ClearEffects of nanoplastic on cell apoptosis and ion regulation in the gills of Macrobrachium nipponense
Researchers exposed juvenile oriental river shrimp to varying concentrations of nanoplastics and examined effects on gill cell viability and ion regulation. They found that higher nanoplastic concentrations increased cell death rates, decreased ion content, reduced ATPase enzyme activity, and disrupted ion transport gene expression in gill tissues. The study suggests that nanoplastic pollution can impair critical ion regulation functions in freshwater crustaceans, with implications for aquaculture.
Transcriptomic analysis following polystyrene nanoplastic stress in the Pacific white shrimp, Litopenaeus vannamei
Researchers used transcriptomic analysis to study how polystyrene nanoplastics affect gene expression in Pacific white shrimp. They found that nanoplastic exposure activated lysosome pathways and disrupted genes involved in immune response, protein processing, and metabolism. The study provides molecular-level evidence that nanoplastics can interfere with multiple biological systems in commercially important shrimp species.
Revealing the Impact of Polystyrene Nanoplastics on Gill Tissues of the Intertidal Clam, Gafrarium Divaricatum (Gmelin, 1791) using Transcriptomics Approach
Researchers exposed intertidal clams to polystyrene nanoplastics and used transcriptomics to assess gill tissue impacts, finding 1,182 upregulated and 1,626 downregulated genes related to immune modulation, antioxidant defense, and apoptosis. Histopathological examination revealed structural damage to gill tissues including ciliary erosion, lamellae fusion, and lipofuscin accumulation. The study establishes a high-quality genomic resource for this clam species while demonstrating the ecotoxicological effects of nanoplastics on sessile marine bivalves.
Effects of exposure to nanoplastics on the gill of mussels Mytilus galloprovincialis: An integrated perspective from multiple biomarkers
Researchers exposed Mediterranean mussels to polystyrene nanoplastics for seven days and measured multiple gill biomarkers, finding that nanoplastics triggered oxidative stress, inhibited acetylcholinesterase, disrupted sodium-potassium ion transport, and impaired energy and lipid metabolism, pointing to broad physiological interference in marine invertebrates.
Toxicological effects of microplastics in Litopenaeus vannamei as indicated by an integrated microbiome, proteomic and metabolomic approach
Shrimp (Litopenaeus vannamei) exposed to five microplastic types for 14 days showed gut microbiota shifts (increased Bacteroidetes and Proteobacteria, decreased Firmicutes) and altered haemolymph proteomes, with each MP type producing distinct immune pathway effects.
Effects of microplastics on gene expression to nonspecific immune system in pacific white shrimp (Litopenaeus vannamei).
This study found that high-density polyethylene microplastic particles in shrimp feed suppressed immune defense genes in Pacific white shrimp and caused intestinal and gill tissue damage at concentrations well below lethal levels. The findings suggest that microplastic exposure could compromise immune function and health in farmed crustaceans.
Oxidative effects of consuming microplastics in different tissues of white shrimp Litopenaeus vannamei
Researchers fed white shrimp diets containing polystyrene microplastics and found the particles accumulated in gills, muscles, and the hepatopancreas. The microplastics triggered oxidative stress, DNA damage, and lipid damage in multiple tissues, along with visible tissue abnormalities including edema and immune cell infiltration. The study demonstrates that dietary microplastic exposure can cause widespread oxidative harm across different organ systems in commercially important shellfish.
Insight into the immune and microbial response of the white-leg shrimp Litopenaeus vannamei to microplastics
Researchers exposed white-leg shrimp (Litopenaeus vannamei) to different concentrations of microplastics for 48 hours and measured immune and microbial responses. The study found that high microplastic concentrations significantly reduced survival rates, altered immune-related gene expression, and disrupted the gut microbial community, suggesting that microplastic pollution may compromise shrimp immune function.
Evaluation of nanoplastics toxicity in the soil nematode Caenorhabditis elegans by iTRAQ-based quantitative proteomics
Researchers used quantitative proteomics to evaluate nanoplastic toxicity in the nematode C. elegans, identifying disrupted proteins involved in oxidative stress, metabolism, and cellular defense pathways, providing molecular-level insight into how nanoplastics harm organisms.
Transcriptional response in the whiteleg shrimp (Penaeus vannamei) to short-term microplastic exposure
Researchers exposed whiteleg shrimp (Penaeus vannamei) to microplastics for 96 hours and used transcriptomics to profile gene expression changes, finding significant upregulation of stress response, immune, and detoxification pathways, indicating that even short-term microplastic exposure triggers a broad molecular stress response.
Transcriptomic analysis reveals nanoplastics-induced apoptosis, autophagy and immune response in Litopenaeus vannamei
Shrimp exposed to polystyrene nanoplastics for 28 days showed dose-dependent damage to their immune systems, including increased cell death, tissue destruction in the liver-like organ, and disrupted antioxidant defenses. At high concentrations, the nanoplastics overwhelmed the shrimp's ability to fight off threats. Since shrimp are an important food source, these findings raise concerns about the quality and safety of seafood from nanoplastic-contaminated waters.
Gradual effects of gradient concentrations of polystyrene nanoplastics on metabolic processes of the razor clams
Researchers exposed razor clams to a gradient of polystyrene nanoplastic concentrations and used metabolomics to track effects, finding that even low concentrations disrupted energy metabolism and amino acid pathways, with effects becoming more severe as concentration increased.
Toxicity of Ammonia Stress on the Physiological Homeostasis in the Gills of Litopenaeus vannamei under Seawater and Low-Salinity Conditions
This study examined how ammonia stress damages the gills of Pacific white shrimp raised in both seawater and low-salinity conditions. While not directly about microplastics, the findings are relevant because microplastics in aquaculture water can worsen ammonia toxicity, and the gill damage observed -- including disrupted ion balance and immune function -- highlights how environmental stressors compound threats to seafood safety.
Effect of polyethylene microplastics on oxidative stress and histopathology damages in Litopenaeus vannamei
Researchers injected fluorescent polyethylene microspheres into Pacific white shrimp (Litopenaeus vannamei) and found that microplastic exposure increased oxidative stress markers and caused histopathological damage to hepatopancreas and gill tissue, even at relatively low concentrations.

Polystyrene nanoplastics induce lipid metabolism disorder and alter fatty acid composition in the hepatopancreas of Pacific whiteleg shrimp (Litopenaeus vannamei)
Researchers exposed Pacific whiteleg shrimp to different concentrations of polystyrene nanoplastics for 28 days and found significant disruption to fat metabolism in the shrimp's digestive organ. Higher concentrations caused tissue damage, reduced protein and fat content, and altered the activity of enzymes that control how the body processes fats. Since shrimp is a widely consumed seafood, these findings raise questions about how nanoplastic contamination in aquaculture could affect the nutritional quality and safety of shellfish for human consumption.
