Fig. 3From: IRF4 and STAT3 activities are associated with the imbalanced differentiation of T-cells in responses to inhalable particulate mattersIntranausal PM exposure causes inflammatory responses in mouse lung in vivo. a, the schematic view of the animal experiment, each group of six BALB/c mice were treated with PM suspension for 3 days before the lung tissue, BALF and serum were collected and analyzed; b, inflammatory alterations are observed in mouse lung following intranosal treatment of PM suspension; c, comparison of the pathological inflammation score in mouse lung tissue with and without PM treatment; d, Giemsa stain of cells in BALF from mice with and without PM treatment; E, the number of inflammation cells in BALF, include eosinophils, neutrophils, lymphocytes and macrophages.
