Figure 3 shows representative images of hematoxylin stained lung sections at 5X or 20X magnification demonstrating severe inflammatory response in CF mice and reduced infiltrate in subsequent groups (A) and Wright-Giemsa stain of BAL fluid harvested at day 3 which shows a denser infiltrate of white blood cells and a higher proportion of neutrophils to monocytes in CF infected mice compared to CF/Hdac6, Hdac6 −/−, and WT infected mice (B). Here, HDAC6 is linked to cystic fibrosis.
