Abstract

Der p 2 is the major allergen of the house dust mite (HDM) associated with the development of allergic diseases. The pathogenic mechanism of the allergy is related to cytokine release of lymphocytes and constitutive apoptosis of neutrophils. In the present study, we examined whether Der p 2 induces cytokine release of lymphocytes, which is involved in regulation of neutrophil apoptosis. In normal and allergic subjects, Der p 2 enhanced the secretion of IL-6, IL-8, MCP-1, and GM-CSF in a time-dependent manner. Although Der p 2 was weakly effective against neutrophil apoptosis, conditioned media collected from normal and allergic lymphocytes after Der p 2 treatment inhibited the apoptosis of normal and allergic neutrophils. Der p 2 showed stronger inhibition of apoptosis of allergic neutrophils cocultured with allergic lymphocytes than normal neutrophils cocultured with normal lymphocytes. These findings improve our understanding of the role of Der p 2 in regulation of lymphocytes and neutrophils and will enable elucidation of allergy pathogenesis.
