Aerosol challenge generates an intense allergic response characterized by eosinophilic airway and lung inflammation mucus hypersecretion and OVA-specific antibody responses . After recuperation, chronic lung inflammatory infiltrates 84573-16-0 remain and respond to re-exposure to OVA leading to disease exacerbation for the lifetime of the mouse. To test the adjuvant effect of aAI peas, we gavaged mice twice weekly for 4 1494675-86-3 cost consecutive weeks with the transgenic aAI and nGM peas, Tendergreen beans or PBS before disease initiation and exacerbation. Na?��ve mice had healthy lungs and no aAI immune responses . PBS control mice , however, illustrate the response to OVA with approximately 30 and 40 eosinophils within the airways for disease initiation and exacerbation, respectively, while neither pea nor bean feeding influenced OVA-induced airway inflammation at either phase of disease . Consumption of peas and beans did not affect the OVA-specific eosinophilic inflammation, mucus secretion or severity of lung inflammation seen on and PAS-stained tissue sections . Antibody responses to OVA were unaffected by feeding aAI pea and bean . In summary, our results show that there is variation in antibody responses to aAIs, but that there was not an increased antibody response to the aAIs from transgenic legumes compared to the aAIs from beans. aAIs from transgenic legumes and beans have minor differences in post-translational modifications that appear to modify immunogenicity . However, we show here that these differences in immunogenicity did not differentiate aAIs from transgenic legumes with those found in beans. All aAIs induced high IgG1 antibody titres and are thus, immunogenic irrespective of transgenic or non-transgenic source. In feeding experiments, we observed that mice fed transgenic and non-transgenic legumes had immune and allergic responses that were similar to those generated by both Pinto and Tendergreen beans. Furthermore, the responses to the non-transgenic peas were related to a crossreactive response to pea lectin and the consumption of transgenic, non-transgenic and bean seed meals did not accentuate allergic responses to another non-cross-reactive allergen. Our results are at odds with the previous study in which mice developed allergic re
