Adjuvant-Free Murine Models of Allergic Sensitization to the Major Soybean Allergen Gly m 4.

ABSTRACT: Gly m 4, a soybean PR-10 allergen, is known to trigger systemic allergic reactions. However, the intrinsic sensitizing potential of the allergen remains unclear. Adjuvant-free murine models of sensitization to Gly m 4 might help to investigate mechanisms of a soy allergy and establish relevant in vivo platforms for developing novel allergen-specific immunotherapy strategies. BALB/c mice were sensitized to Gly m 4 via intraperitoneal (i.p.), subcutaneous (s.c.), or intranasal (i.n.) routes, with or without adjuvant (alum or lipopolysaccharide (LPS)). In order to assess sensitization, we evaluated levels of allergen-specific IgE, IgG1, IgG2a, systemic anaphylaxis, rat basophil (RBL) degranulation, and cytokine/chemokine profiles in mouse sera. I.n. exposure with or without LPS proved to be i
