Figure 1. pSmad2 expression baseline and post allergen.

Figure 1

pSmad2 (1A) expression in airway epithelium in response to allergen challenge at the 24 hour time point is summarised. Representative photomicrographs from a paired volunteer at baseline and 24 hours post-allergen are given (1B-C ×20 magnification). Representative photomicropgraph of activin-A expression in the airway (1D ×40) and co-localisation (brown via DAB) to elastase+ positive neutrophils (Fast Red) (1E ×100) is given.
