Alternatively activated macrophages are induced during rMA15 infection of LysM/STAT1^−/− mice but not FoxJ/STAT1^−/− mice. IHC was performed in lung sections from LysM/STAT1 and FoxJ/STAT1 mice after either PBS inoculation or rMA15 infection at 9 days p.i. The sections were stained for the alternatively activated macrophage markers FIZZ1 and YM1. The images showing 10× resolution focused on airway labeling, and those at 40× resolution focused on the pulmonary interstitium to highlight the extent of signal.
