ClearOxidative stress-activated Nrf2 remitted polystyrene nanoplastic-induced mitochondrial damage and inflammatory response in HepG2 cells
Researchers discovered that polystyrene nanoplastics damage human liver cells by causing oxidative stress and mitochondrial damage, but the cells activate a protective pathway called Nrf2 to fight back. When the Nrf2 defense was blocked, the damage from nanoplastics became significantly worse, confirming its protective role. This study helps explain how the liver tries to defend itself against nanoplastic toxicity, and suggests that people with weaker antioxidant defenses may be more vulnerable to liver damage from plastic exposure.

The study suggests that natural compounds may help counteract some of the harmful effects microplastics have on liver health.
Attenuative effects of tamarixetin against polystyrene microplastics‐induced hepatotoxicity in rats by regulation of Nrf‐2/Keap‐1 pathway
Researchers investigated whether tamarixetin, a naturally occurring flavonoid, could reduce liver damage caused by polystyrene microplastic exposure in rats. The study found that tamarixetin helped protect against microplastic-induced liver toxicity by activating antioxidant defense pathways, suggesting potential protective effects of certain plant-derived compounds against microplastic-related oxidative stress.

The results suggest that natural antioxidants may help counteract some biochemical effects of environmental chemical exposures.
Molecular Mechanisms of Phthalate-Induced Hepatic Injury and Amelioration by Plant-Based Principles
This review examines how phthalates, chemicals commonly added to plastics to make them flexible, damage the liver through oxidative stress, inflammation, and disruption of normal cell signaling. People are exposed to phthalates through air, water, food, and skin contact, and the liver bears the greatest burden as the primary organ for processing these chemicals. The findings are directly relevant to microplastics because phthalates can leach from plastic particles inside the body, making microplastic exposure a potential delivery route for these liver-damaging chemicals.
Attenuative effects of poncirin against polyethylene microplastics-prompted hepatotoxicity in rats
Researchers tested whether poncirin, a natural plant compound, could protect rat livers from damage caused by polyethylene microplastics.

The study suggests that natural compounds like poncirin may help counteract some of the harmful effects of microplastic exposure on the liver.
Polystyrene nanoplastics exacerbated Pb-induced liver toxicity in mice
Researchers found that polystyrene nanoplastics exacerbated lead-induced liver toxicity in mice, with co-exposure causing higher lead accumulation, more severe inflammation, increased oxidative stress, and greater disruption of protective Nrf2 signaling pathways compared to lead alone.
Protective effects of herbacetin against polystyrene microplastics-instigated liver damage in rats
Researchers investigated the protective effects of herbacetin, a natural flavonoid, against liver damage caused by polystyrene microplastic exposure in rats.

Sinensetin mitigates polystyrene nanoplastics induced hepatotoxicity in albino rats: A biochemical and histopathological study
Exposure to polystyrene nanoplastics caused significant liver damage in rats, including oxidative stress, inflammation, and cell death, along with elevated liver enzymes that are markers of liver injury in clinical settings. Treatment with sinensetin — a natural plant flavonoid — substantially reversed these effects, restoring antioxidant enzyme activity and reducing inflammatory markers. The findings establish a potential protective role for natural compounds against nanoplastic-induced organ toxicity and illuminate the mechanisms by which nanoplastics harm the liver.

Mitigative potential of kaempferide against polyethylene microplastics induced testicular damage by activating Nrf-2/Keap-1 pathway
Researchers tested whether kaempferide, a natural plant compound with antioxidant properties, could protect against testicular damage caused by polyethylene microplastics in rats. They found that the microplastics triggered significant oxidative stress and tissue damage in the testes, but kaempferide treatment substantially reduced these harmful effects by activating a key protective cellular pathway. The study suggests that natural antioxidant compounds may help counteract some of the reproductive harm associated with microplastic exposure.
Evaluation of polyethylene microplastics toxicity using Nrf2/ARE and MAPK/Nrf2 signaling pathways
Researchers exposed male and female rats to varying doses of polyethylene microplastics and found dose-dependent increases in oxidative stress markers and disruptions to reproductive hormone levels. They identified specific cellular signaling pathways, including the Nrf2 antioxidant response system, that were affected by microplastic exposure. The study suggests that microplastic ingestion may trigger oxidative damage and reproductive effects through identifiable molecular mechanisms.

While focused on intestinal health generally, the mechanisms studied are relevant to how microplastic exposure can damage gut barriers.
Nanoplastics and Microplastics May Be Damaging Our Livers
This systematic review summarizes research on how micro- and nanoplastics may damage the liver. Since the liver is the body's main detoxification organ, it plays a key role in processing plastic particles that enter the body through food, water, and air, and the evidence suggests these particles can cause inflammation, oxidative stress, and other liver problems.
Adverse effects of pristine and aged polystyrene microplastics in mice and their Nrf2-mediated defense mechanisms with tissue specificity
Researchers exposed mice to pristine and UV-aged polystyrene microplastics via intratracheal instillation and found structural damage to the gut, liver, spleen, and testis.
