Reduced TM expression in areas of lung inflammation in Wt and TM^pro/pro mice. Immunostaining for TM in the lungs of Wt (A) and TM^pro/pro (B) mice, in lungs 6 hours after LPS administration in Wt (C) and TM^pro/pro (D) mice, 24 hours after K pneumoniae in Wt (E) and TM^pro/pro (F) mice, and 48 hours after S pneumoniae in Wt (G) and TM^pro/pro (H) mice. Slides are representative for n = 5 for each group; magnification, × 20.
