Outline of Research at the Start

OAの慢性疼痛への進行の機序に基づいた疾患修飾型治療にて慢性疼痛への進行を制御する新規治療法を創出する事を最終目的として、本研究は以下の3ステップで行う。
①OA慢性疼痛モデルの慢性疼痛への移行期(投与後1日目から7日目)の組織学的解析
②慢性疼痛への移行期の滑膜線維化に対する疾患特異的マクロファージの作用機序の解明
③疾患特異的マクロファージの作用機構をブロックする疾患修飾型治療の疼痛制御の検証

Outline of Final Research Achievements

Injection of 1.0 mg of monoiodoacetic acid into the knee of rats examined the cell dynamics. It was found that cell invasion and proliferation began on the 1st day after administration, and increased especially by the 5th day. Furthermore, cell proliferation occurred mainly in the superficial synovial membrane. The cells in the superficial synovial layer spread to the deep layer by being extruded by newly proliferating cells in the superficial layer. On the 5th to 7th days, the synovial cells with cell infiltration showed fibrosis, angiogenesis, and neurogenesis accompanying the blood vessels. Pain avoidance behavior by the incapacity test continued during and after this period, leading from acute inflammation to chronic pain. We consider that the simultaneous changes in cells and tissues are a phenomenon that can be said to be one of the mechanisms by which acute inflammation becomes chronic pain.

Academic Significance and Societal Importance of the Research Achievements

軟骨変性を主体とする膝変形性関節症の罹患者数は日本国内の4の内820万人以上が膝の慢性疼痛に悩んでいる。一方で、このように高い罹患率にもかかわらず,慢性疼痛発症の病態の科学的検証は不足している。そのため進行機序に基づいた疾患修飾型治療法は無い。炎症誘発物質(モノヨード酢酸)のラット膝関節内への注射は関節炎を誘発し、続いて骨軟骨破壊を起こすため、膝の慢性疼痛モデルとして知られている。インキャパスタンステストによる疼痛回避行動はこの間そして、その後へと継続しており、急性の炎症から慢性疼痛へと続いていた。同時期の細胞と組織の変化は急性の炎症が慢性疼痛へとなる機序の一旦と言える現象であると考察する。
