ClearImmunotoxicity and intestinal effects of nano- and microplastics: a review of the literature
This review examines the evidence on how nano- and microplastics affect the immune system and intestinal health. The findings suggest that exposure to these particles can disrupt the gut microbiome and impair critical intestinal barrier functions, potentially contributing to the development of chronic inflammatory and immune conditions.
The role of gut microbiota in MP/NP-induced toxicity
This review summarizes how micro- and nanoplastics disrupt gut bacteria and why that matters for overall health. The tiny plastic particles change the composition and function of the gut microbiome, which can trigger inflammation, weaken the intestinal barrier, and potentially contribute to diseases beyond the gut through the immune and nervous systems.
Effect of micro- and nanoplastics as food contaminants on the immune system
This review synthesized research on how microplastic and nanoplastic exposure affects immune system function, finding evidence across multiple studies that these particles can modulate immune responses and trigger inflammatory pathways in exposed organisms. The authors highlight immune disruption as an emerging health concern from micro- and nanoplastic contamination.
Perturbation of gut microbiota plays an important role in micro/nanoplastics-induced gut barrier dysfunction
Researchers investigated how micro- and nanoplastics disrupt gut barrier function in mice, finding that different surface chemistries caused varying levels of damage. The study suggests that these plastic particles harm the gut by altering the gut microbiome, which then leads to inflammation and weakening of the intestinal barrier that normally keeps harmful substances out of the body.
Micro- and Nanoplastics as Emerging Environmental Materials: GreenChemistry Insights into Gut Microbiota Disruption and Chronic DiseasePathways
Researchers reviewed how micro- and nanoplastics accumulate in the gastrointestinal tract and disrupt gut microbiota composition, finding evidence linking these exposures to reduced microbial diversity, gut barrier dysfunction, systemic inflammation, and potential contributions to chronic diseases including metabolic disorders and neurodegeneration.
[Effect of microand nanoplastics on the gastrointestinal mucosa and intestinal microbiome].
This review examines how micro- and nanoplastics entering through the food chain affect the gastrointestinal tract, finding evidence of disruption to gut mucosal integrity and intestinal microbiome composition, with implications for digestive health and systemic immune function.
A systematic review on the effects of nanomaterials on gut microbiota
This systematic review of 68 studies found moderate evidence that zinc-based, copper-based, and silver nanomaterials cause gut microbiota dysbiosis, while titanium dioxide nanoparticles showed variable effects depending on crystal form and dose. The gut microbiome's response to nanomaterials depended heavily on particle composition, size, dose, and exposure duration. These findings are directly relevant to microplastic research, as ingested micro- and nanoplastics similarly interact with gut bacteria and may alter the microbiome composition that influences immune function and overall health.
Micro(nano)plastics and their potential impact on human gut health: a narrative review
This narrative review synthesizes evidence on how microplastics and nanoplastics affect the human gut, discussing ingestion routes, gut barrier interactions, microbiome disruption, and potential systemic health effects.
The ant that may well destroy a whole dam: a systematic review of the health implication of nanoplastics/microplastics through gut microbiota
This systematic review summarizes existing research on how nanoplastics and microplastics disrupt gut bacteria in various organisms. The findings show that plastic particle exposure consistently alters gut microbiome composition, which in turn affects the host's immune function, metabolism, and overall health. These gut bacteria changes may be a key pathway through which microplastics harm human health.
Untoward Effects of Micro- and Nanoplastics: An Expert Review of Their Biological Impact and Epigenetic Effects
This expert review examined the biological and epigenetic effects of micro- and nanoplastics on living organisms. The study suggests that while intestinal uptake of plastic particles appears relatively low and size-dependent, nanoplastics may dysregulate molecular signaling pathways, alter gut microbiota composition, and induce transgenerational epigenetic changes potentially linked to metabolic disorders.
Uncovering the nexus of human health hazards of nanoplastics, gut-dysbiosis and antibiotic-resistance
This review provides the first comprehensive synthesis specifically linking nanoplastic exposure to gut dysbiosis and antibiotic resistance gene propagation, finding that nanoplastics suppress beneficial microbes while fostering pathogens and creating conditions that promote horizontal transfer of resistance genes.
Micro(nano)plastics and Their Potential Impact on Human Gut Health: A Narrative Review
This review summarizes research on how micro- and nanoplastics affect the gut, finding that they can damage the intestinal lining, trigger immune responses, and disrupt the balance of beneficial gut bacteria in both cell studies and animal models. Since humans are primarily exposed to microplastics through food and food packaging, understanding these gut effects is essential for assessing the true health risks of plastic pollution.
Gut microbiota, a key to understanding the knowledge gaps on micro-nanoplastics-related biological effects and biodegradation
This review explores how micro- and nanoplastics affect the community of microorganisms living in the gut, and how those same gut microbes might be able to break down plastic particles. Swallowed microplastics can disrupt the balance of gut bacteria, potentially leading to various diseases. On the other hand, some gut bacteria can actually degrade plastics into smaller, less harmful molecules, opening a possible avenue for biological cleanup.
Immunotoxicity by Microplastics
This review examines how microplastics and nanoplastics, after entering the body through the gut, lungs, or skin, can disrupt the immune system by triggering inflammation, causing oxidative stress (cellular damage from unstable molecules), and impairing immune cell function, while highlighting major gaps in our understanding of these long-term health effects.
Microplastics and their interactions with microbiota
This review examines how microplastics interact with microbiota (the communities of microorganisms in the environment and in living bodies). Microplastics can carry harmful bacteria and disrupt the natural balance of microbial communities in soil, water, and the human gut. The disruption of gut microbiota by microplastics is particularly concerning because a healthy gut microbiome is essential for immune function, digestion, and overall health.
Micro(nano)plastics in food system: potential health impacts on human intestinal system.
This review assessed how micro(nano)plastics in the human food system reach the intestine and accumulate in the gut, summarizing evidence that they can alter intestinal barrier function, trigger inflammation, and disrupt the gut microbiome, with implications for long-term digestive health.
How do microplastics affect the composition and function of gut microbiota?
Researchers reviewed how microplastics may disrupt gut microbiota composition and metabolic function, noting that while dysbiosis is a likely outcome of exposure, the full scope of these effects in humans remains understudied.
Innovative mechanisms of micro- and nanoplastic-induced brain injury: Emphasis on the microbiota-gut-brain axis
This review summarizes how micro- and nanoplastics may damage the brain through the gut-brain axis, a communication pathway between the digestive system and the nervous system. Nanoplastics can disrupt gut bacteria and weaken the intestinal barrier, potentially sending inflammatory signals to the brain. The authors suggest that targeting gut health could be a way to reduce brain damage caused by nanoplastic exposure.
Gut microbiota as an emerging target for the health implications of microplastics
This review examines how microplastic exposure disrupts the gut microbiome, finding evidence that microplastics damage intestinal barrier proteins, promote inflammation and oxidative stress, and may drive systemic effects including neurotoxicity and reproductive toxicity through gut-mediated pathways.
Health risk analysis of micro-and nanoplastic exposure via the microbiota-gut-brain axis
This review examines how micro- and nanoplastics that accumulate in the gastrointestinal tract may disrupt the microbiota-gut-brain axis through neural, immune, and endocrine pathways. The study suggests that these particles can interfere with normal gut microbiota function after entering the body through diet, inhalation, and skin contact, potentially inducing or worsening health effects.
