Outline of Final Research Achievements

In this study, we investigated the precise roles of STAT1 and neuropeptide signaling through NK2R, a receptor of neurokinin A, in inflammatory bowel disease (IBD) involving with inflammation and immune responses by using a dextran sulfate sodium (DSS)-induced colitis model and in vitro experiments. We found that NK2R expression levels of macrophages and dendritic cells were augmented by type-1 IFN stimulations and involved in the inflammation and immune responses in a STAT-1-dependent manner. Next, we revealed that STAT1-mediated induction of a chemokine and its receptor were related to disease state of DSS-induced colitis model. Furthermore, we confirmed STAT1 activation and NK2R expression in lesion and inflammation areas of patients with IBD such as ulcerative colitis and Crohn’s diseases. Based on these findings we speculate that regulation of STAT1 and neuropeptide signaling and the downstream molecules may be a promising strategy in the development of effective therapy for IBD.

Academic Significance and Societal Importance of the Research Achievements

先進国・日本において潰瘍性大腸炎、クローン病などの難治性・慢性炎症性腸疾患が年々増加している。抗炎症・免疫抑制剤により患者のQOLが以前よりは改善されたものの、病態の改善・治療のための基礎・臨床研究は依然として重要である。本研究は、病態の重篤化の新たな要因を見出したことに意義がある。今後、STAT1の活性とその下流標的分子の制御が難治性炎症性腸疾患の治療法としてさらに精査されることが望まれる。単一の治療法で強い効果が得られなくても、治療法の選択肢が増えれば、併用による相乗効果等も期待される。
