Expression of eotaxins in the material from nasal brushing in asthma, allergic rhinitis and COPD patients

► CCL24 is the main eotaxin expressed in the material from nasal brushing (notably in allergic asthma). ► During allergic rhinitis all eotaxins are highly expressed. ► Only expression of CCL26 in the material from nasal brushing correlated with lung function tests. ► A negative correlation the FEF1/FVC factor and CCL26 in asthma. ► A opposite positive correlation between the FEF1/FVC factor and CCL26 in COPD.
