Abstract

Erosive oral lichen planus (EOLP) and recurrent aphthous stomatitis (RAS) are T-cell mediated inflammatory immune disorders. It was investigated mRNA expression pattern of several regulatory factors, such as, CD28, CD45, CD152, CD154, CD279, which influence T lymphocyte in unstimulated whole saliva (UWS) of EOLP and RAS patients. It was collected unstimulated whole saliva during 10 minute in EOLP 18 people, RAS patients 12 people, healthy control 8 people. We investigated mRNA expression of T lymphocyte regulatory factors, such as, CD28, CD45, CD152, CD154, CD279, with real time reverse transcription polymerase chain reaction. In EOLP group, CD45, CD279 expressed higher and CD154 expressed lower than control. In RAS, CD45, CD270 expressed higher and CD28, CD154 expressed lower than control. In addition CD152 salivary mRNA expression of EOLP is higher than that of RAS. The above results were suggested that the mRNA expression of T lymphocyte regulatory factors in unstimulated whole saliva of EOLP and RAS contributes to diagnosis of diseases.

미란형 구강편평태선과 재발성 아프타성 구내염은 T림프구에 의해 매개되는 염증성 면역질환이다. T림프구에 영향을 주는 다양한 조절 인자들 중 CD28, CD45, CD152, CD154, CD279등의 mRNA가 미란형 구강편평태선 및 재발성 아프타성 구내염 환자들의 비자극성 전타액내에서 어떻게 발현되는지를 살펴보고, 이것의 진단학적 가치를 평가하고자 한다. 미란형 구강편평태선으로 진단받은 환자군 18명, 재발성 아프타성 구내염으로 진단받은 환자군 12명, 정상군 8명에게서 비자극성 전타액을 10분간 채득한 후, 상피세포를 분리하여 mRNA를 추출하였다. Real time PCR을 이용하여 각 군의 T림프구 조절 인자들의 mRNA 발현 양상을 비교분석하였다. 미란형 구강편평태선의 T림프구 조절인자들의 mRNA 발현 양상은 정상인과 비교 결과, CD45, CD279는 높게 측정되었고, CD154는 낮게 측정되었다. 재발성 아프타성 구내염 환자들의 T림프구 조절인자들의 mRNA 발현 양상은 정상인과 비교 결과, CD45, CD279는 높게 발현되었고, CD28, CD154는 낮게 발현되었다. 부가적으로 미란형 구강편평태선 환자군의 타액내 CD152의 발현 양상은 재발성 아프타성 구내염 환자군보다 높게 발현되었다. 미란형 구강편평태선과 재발성 아프타성 구내염 환자들의 비자극성 전타액내 T림프구 조절인자들의 mRNA 발현 양상은 각 질환의 진단에 기여할 수 있을 것으로 사료된다.
