title: [Preventive effect of IL-18 gene modified mature dendritic cells vaccine on airway inflammation in mouse asthma model].
abstract: To investigate the preventive effect of interleukin-18 (IL-18) gene modified mature dendritic cells (mDC) vaccine on airway inflammation in mouse asthma model.
  
  
  
  The asthma model was induced by injection of ovalbumin (OVA) in BALB/c mice. IL-18 gene modified mouse mature dendritic cells (mDC) were detected by flow cytometry and its capacity of inducing allogeneic T cell responses was examined by mixed lymphocyte reaction (MLR). The OVA-induced asthmatic mice were randomly divided into 6 groups: PBS group, DXM group, mDC group, Ad-LacZ-mDC group, Ad-IL-18-mDC group and control group. The pathological changes in lung tissues were assayed by HE and AB-PAS staining. The numbers of inflammatory cells and percentage of eosinophils (EOS) in bronchoalveolar lavage fluid (BALF) were counted. The levels of IFN-γ IL-4 and IL-13 in culture supernatant of splenocytes were measured by ELISA method. The percentage of CD4(+)CD25(+)Foxp3(+) Treg was assessed by flow cytometry analysis.
  
  
  
  The vaccine was effective in decreasing the infiltration of EOS and accumulation of airway goblet cells in lung tissues, the numbers of inflammatory cells and percentage of EOS in BALF, and the levels of IL-4 and IL-13 in culture supernatant of splenocytes, and in increasing the levels of IFN-γ in culture supernatant of splenocytes and the percentage of CD4(+)CD25(+)foxP3(+) reg.
  
  
  
  IL-18 gene modified mDC vaccine has a preventive effect on airway inflammation in OVA-induced asthmatic mice.
