%X background. allergic asthma is one of the most prevalent childhood diseases. this disease is characterized by airway inflammation and remodelling. the mechanisms implicated in the pathogenesis of this disease remain unclear. several studies have shown that tgf-¦Â plays an important role in the pathogenesis of asthma. in addition, the polymorphism of the tgf-¦Â promoter region results in the overexpression of tgf-¦Â via regulation of the transcription factor yin-yang-1 (yy1). it is has recently been demonstrated that yy1 may be involved in the pathogenesis of asthma by the regulation of il-4 and il-10. the aim of this study was to evaluate the association between the yy1 and tgf-¦Â expression levels in a murine model of lung allergic inflammation. methods. in this study we used a lung allergic inflammatory murine model with different severity degrees. tissue microarray technology and immunohistochemistry were used to evaluate yy1 and tgf-p expression. the density expression was measured by quantitative methods using specific software. results. expression of both proteins correlated with the degrees of severity of lung allergic inflammation. a similar result was observed with mucus production. conclusions. these results corroborate the role of yy1 and tgf-p in the pathogenesis of this disease.
