid-gut microbiota interactions.

Microplastic-mediated new mechanism of liver damage: From the perspective of the gut-liver axis

This review describes how microplastics can damage the liver through the gut-liver axis: they first disrupt the gut's protective barrier and beneficial bacteria, allowing harmful substances to leak through the weakened intestinal wall into the bloodstream and travel to the liver. Once there, these substances cause inflammation, metabolic problems, and oxidative stress, offering a new explanation for how microplastic exposure could lead to liver disease.

Research progress on the role of gut microbiota dysbiosis in the pathogenesis of immune−mediated liver diseases

This research review shows that an unhealthy gut microbiome (the bacteria living in your intestines) can trigger serious liver diseases where your immune system attacks your own liver. When gut bacteria are out of balance, harmful substances can leak into your bloodstream and cause dangerous inflammation in the liver. The good news is that treatments like probiotics and fecal transplants that restore healthy gut bacteria are showing promise for preventing and treating these liver diseases.

Polyethylene microplastics induced gut microbiota dysbiosis leading to liver injury via the TLR2/NF-κB/NLRP3 pathway in mice

Mice exposed to polyethylene microplastics developed liver damage that was traced back to disrupted gut bacteria -- the microplastics increased harmful bacteria while decreasing beneficial ones, triggering inflammation through the TLR2/NF-kB/NLRP3 immune pathway. This study provides new evidence that microplastics may harm the liver not just through direct contact, but indirectly by first throwing off the balance of gut bacteria.

Single-cell transcriptome analysis of liver immune microenvironment changes induced by microplastics in mice with non-alcoholic fatty liver

Using advanced single-cell analysis, researchers showed that microplastics worsened non-alcoholic fatty liver disease in mice fed a high-fat diet by changing how immune cells behaved in the liver. Microplastic exposure amplified inflammatory responses and altered the communication between different liver cell types. This study is important because it reveals specific immune mechanisms by which microplastics could worsen liver disease, a condition already affecting roughly one in four adults worldwide.

Environmentally Relevant Concentrations of Microplastic Exposure Cause Cholestasis and Bile Acid Metabolism Dysregulation through a Gut-Liver Loop in Mice

Mice exposed to environmentally realistic levels of polystyrene microplastics for 30 days developed damaged intestinal barriers, liver injury, and disrupted bile acid metabolism. The study revealed a gut-liver feedback loop where microplastics alter gut bacteria, which changes bile acid production, which in turn causes further liver damage, suggesting a mechanism by which everyday microplastic exposure could harm digestive health.

Gut Microbiota Participates in Polystyrene Microplastics-Induced Hepatic Injuries by Modulating the Gut–Liver Axis

This mouse study showed that polystyrene microplastics cause liver damage partly through disrupting gut bacteria, which then triggers harmful signals along the gut-liver connection. When researchers eliminated gut bacteria with antibiotics, liver damage from microplastics was reduced, confirming the gut microbiome plays a key role. Green tea extract (EGCG) helped protect the liver by restoring healthy gut bacteria, suggesting diet may help counteract some effects of microplastic exposure.

Chronic exposure to polyethylene terephthalate microplastics induces gut microbiota dysbiosis and disordered hepatic lipid metabolism in mice

Researchers found that mice exposed to PET microplastics (the type commonly found in plastic bottles) over 17 weeks developed liver damage, including fat buildup, oxidative stress, and cell death. The study revealed that the damage was driven by changes in gut bacteria that altered lipid metabolism, and when researchers depleted the gut bacteria, the liver damage was reduced. This suggests the gut microbiome plays a key role in how microplastics cause harm to internal organs.

Impact of microplastics and nanoplastics on liver health: Current understanding and future research directions

This review summarizes what scientists know about how micro- and nanoplastics affect the liver, which is one of the first organs exposed because it processes everything absorbed from the gut. The particles trigger oxidative stress, disrupt energy metabolism, cause cell death, and promote inflammation, and may contribute to conditions like fatty liver disease and liver fibrosis. The paper also highlights how plastics can disturb the gut microbiome, which communicates with the liver through the gut-liver axis and may amplify liver damage.

Multi-omics association pattern between gut microbiota and host metabolism of a filter-feeding fish in situ exposed to microplastics

Scientists exposed filter-feeding fish to environmentally realistic levels of microplastics and found that the particles reshaped gut bacteria communities, which in turn altered the fish's liver metabolism through changes in amino acid processing. This gut-microbiome-to-organ connection matters because it shows microplastics may affect human health not just through direct toxicity but by disrupting the beneficial bacteria in our digestive systems.
