Abstract

Objective: To investigate the effect of intrapulmonary regulatory peptides on adhesion of eosinophils (EOS) to bronchial epithelial cells (BECs).

Methods: Two regulatory peptides, namely vasoactive intestinal peptide (VIP) and epidermal growth factor (EGF) were investigated. VIP and EGF were observed on the secretion of ILs and expression of intercellular adhesion molecule-1 (ICAM-1).

Results: VIP and EGF could decrease ILs secretion and ICAM-1 expression.

Conclusion: VIP and EGF inhibited the adhesion of EOS to BEC in the inflammatory process to lighten the airway inflammation.
