Abstract | BACKGROUND: OBJECTIVE: METHODS: Two different AD model mice (DS-Nh and NC/Nga) received MIF- DNA vaccination to analyze preventive and therapeutic effects, as assessed by clinical skin scores, histologic findings, and serum IgE levels. RESULTS: In murine models of AD, MIF- DNA vaccination prevented the occurrence of the AD skin phenotype. Furthermore, administration of MIF- DNA vaccine to mice that had already developed AD produced a rapid improvement in AD skin manifestation. There were reduced histologic signs of inflammation and lower serum IgE levels in treated mice compared with those seen in control animals. Finally, passive transfer of IgG from MIF- DNA vaccinated mice to AD mice also produced a significant therapeutic effect. These results demonstrate that MIF- DNA vaccination not only prevents the development of AD but also improves the symptoms of pre-existing AD. CONCLUSION: Taken together, the induction of an anti-MIF autoantibody response using MIF- DNA vaccination appears to be a useful approach in the treatment of AD.
