Outline of Final Research Achievements

The efficiency of introducing shRNA into bone marrow-derived dendritic cells was extremely poor, and shRNA was introduced using DC 2.4 which is a cell line of dendritic cells. Introduction efficiency was low but better than bone marrow derived dendritic cells. Furthermore, the antigen presenting ability of DC 2.4 was analyzed in vitro, however, activation of T cells and elevation of cytokine production were not observed.
We attempted to prepare an asthma model using antigen - stimulated DC 2.4, but no increase in airway hyperresponsiveness to methacholine, eosinophilic airway inflammation, and elevation of type 2 cytokine in BALF were observed.
From the above, it is concluded that it is difficult to prove the hypothesis in this experimental system.
