| Outline of Final Research Achievements |
We previously found that dental pulp cells produces molecules inducing tumor necrosis factor alpha from macrophages, and named this factor Dental Pulp Cell-derived Tumor Necrosis Factor-α Inducing Factor: DPTIF. In this study, we aimed to unvail the nature of this molecule and to investigate the posibble receptor and/or binding proteins. The results indicated that DPTIF contains trypsin sensitive protenous molecule but is associated with extracelluler microvesicles. Therefore, it appeared that DPTIF is directly incorporated into macrophages rather than binding to the cell surface receptor.
