  • Title: Lymphocyte-epithelial cell interactions in oral mucosal inflammatory diseases.
    Author: Rogers RS, Movius DL, Pierre RV.
    Journal: J Invest Dermatol; 1976 Nov; 67(5):599-602. PubMed ID: 977990.
    Abstract:
    Lymphocyte cytotoxicity for target cells is a method for evaluating specific lymphocyte stimulation. In vitro lymphocytotoxicity has been demonstrated in chronic ulcerative colitis and granulomatous colitis, polymyositis and dermatomyositis, systemic scleroderma, recurrent aphthous stomatitis, and periodontal disease. We have investigated lymphocytotoxicity in 36 patients with various oral inflammatory diseases using an automated cell-counting system. This investigation demonstrated in vitro lymphocytotoxicity for gingival epithelial target cells by aggressor lymphocytes harvested from patients with recurrent aphthous stomatitis and periodontal disease. This effect was not seen when the lymphocytes were harvested from normal subjects or from patients with other oral mucosal inflammatory diseases. The automated cell-counting system corresponded very well with the assay technique of exclusion of supravital dye.
