Outline of Final Research Achievements

The purpose of this study was to elucidate the mechanism of pain suppression by hyperpolarization-activated cyclic nucleotide-gated channels (HCN channels) inhibitors. HCN channel inhibitors (ivabradine and ZD7288) suppressed carrageenin-induced inflammatory pain in a dose-dependent manner in rats. In addition, LPS-stimulated production of TNFα and IL-6 was suppressed in cultured mouse macrophage-like cells (RAW264.7). Thus, these results indicated that HCN channel inhibitors suppress inflammatory pain via HCN channels.

Academic Significance and Societal Importance of the Research Achievements

口腔顎顔面領域においても難治性の疼痛がみられる。既存の治療薬に対して抵抗性のある症例があり、新しい鎮痛薬の開発が期待されている。本研究で対象とした過分極活性化環状ヌクレオチド依存性チャネル阻害薬は、新しい鎮痛薬の候補として考えられている。本研究成果によって、HCNチャネル阻害薬に抗炎症作用があることが証明されたことから、術後疼痛やがん性疼痛など、炎症に伴って発生する難治性疼痛に対して有効な鎮痛薬として、開発されることが期待できる。
