  • Influence of the route of allergen administration and genetic background on the murine allergic pulmonary response AMERICAN JOURNAL OF RESPIRATORY AND CRITICAL CARE MEDICINE Zhang, Y., Lamm, W. J., Albert, R. K., Chi, E. Y., Henderson, W. R., Lewis, D. B. 1997; 155 (2): 661-669

    Abstract:

    We used various ovalbumin sensitization and challenge protocols to determine the importance of the route of allergen administration and the genetic background in modulating the physiologic, inflammatory, and immunologic features characteristic of allergen-induced asthma. In BALB/c mice, induction of maximal airway hyperresponsiveness and airspace eosinophilia required administration of ovalbumin by both the intraperitoneal and the intranasal routes (combination protocol), whereas intraperitoneal immunization alone resulted in maximal ovalbumin-specific IgE plasma levels. Thus, a systemic immune response to allergen, in addition to, or independent of IgE production, as well as local allergen challenge were necessary for maximal induction of pulmonary disease. BALB/c mice treated with ovalbumin by the combination protocol had increased Th2-type cytokine mRNA levels in bronchial lymph node tissue compared with control mice. In contrast, C57BL/6 mice treated with ovalbumin by the combination protocol had significantly decreased responses compared with BALB/c mice for all parameters of allergic pulmonary disease examined, with the exception of airspace eosinophilia. Genetic background has a striking and selective effect on the phenotype of murine allergic pulmonary disease. Further analysis of this murine model should be useful in helping define the critical pathogenetic events in allergen-induced asthma.
