Reduced cellular infiltration and chemokine expression in Cd2−/− mice challenged with HDME. (A,B) BALF from WT and Cd2−/− mice injected with PBS or challenged with HMDE were analyzed for total leukocyte counts (TLC, A) and diffential cell counts (showing total monocytes, eosinophils, monocytes, neutrophils, and lymphocytes, B). Data is shown as mean ± SEM and pooled from 4 independent experiments with a total of 10–16 mice per cohort. (C,D) Lung tissue homogenates of WT and Cd2−/− mice injected with PBS or HMDE were analyzed for mRNA levels of Ccr8 (C) and various neutrophil (D) and eosinophil chemokines (E) by qPCR. Data is shown as mean fold change ± SEM and pooled from 3 independent experiments with a total of 8–13 mice per cohort. Statistical significance was determined by Student's unpaired t-test with Welch's correction. *p ≤ 0.05, **p ≤ 0.01.
