Outline of Final Research Achievements

Surfactant protein D (SP-D) produced in the gall bladder (GB) regulated gut microbiota by its anti-microbial activity against a group of bacteria including Lactobacillus murinus. In SP-D-deficient mice which has dysbiosis in the gut, IL-22-producing cells such as gdT and NKp46 cells and CD4+ lymphoid tissue-inducers were decreased, leading to high sensitivity to colitis. In sclerosing cholangitis model mice in which SP-D was genetically depleted, the diseases was not affected. However, it is worthy of addressing the effects of SP-D on other GB or bile duct diseases including cancer and infection.

Academic Significance and Societal Importance of the Research Achievements

SP-Dは、肺胞上皮細胞から分泌される抗菌ペプチドとして肺感染防御機構に貢献していることが知られていたが、本研究により、SP-Dが肺以外にも胆嚢から産生され、腸内細菌を制御し、腸管粘膜のIL-22産生細胞の維持を介して腸管恒常性に貢献している可能性があるという新しい概念を生んだ。線維性胆管炎に対してSP-D欠損による腸内ディスバイオーシスの影響は認めなかったが、感染症やがんなどの他の胆のう疾患に対する影響を検討する価値は十分にある。何らかの影響が認められれば、炎症性腸疾患のみならず、胆嚢疾患に関してSP-Dを標的とした治療基盤を創出する可能性を持つ。
