The proportion of CD11b+Gr-1+(high) neutrophils in the BALF and the lung cell of CFD-induced COPD in mice was higher than that in the normal control group, whereas the proportion of these cells in mice treated with GG, AR, GG plus AR, GA, and TN was lower than that in the CFD-induced control mice (Figure 6A–D). Here, ITGAM is linked to chronic obstructive pulmonary disease.
