Microplastics and the Immune System: Alex Remels Shares Insights on Recent Findings

A recent study by researchers at the Medical University of Vienna, published in the Journal of Hazardous Materials Advances, highlights how PET microplastics can remain in the lungs of mice, exacerbate respiratory inflammation, and alter immune responses, particularly in the context of allergies. Alex Remels, MOMENTUM researcher and co-leader of Work Package 2, emphasizes that while this study clearly demonstrates the potential for microplastics to provoke immune reactions, it’s important to note that the administration method, via the nose, differs from real-world inhalation exposure.

Remels also stresses the need for more realistic research approaches, such as using a mix of microplastics and accounting for the substances (e.g., microorganisms and heavy metals) that often attach to these particles. Current studies often use high doses to observe effects, but real-world exposure is typically gradual and involves complex mixtures.

This research aligns with MOMENTUM’s mission to better understand the health impacts of micro- and nanoplastics and develop more accurate risk assessments.
