ClearAdipose tissue as target of environmental toxicants: focus on mitochondrial dysfunction and oxidative inflammation in metabolic dysfunction-associated steatotic liver disease
This review examines how environmental toxicants, including micro and nanoplastics, target fat tissue and contribute to metabolic diseases like obesity, diabetes, and fatty liver disease. These pollutants disrupt mitochondria (the energy-producing parts of cells) and trigger a cycle of oxidative stress and inflammation that damages both fat tissue and the liver. The findings suggest that microplastic exposure could be one of several environmental factors contributing to the rising rates of metabolic disease worldwide.
Microplastics and nanoplastics: Emerging drivers of hepatic pathogenesis and metabolic dysfunction
This review examines emerging evidence linking micro- and nanoplastic exposure to liver disease, including metabolic dysfunction-associated liver disease, cirrhosis, and liver cancer. Researchers found that these particles may contribute to liver damage through oxidative stress, inflammation, and disruption of metabolic pathways. The study highlights the need for further research into how environmental plastic contamination may be influencing the rising rates of liver disease worldwide.
Overview of the hazardous impacts of metabolism-disrupting chemicals on the progression of fatty liver diseases.
This review examined how metabolism-disrupting chemicals (MDCs)—including bisphenol A and phthalates from plastics—promote the development and progression of metabolic dysfunction-associated steatotic liver disease (MASLD, formerly NAFLD). MDC exposure was found to impair liver lipid homeostasis and contribute to the global rise in fatty liver disease.
Chronic Nanoplastic Exposure Promotes the Development and Progression of Metabolic Dysfunction‐Associated Steatotic Liver Disease
This study found that chronic exposure to nanoplastics promotes the development and worsening of metabolic dysfunction-associated steatotic liver disease (formerly known as fatty liver disease). Nanoplastics appear to increase vulnerability to liver disease progression. The finding is concerning because fatty liver disease is already widespread, and everyday nanoplastic exposure through food and water could be making it worse.
Microplastics in metabolic dysfunction-associated steatotic liver disease: An emerging threat to liver health
This review examined emerging evidence linking microplastic exposure to the development and progression of metabolic dysfunction-associated steatotic liver disease (MASLD, formerly NAFLD). The authors found that microplastics detected in liver tissue can exacerbate hepatic inflammation, lipid accumulation, and oxidative stress through multiple mechanisms, adding a novel environmental risk factor to MASLD pathogenesis.
Chronic Nanoplastic Exposure as a Novel Risk Amplifier for MASLD Progression
This study examines the potential for chronic nanoplastic exposure to amplify the progression of metabolic dysfunction-associated steatotic liver disease. The research explores how persistent nanoplastic exposure may act as a novel risk factor that worsens liver disease outcomes. The findings highlight growing concern about the intersection of plastic pollution and metabolic health conditions.
Sex, Nutrition, and NAFLD: Relevance of Environmental Pollution
This review explores how environmental pollutants, including microplastics and endocrine-disrupting chemicals, may contribute to non-alcoholic fatty liver disease, with differences between men and women. The authors argue that diet and lifestyle changes alone cannot explain the rapid global rise in liver disease, and that chemical exposures deserve more attention. The study highlights how pollutants that disrupt hormones and metabolism could be an underrecognized factor in liver health.
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.
Nanoplastics and MASLD : Unveiling Interorgan Crosstalk and Environmental Modulators
This brief editorial discusses the emerging connection between nanoplastic exposure and metabolic-associated steatotic liver disease (MASLD), a condition involving fat buildup in the liver. It highlights how nanoplastics may act as environmental triggers that affect the liver through interactions with the gut and other organs. As MASLD rates rise globally, understanding whether plastic pollution contributes to liver disease is an important emerging area of research.
Are Ingested or Inhaled Microplastics Involved in Nonalcoholic Fatty Liver Disease?
This review explored the potential connection between microplastic exposure through ingestion and inhalation and nonalcoholic fatty liver disease, which has become a leading cause of chronic liver injury. The study discusses how dietary and environmental microplastic exposure could potentially influence liver health through mechanisms including inflammation and endocrine disruption, though further research is needed to establish definitive links.
Exposure to microplastics and liver oncogenesis: A comprehensive review on molecular mechanisms and pathogenic pathways
Researchers reviewed mechanisms by which microplastic exposure may promote liver cancer, identifying oxidative stress, mitochondrial dysfunction, inflammatory signaling, and epigenetic disruption as key pathways, while noting that microplastics can also carry heavy metals and organic pollutants that synergistically amplify hepatotoxic and carcinogenic risk.
Exploring the micro- and nanoplastics–diabetes nexus: Shattered barriers, toxic links, and methodological horizons
This review examines growing evidence that micro- and nanoplastics may contribute to diabetes by disrupting blood sugar regulation, insulin signaling, and fat metabolism through oxidative stress and inflammation. Animal studies show that plastic particles can damage the pancreas, liver, and gut in ways that mirror the development of diabetes, though human studies are still limited. The review calls for more research into whether everyday microplastic exposure could be a hidden factor in the global rise of metabolic diseases.
Nanoplastics Toxicity Specific to Liver in Inducing Metabolic Dysfunction—A Comprehensive Review
This review examines how nanoplastics, particles smaller than 100 nanometers, accumulate in and damage the liver. Researchers found that nanoplastics enter the body through the respiratory and digestive systems, reach the liver via the bloodstream, and can disrupt the gut-liver axis and gut microbiome. The evidence suggests that liver damage from nanoplastics may trigger cascading effects on other organs, highlighting the need for further research on these less visible pollutants.
Non-parenchymal cells: key targets for modulating chronic liver diseases
This review examines how specialized non-parenchymal cells in the liver drive chronic liver diseases like fatty liver disease, fibrosis, and cirrhosis through inflammation and scarring. While not directly about microplastics, these are the same cell types and disease pathways that microplastics and nanoplastics have been shown to activate when they accumulate in liver tissue. Understanding these mechanisms helps explain how environmental pollutants like microplastics could contribute to the growing burden of chronic liver disease.
Chronic PET‐Microplastic Exposure: Disruption of Gut–Liver Homeostasis and Risk of Hepatic Steatosis
Researchers exposed mice to PET microplastics ground from plastic bottles over 29 weeks and found that the particles caused obesity, liver enlargement, fatty liver disease, and early-stage scarring of liver tissue. The microplastics also disrupted gut bacteria and bile acid metabolism, pointing to damage along the gut-liver connection. The findings raise concerns about the long-term health effects of chronic exposure to the type of microplastics commonly found in food and beverages.
A review of environmental metabolism disrupting chemicals and effect biomarkers associating disease risks: Where exposomics meets metabolomics
This review examines how environmental chemicals, including contaminants associated with plastics, can disrupt human metabolism and contribute to conditions like obesity and diabetes. Researchers mapped the connections between chemical exposure and changes in metabolic biomarkers that signal disease risk. The study highlights the emerging field of metabolism-disrupting chemicals and the importance of understanding how everyday environmental exposures influence long-term metabolic health.
Emerging threat of environmental microplastics: A comprehensive analysis of hepatic metabolic dysregulation and hepatocellular damage (Review)
This review summarizes existing research on how microplastics damage the liver, which is a key organ for filtering toxins from the body. Studies show that microplastics can cause liver tissue damage, trigger cell death, and disrupt fat metabolism, with smaller particles and longer exposure causing worse effects. The findings highlight the liver as a particularly vulnerable organ because it accumulates microplastics that enter the body through food and water.
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.
Untargeted metabolomics and transcriptomics joint analysis of the effects of polystyrene nanoplastics on lipid metabolism in the mouse liver
Mice exposed to polystyrene nanoplastics for 12 weeks gained weight without eating more and showed increased cholesterol levels and fat accumulation in their livers. Gene and metabolite analysis revealed that the nanoplastics disrupted fat metabolism pathways in the liver, essentially reprogramming how the body processes and stores fat. These findings suggest that nanoplastic exposure could be a hidden factor contributing to obesity and fatty liver disease in humans.
