Oral Exposure to Polypropylene Microplastics Exacerbates Cow’s Milk Allergy in a Murine Model by Skewing the DCs/T-Cell Response toward Th2 Polarization

DCs/T-cell coculture system confirmed that PP enhanced antigen uptake by DCs and shifted naïve T-cell differentiation toward Th2 polarization, eventually aggravating CMA susceptibility. This study highlighted the potential health risk posed by NMPs contamination in food and suggested a possible contribution to the escalating prevalence of CMA in infants.
