Inhibitory effects of lodoxamide on eosinophil activation.

Recent reports describe the beneficial use of lodoxamide, an anti-allergic compound, for the treatment of asthma and allergic conjunctivitis. Lodoxamide is known as a mast cell stabilizer, however, the association of a significant clinical improvement with a specific decrease in eosinophil infiltrate suggested possible direct effects of lodoxamide on eosinophils. The chemotactic response of eosinophils to fMLP as well as to IL-5, in vitro, was very significantly and dose-dependently inhibited by Lodoxamide. Lodoxamide was also able to strongly inhibit the release of eosinophil peroxidase after IgA-dependent activation and, to a lesser extent, the release of eosinophil cationic protein and eosinophil-derived neurotoxin. Moreover, the release of cytotoxic mediators evaluated in an antibody-dependent cytotoxicity assay against parasitic targets was also significantly reduced, not only in the case of human eosinophils but also in a rat eosinophil-mast cell model of cytotoxicity. Taken together, these results indicate that lodoxamide can exert potent inhibitory effects on eosinophil activation in vitro combined with a strong inhibition of eosinophil attraction, leading therefore to a reduction in their pathological potential in vivo.[1]
