Abstract

PURPOSE

To investigate the effects of epinastine on eosinophil chemotaxis and changes in eosinophil adhesion molecules induced by epinastine and three other antiallergic agents, using eosinophils of atopic dermatitis (AD) patients.

RESULTS

Epinastine reduced eosinophil chemotaxis toward eotaxin when the eosinophils had been prestimulated with interleukin (IL)-5, but given alone it did not alter eosinophil chemotaxis toward IL-5. CD11b expression was inhibited when peripheral blood was prestimulated with IL-5, but eosinophil adhesion molecule expression was not altered.

CONCLUSIONS

Epinastine suppresses allergic inflammation not only through its strong antihistamine and antimediator effects, but also by inhibiting eosinophilic chemotaxis and the expression of adhesion molecules involved in chemotaxis, especially CD11b.
