Background and Objectives: This study aims to investigate the significance of changes in the expression 11β-hydroxysteroid dehydrogenase (11β-HSD) and glucocorticoid receptor (GR) for the development of Kawasaki disease (KD). Subjects and Methods: Real-time polymerase chain reaction was performed to determine the mRNA expression levels of GR and 11β-HSD in peripheral blood monocytes, both in the acute phase of the disease and after treatment. Western blotting was performed to determine the protein expression levels of GR and 11β-HSD. Results: The expression levels of GRβ, GRβ, and 11β-HSD1 mRNA in the acute phase were significantly higher than levels at baseline (p<0.01) and after treatment (p<0.05). The 11β-HSD2 mRNA levels were lower in the acute phase than in the normal group (p<0.01), and they were significantly higher after treatment than before (p<0.01). Western blot results were consistent with the real-time PCR results. The coronary artery lesion group exhibited significantly different 11β-HSD2 expression levels from that of the group with normal coronary arteries (p<0.01). Conclusion: GR and 11β-HSD expression changes in the acute phase of KD are important factors for regulating inflammatory responses in KD.

B7-H4 is a member of B7 family of co-inhibitory molecules and B7-H4 protein is found to be overexpressed in many human cancers and which is usually associated with poor survival. In this study, we developed a therapeutic vaccine made from a fusion protein composed of a tetanus toxoid (TT) T-helper cell epitope and human B7-H4IgV domain (TT-rhB7-H4IgV). We investigated the anti-tumor effect of the TT-rhB7-H4IgV vaccine in BALB/c mice and SP2/0 myeloma growth was significantly suppressed in mice. The TT-rhB7-H4IgV vaccine induced high-titer specific antibodies in mice. Further, the antibodies induced by TT-rhB7-H4IgV vaccine were capable of depleting SP2/0 cells through complement-dependent cytotoxicity (CDC) in vitro. On the other hand, the poor cellular immune response was irrelevant to the therapeutic efficacy. These results indicate that the recombinant TT-rhB7-H4IgV vaccine might be a useful candidate of immunotherapy for the treatment of some tumors associated with abnormal expression of B7-H4.
