Inhaled corticosteroids attenuate some but not all characteristics of chronic asthma.

<p>Mice were sensitised and challenged for six weeks with PBS or OVA (black bars). OVA treatment was continued for another eight weeks (light grey bars), with or without parallel treatment with inhaled corticosteroids (ICS). OVA treatment was then continued for another 4 weeks without ICS application (dark grey bars) (Protocol C). Data are presented as mean ± SEM of n = 6–8 animals per group, *p≤0.05, **p≤0.01, ***p≤0.001.
