| Outline of Final Research Achievements |
We detected oral mucosa keratinocytes cultured in a tissue culture dish do not express FasL by immunocytochemistry, FACS and RT-PCR analyses. The pharmacological induction of FasL expression was not successful, either. This resulted in the difficulty in developing an in vitro model of oral lichen planus by utilizing a characteristic of immune-privilege. However, we found that approximately 10% of human T cells expressed FasL. This suggestied it may be possible to analyze the T cell-oral keratinocyte pathophysiological interation in vitro.
