Fig. 7From: Upregulation of leukocyte immunoglobulin-like receptor B4 on interstitial macrophages in COPD; their possible protective role against emphysema formationLILRB4-decifient mice enhanced MMP-12 mRNA expression. a MMP-12 mRNA expression in the whole lung between wild-type mice and LILRB4−/− mice on day 7 after elastase administration. The mean value of WT was set to 1. N = 8 per groups. b MMP-12 mRNA expression between LILRB4-positive IMs and LILRB4-negative IMs. N = 6 per group. Data are presented as median with a dot for each sample. Statistical comparisons were analyzed by Mann–Whitney U test. WT wild-type mice, KO LILRB4-deficient miceBack to article page
