| Sumario: | The aim of this study was to evaluate a possible role of AID (AICDA – activation-induced (cytidine) deaminase) in the bronchial asthma (BA) pathogenesis. Materials and methods. We have examined twelve healthy control persons, forty-two patients with allergic bronchial asthma (ABA) and twenty-seven patients with non-allergic bronchial asthma (NABA). The AID mRNA expression was evaluated by means of RT-PCR. Results: AID mRNA was more significantly expressed in BA, than in healthy controls. Meanwhile, no significant differences were revealed between ABA and NABA groups. Correlation analysis of AID mRNA expression levels in peripheral blood lymphocytes has shown that CHε mRNA and total serum IgE revealed significant negative correlation, in the NABA group only. The levels of AID mRNA expression in peripheral blood lymphocytes exhibited positive and significant correlations with clinical characteristics, reflecting severity and stage of the disease, in BA patients. Moreover, a significant positive correlation was revealed with eosinophil contents in sputum. Conclusion. It was concluded that normal regulation of IgE class switching normally based on feedback regulation, was impaired in ABA but not affected in NABA. |
