ClearPalliative effect of taurine against hepatic injury induced by polystyrene microplastics through antioxidant and metabolic pathway modulation in mice
Researchers found that polystyrene microplastics caused liver damage in an animal model through oxidative stress and lipid metabolic disruption, and that taurine supplementation exerted a protective effect by modulating oxidative and metabolic pathways. The results support taurine as a potential therapeutic agent for microplastic-induced hepatotoxicity.
Polystyrene microplastics impact on cardiac and pulmonary physiology and microenvironment in a mouse model: Role of taurine supplementation and molecular docking insights
Researchers investigated the effects of polystyrene microplastics on heart and lung tissues in mice and found that exposure disrupted antioxidant defenses, increased lipid peroxidation, and elevated cardiac injury markers and pro-inflammatory cytokines. Microplastic exposure also upregulated inflammatory and pyroptotic gene expression in both tissues. Co-administration of taurine significantly ameliorated these alterations, suggesting it may offer protective effects against microplastic-induced cardiopulmonary damage.
Hepatic and metabolic outcomes induced by sub-chronic exposure to polystyrene microplastics in mice
Researchers studied the effects of sub-chronic polystyrene microplastic exposure on mouse livers using multiple analytical approaches. They found that microplastics accumulated in liver tissue and caused inflammation, oxidative stress, and disruption of normal metabolic processes including lipid and amino acid metabolism. The study suggests that prolonged microplastic ingestion may pose significant risks to liver health.
PS-MPs Induced Inflammation and Phosphorylation of Inflammatory Signalling Pathways in Liver
Polystyrene microplastics (0.1 µm) induced inflammatory responses and activated multiple inflammatory signalling pathways in mouse and human liver cell lines after 28 days of exposure. The study identified specific phosphorylation cascades through which PS MPs trigger hepatic inflammation, linking microplastic exposure to liver damage mechanisms.
Polystyrene microplastics induce hepatic lipid metabolism and energy disorder by upregulating the NR4A1-AMPK signaling pathway
Researchers found that polystyrene microplastics accumulate in the liver and disrupt fat and energy metabolism by activating a specific molecular pathway called NR4A1-AMPK. This activation triggers a self-cleaning process called autophagy that reduces fat production in liver cells, while also increasing harmful reactive oxygen species. The findings suggest that long-term microplastic exposure could lead to ongoing liver damage through this metabolic disruption.
Impact of the Oral Administration of Polystyrene Microplastics on Hepatic Lipid, Glucose, and Amino Acid Metabolism in C57BL/6Korl and C57BL/6-Lepem1hwl/Korl Mice
Researchers investigated the effects of orally administered polystyrene microplastics on liver metabolism in normal and obese mice over eight weeks. They found that microplastic exposure altered lipid, glucose, and amino acid metabolism pathways in the liver and adipose tissues. The study suggests that microplastic ingestion may disrupt hepatic metabolic functions, with potentially different impacts depending on baseline metabolic health status.
Untargeted lipidomics uncover hepatic lipid signatures induced by long-term exposure to polystyrene microplastics in vivo
Researchers exposed rats to polystyrene microplastics over 6 and 12 months and used advanced lipid profiling to assess liver damage. They found that long-term exposure caused liver inflammation, fatty liver changes, and significant alterations in eight key lipid metabolites involved in fat processing. The study provides evidence that chronic microplastic exposure can disrupt liver lipid metabolism, raising concerns about long-term health effects.
Proinflammatory properties and lipid disturbance of polystyrene microplastics in the livers of mice with acute colitis
Researchers studied the effects of polystyrene microplastics on the livers of mice fed a high-fat diet and found that the particles triggered significant inflammatory responses and disrupted lipid metabolism. The microplastics worsened fat accumulation in the liver and activated inflammatory signaling pathways. The findings suggest that microplastic exposure combined with a high-fat diet may amplify liver damage and metabolic disturbances.
Long-term exposure to polystyrene microplastics induces hepatotoxicity by altering lipid signatures in C57BL/6J mice
Researchers exposed mice to tiny polystyrene particles for 16 weeks and found the plastics accumulated in their livers, disrupting fat metabolism and energy production. The microplastics altered lipid profiles and interfered with key enzymes involved in cellular energy cycles. The study suggests that long-term microplastic exposure may contribute to liver damage through metabolic disruption.
Polystyrene microplastics induce hepatotoxicity and disrupt lipid metabolism in the liver organoids
Using lab-grown human liver organoids, researchers showed that polystyrene microplastics caused liver cell damage even at concentrations found in the environment. The microplastics disrupted fat metabolism, increased harmful reactive oxygen species, and triggered inflammation in the liver tissue. This study provides early evidence that microplastic exposure could contribute to liver problems like fatty liver disease in humans.
Subchronic oral exposure to polystyrene microplastics affects hepatic lipid metabolism, inflammation, and oxidative balance in gilthead seabream (Sparus aurata)
Gilthead seabream fed polystyrene microplastics for 21 days developed signs of liver damage including fat buildup, inflammation, and oxidative stress -- changes similar to early-stage fatty liver disease. Since fish liver responds to microplastics in ways comparable to mammalian livers, these findings raise concerns about what chronic microplastic exposure might do to liver health in humans and other animals.
Disruption of hepatic metabolism in Lep KO mice.
Researchers found that polystyrene microplastics administered orally for nine weeks accumulated in liver tissue of leptin-knockout obese mice and induced histopathological liver alterations, including disruption of hepatic lipid, glucose, and amino acid metabolism.
Dietary exposure to polystyrene microplastics exacerbates liver damage in fulminant hepatic failure via ROS production and neutrophil extracellular trap formation
In mice with acute liver failure, prior exposure to polystyrene microplastics made the liver damage significantly worse and increased mortality. The microplastics boosted harmful reactive oxygen species and triggered immune cells to form structures called neutrophil extracellular traps, which amplified inflammation in the liver. This study suggests that people with existing liver conditions could be especially vulnerable to the harmful effects of microplastic exposure.
Hepatotoxic of polystyrene microplastics in aged mice: Focus on the role of gastrointestinal transformation and AMPK/FoxO pathway
This study found that polystyrene microplastics caused liver damage in aged mice, with the particles undergoing chemical changes as they passed through the digestive system that may have made them more harmful. The microplastics disrupted key metabolic pathways in the liver, triggered inflammation, and caused DNA damage through oxidative stress. The findings are especially concerning because older individuals may be more vulnerable to the liver-damaging effects of microplastic exposure.

Polystyrene microplastics exposure aggravates acute liver injury by promoting Kupffer cell pyroptosis
Researchers found that long-term exposure to polystyrene microplastics worsened acute liver injury in mice by triggering a specific type of inflammatory cell death called pyroptosis in liver immune cells. When they blocked this cell death pathway either genetically or with a drug, the damaging effects of the microplastics were significantly reduced. The study suggests that microplastic exposure may make the liver more vulnerable to injury by amplifying inflammatory responses.
