Abstract : The localization and function of T-cells in the inflamed human gingivae were revealed by immunopathological studies. 21 of 40 gingival specimens showed flourescence positive by staining with FITC-labeled rabbit antiserum to human thymocytes. T-cells were mainly detected in the subepithelial connective tissue and partially in the deep layer of the gingiva as a cluster or scatter patte...
