ClearEffects of microplastics on allergic airways and potential pathogenesis: a review
This review examines how microplastics, which can enter the body through breathing, eating, and skin contact, may affect allergic airway conditions. Researchers found evidence that microplastics can damage airway lining cells, disrupt the protective barrier of the respiratory tract, and trigger heightened airway reactivity. The study suggests that chronic microplastic exposure may worsen allergic airway inflammation, though more research is needed to fully understand the mechanisms involved.
Airway exposure to microplastics: Potential mechanisms from epithelial barrier damage to the development of allergic rhinitis
This review summarized the mechanisms by which airborne microplastic exposure triggers allergic rhinitis, identifying pathways including physical and chemical disruption of the airway epithelial barrier, oxidative stress from adsorbed pollutants, and induction of Th2 immune responses and IgE class-switching. The findings support airborne MPs as a novel trigger for upper respiratory allergic disease.
Progress in understanding the impact of microplastics on respiratory allergic diseases
This review synthesized evidence on how airborne microplastics may affect respiratory allergic diseases such as allergic rhinitis and asthma. Researchers found that inhaled microplastics can compromise airway barriers by disrupting tight junctions, impairing mucus clearance, and weakening mucosal defenses. The study suggests that microplastic characteristics like polymer type, particle size, and surface chemistry influence how they initiate or worsen respiratory allergic responses.
Cellular and molecular mechanisms of allergic asthma
Researchers reviewed the cellular and molecular mechanisms behind allergic asthma, finding that rising exposure to environmental pollutants — including microplastics — likely contributes to the disease's increasing prevalence, as pollutants disrupt airway barrier integrity and trigger immune responses that lead to chronic airway inflammation.
Microplastics in Allergic Rhinitis: Multimechanistic Drivers of Barrier Disruption and Immune Dysregulation
This review examines the multimechanistic pathways by which microplastics drive barrier disruption and immune dysregulation in allergic rhinitis, considering how physical and chemical properties of microplastic particles interact with nasal epithelial and immune function. The paper synthesizes emerging evidence on microplastics as a novel contributor to upper airway allergic disease.
Confronting allergies: strategies for combating pollution and safeguarding our health
This review examined the growing body of evidence linking environmental pollutants, including airborne microplastics, to increasing rates of allergic reactions worldwide. Researchers found that air pollution and indoor contaminants can worsen respiratory allergies, while climate change intensifies seasonal allergy patterns. The study emphasizes the need for comprehensive action including government regulation and public awareness to reduce pollution-driven allergy risks.
Impact of Microplastics on Human health: Time for us to get attentive- before it’s too late
This paper reviewed the growing evidence on microplastic impacts on human health, covering ingestion, inhalation, and dermal exposure routes, and the potential for microplastics to cause inflammation, oxidative stress, and endocrine disruption. The authors argue the problem demands urgent regulatory attention.
Epithelial barrier dysfunction, type 2 immune response, and the development of chronic inflammatory diseases
This review explains how everyday substances including microplastics, air pollutants, food additives, and household chemicals damage the protective lining of our body's surfaces (epithelial barriers). Even trace amounts of these substances can cause the barriers to become leaky, allowing bacteria and allergens to trigger chronic inflammation. The research suggests that microplastic exposure, alongside other modern pollutants, may be contributing to the rise in chronic inflammatory diseases over the past several decades.
The potential effects of microplastics on human health: What is known and what is unknown
This review summarizes what is currently known about how microplastics might affect human health, noting that while contamination is widespread in food, water, and air, direct evidence of harm in humans is still limited. Studies in animals and cell cultures suggest microplastics could trigger immune responses, cause inflammation, and affect reproduction and development. The authors call for more rigorous clinical studies to determine whether the levels of microplastics that people actually encounter pose real health risks.
Oral exposure to nano- and microplastics: Potential effects in food allergies?
This review explored whether exposure to nano- and microplastics through food could contribute to the rising rates of food allergies worldwide. Researchers found that these tiny plastic particles may alter the structure of food allergens, increase gut permeability, promote intestinal inflammation, and disrupt the immune system. While direct evidence is still limited, the study suggests that microplastics in the diet could potentially heighten sensitivity to food allergens.
Effect of Microplastic Inhalation on Allergic and Nonallergic Rhinitis
Researchers analyzed nasal lavage samples from rhinitis patients and healthy controls, finding significantly higher microplastic concentrations in both allergic and nonallergic rhinitis groups compared to controls. Younger participants and those with more severe symptoms tended to have higher microplastic levels in their nasal passages. The study suggests that inhaled microplastics may play a role in nasal inflammation, though more research is needed to establish a direct cause-and-effect relationship.
Immunotoxicity 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.
Risk factors for the prevalence and development of allergic diseases
This review synthesized evidence on risk factors for the development of allergic diseases, covering genetic predisposition, early-life microbial exposure, diet, air pollution, and emerging exposures including microplastics. The authors discuss how environmental changes have driven rising allergy prevalence and identify microplastics as a candidate contributing factor warranting further study.
Effects of microplastics on the immune system: How much should we worry?
This review examines how microplastics may affect the human immune system, noting that people are mainly exposed through food and breathing. While early research shows microplastics can trigger inflammation and immune responses in lab and animal studies, the authors stress that more research is needed to understand what this means for human health at real-world exposure levels.
Unraveling the impact of microplastics on autoimmune diseases: hidden dangers and environmental triggers
This review examines the emerging evidence linking microplastic exposure to the development and progression of autoimmune disorders. Researchers found that microplastics can modulate immune gene expression, trigger excessive reactive oxygen species in immune cells, and promote inflammatory cytokine release, potentially creating conditions favorable for autoantibody production. The study highlights microplastics as a plausible environmental trigger for autoimmune conditions, though direct causal evidence in humans remains limited.
