Cellular hypersensitivity to oral lichen planus lesions in vitro. 1977

P Holmstrup, and M Soborg

The purpose of the present investigation was to demonstrate in vitro cellular hypersensitivity to oral lichen planus lesions. Twenty oral lichen planus patients and 20 control persons matched by and sex were examined by the leukocyte migration agarose technique with tissue extracts from oral lichen planus lesions, normal oral mucosa and normal human kidney, the two latter extracts serving as control antigens. The female lichen planus patients showed statistically significant (P=0.004) migration inhibition with extracts from oral lichen planus lesions, which supports the hypothesis of cellular hypersensitivity to oral lichen planus lesions. However, the male lichen planus patients did not show any significant reaction. No significant reaction was found with the control antigens. The findings do not exclude the hypothesis of cellular hypersensitivity to oral lichen planus lesions. Furthermore, they do not support the hypothesis of oral lichen planus being an autoimmune disease.

D008010 Lichen Planus An inflammatory, pruritic disease of the skin and mucous membranes, which can be either generalized or localized. It is characterized by distinctive purplish, flat-topped papules having a predilection for the trunk and flexor surfaces. The lesions may be discrete or coalesce to form plaques. Histologically, there is a "saw-tooth" pattern of epidermal hyperplasia and vacuolar alteration of the basal layer of the epidermis along with an intense upper dermal inflammatory infiltrate composed predominantly of T-cells. Etiology is unknown. Cutaneous Lichen Planus,Lichen Planopilaris,Lichen Ruber Planus,Mucosal Lichen Planus,Lichen Rubra Planus,Lichen Planus, Cutaneous,Lichen Planus, Mucosal,Planopilaris, Lichen

D009061 Mouth Mucosa Lining of the ORAL CAVITY, including mucosa on the GUMS; the PALATE; the LIP; the CHEEK; floor of the mouth; and other structures. The mucosa is generally a nonkeratinized stratified squamous EPITHELIUM covering muscle, bone, or glands but can show varying degree of keratinization at specific locations.

D002464 Cell Migration Inhibition Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated LEUKOCYTES or MACROPHAGES. Specific CELL MIGRATION ASSAYS have been developed to estimate levels of migration inhibitory factors, immune reactivity against tumor-associated antigens, and immunosuppressive effects of infectious microorganisms.
