The results revealed that transfer of DXM/lactoferrin PMN-MDSCs, Con PMN-MDSCs, and tumor PMN-MDSCs transfer and treatment with DXM decreased the bronchoalveolar lavage fluid (BALF) cell count (Fig. 7b), eosinophil granulocyte percentage (Fig. 7c), pathological grade (Fig. 7d, e), and IL-4 concentration (Fig. 7f). This evidence concerns the gene IL4 and neoplasm.
