Inflammatory Effects of Microplastics and Nanoplastics on Nasal Airway Epithelial Cells
Summary
Researchers found that polystyrene micro- and nanoplastics cause inflammatory cytokine responses in nasal epithelial cells even over short exposure periods. The study also observed ciliary blunting and transcriptional evidence of significant inflammation and stress responses, suggesting that the nasal airway is vulnerable to plastic particle exposure.
PS MNPs cause inflammatory cytokine responses in nasal epithelial cells over even a short timeframe, in addition to ciliary blunting and transcriptional evidence of significant inflammation and stress response. This sinonasal model can help answer critical questions about the pathogenicity of plastic exposures.

The Effects of Microplastics and Nanoplastics in the Nasal Airway and Upper Respiratory Tract
This review examines the effects of airborne microplastics on the upper respiratory tract and nasal region, an area largely overlooked despite being the initial point of contact with inhaled particles. The literature collectively indicates that microplastics may cause changes in cell morphology, cytotoxicity, and inflammatory effects in nasal tissues, with potential impacts on patient quality of life.
Acute Exposure to Aerosolized Nanoplastics Modulates Redox-Linked Immune Responses in Human Airway Epithelium
Researchers exposed a 3D model of human airway tissue from 14 healthy donors to aerosolized polystyrene nanoplastics over three days and found that while the particles did not cause structural damage, they triggered changes in immune-related gene expression. The nanoplastics activated oxidative stress pathways and altered the expression of genes involved in inflammation and antioxidant defense. The study suggests that even short-term inhalation of nanoplastics could subtly shift immune responses in the airways.
Correspondence Regarding “Inflammatory Effects of Microplastics and Nanoplastics on Nasal Airway Epithelial Cells”
This correspondence comments on a study showing that microplastics and nanoplastics trigger inflammation in nasal airway cells, with effects varying by particle size and surface charge. The author highlights the study's value for understanding how inhaled plastic particles may harm the respiratory system.
Evaluation of nasal microplastic densities in patients with acute and chronic rhinitis
Researchers compared microplastic concentrations in the nasal passages of patients with acute versus chronic rhinitis. They found higher microplastic densities in patients with acute inflammation, suggesting that these particles may play a role in triggering or worsening nasal flare-ups. The findings point to a need for further research into how inhaled microplastics could affect upper respiratory health over time.
Hazard Assessment of Polystyrene Nanoplastics in Primary Human Nasal Epithelial Cells, Focusing on the Autophagic Effects
Researchers exposed primary human nasal epithelial cells to polystyrene nanoplastics of two sizes and found that the smaller particles caused more significant cellular changes, including activation of autophagy pathways. The nanoplastics triggered oxidative stress and altered cell processes related to waste recycling within cells. The study highlights the potential health risks of inhaling airborne nanoplastics, an exposure route that remains understudied.
