In conclusion, we have identified elevated expression of messenger ribonucleic acid encoding RANTES and monocyte chemotactic protein-3 in the bronchial mucosa of atopic asthmatic patients relative to controls. These findings are compatible with the hypothesis that eosinophil-active beta-chemokines play a role in the mechanism of eosinophil recruitment to the asthmatic bronchial mucosa. ER -
