In a separate study, an inhalation exposure of XNRI MWNT-7 with 4 h per day for four consecutive days at a dose range of 6.2–8.2 mg/m3 induced strong pulmonary eosinophilia in mice, accompanied by induction of Il13, Il5, Ccl11, Ccl24, and Ccl17 gene expression, which supports a stimulating effect of MWCNTs on eosinophilia (77). Here, IL13 is linked to Increased total eosinophil count.
