Prevalence of Interleukin-1 Gene Polymorphisms in Patients with Periodontitis and Healthy Subjects from the Japanese Population.

Abstract

歯周病の病因において, 重要な役割を演じているインターロイキン1 (IL-1) の遺伝子として, IL-1 A, IL-1B, IL-1RNが同定されている。IL-1A遺伝子では, -889位に, IL-1B遺伝子では+3953位と-511位に一塩基変換の多型が認められている。本研究の目的は, 日本人における成人性 (AP) および早期発症型歯周炎 (EOP) 患者, 健常者のIL-1遺伝子の多型の分布を調べ, IL-1遺伝子型の歯周病のリスクマーカーとしての有用性を検討することである。AP患者30名, EOP患者24名, 健常者30名を対象にした。IL-1の遺伝子型はrestriction fragmentlength polymorphism-polymerase chain reaction methodにより決定した。また, 末梢血単核球を分離し, リボ多糖とともに培養後, 培養上清中のIL-1β のレベルをELISA法で測定した。その結果, IL-1A-889アリル2の遺伝子型を持つ頻度は健常者群 (15.4%) と比べ, 歯周病患者群で高い傾向があり, EOP患者群では (43.5%), 統計学的に有意に高かった。ILIA-889, IL-1B+3953ともにアリル2の遺伝子型, コンポジット遺伝子型を持つ頻度は健常者群 (3.8%) と比べ歯周病患者群で高い傾向があり, EOP患者群 (34.8%) では統計学的に有意に高かった。単核球のIL-1β の産生量とIL-1遺伝子型との関係は認められなかった。本研究によりIL-1の遺伝子型は日本人における早期発症型歯周炎を含む歯周病のリスクマーカーとして, 有用であることが示唆された。
