Levels of PI3K, p38 and JAK/STAT markers in bronchial epithelium at baseline and post allergen (n = 11): Bronchial biopsies were collected from 11 asthma patients at baseline and 6 h post allergen challenge, with protein expression analysed in the epithelium (a) by immunohistochemistry. Data presented as mean values with standard deviation. Individual patient’s data for the statistically significant changes in pp38 are shown in (b). Comparisons between baseline and post allergen were by paired T-tests or Wilcoxon tests (#), as appropriate *p < 0.05
