Abstract
Background: IL-31, a recently discovered member of the gp130/IL-6 cytokine family, is mainly expressed by human
mast cells and T helper type 2 cells. IL-31 is a key trigger of atopic dermatitis. Recent studies also suggest a role of
IL-31 in the pathogenesis of other allergic diseases including allergic rhinitis. In the present study we studied the
release of IL-31 and IL-13 in allergen-challenged allergic rhinitis patients.
Methods: Seven seasonal allergic volunteers underwent unilateral nasal provocation with allergen (and a control
challenge) with the disc method out of the allergy season. Nasal symptom scores (rhinorrhea, itching, sneezing,
obstruction) and bilateral nasal secretions were quantified before and after allergen provocation. IL-13 and IL-31 in
nasal secretions and serum were measured by electrochemiluminescent immunoassay or ELISA, respectively.
Results: Nasal allergen challenge induced the typical clinical symptoms and physiological changes. IL-31 and IL-13
in nasal secretions increased in four and five, respectively, volunteers at 5 h after allergen but not after control
challenge. We observed correlation trends between nasal IL-31 concentrations and IL-13 concentrations (r = 0.9,
p = 0.002), and IL-31 contents and sym
