     View Summary

    Glycans found on receptor tyrosine kinases (RTKs) have emerged as promising targets for cancer chemotherapy, aiming to address issues such as drug resistance. However, to effectively select the target glycans, it is crucial to define the structure and function of candidate glycans in advance. Through mass spectrometric analysis, this study presents a "glycoform atlas" of epidermal growth factor receptor 2 (ErbB2), an RTK targeted for the treatment of ErbB2-positive cancers. Our analysis provides an in-depth and site-specific glycosylation profile, including both asparagine- and serine/threonine-linked glycosylation. Molecular dynamics simulations of N-glycosylated ErbB2 incorporating the identified glycan structures suggested that the N-glycan at N124 on the long flexible loop in the N-terminal region plays a role in stabilizing the ErbB2 structure. Based on the model structures obtained from the simulations, analysis employing an ErbB2 mutant deficient in N-glycosylation at N124 exhibited a significantly shorter intracellular half-life and suppressed autophosphorylation compared to wild-type ErbB2. Moreover, a structural comparison between the N-glycosylated forms of ErbB2 and its structurally homologous receptor, epidermal growth factor receptor (EGFR), demonstrated distinct variations in the distribution and density of N-glycans across these two molecules. These findings provide valuable insights into the structural and functional implications of ErbB2 glycosylation and will contribute to facilitating the establishment of glycan-targeted therapeutic strategies for ErbB2-positive cancers.

     View Summary

    N-glycosylation and proper processing of N-glycans are required for the function of membrane proteins including cell surface receptors. Fibroblast growth factor receptor (FGFR) is involved in a wide variety of biological processes including embryonic development, osteogenesis, angiogenesis, and cell proliferation. Human FGFR3 contains six potential N-glycosylation sites, however, the roles of glycosylation have not been elucidated. The site-specific profiles of N-glycans of the FGFR3 extracellular domain expressed and secreted by CHO-K1 cells were examined, and glycan occupancies and structures of four sites were determined. The results indicated that most sites were fully occupied by glycans, and the dominant populations were the complex type. By examining single N-glycan deletion mutants of FGFR3, it was found that N262Q mutation significantly increased the population with oligomannose-type N-glycans, which was localized in the endoplasmic reticulum. Protein stability assay suggested that fraction with oligomannose-type N-glycans in the N262Q mutant is more stable than those in the wild type and other mutants. Furthermore, it was found that ligand-independent phosphorylation was significantly upregulated in N262Q mutants with complex type N-glycans. The findings suggest that N-glycans on N262 of FGFR3 affect the intracellular localization and phosphorylation status of the receptor.

     View Summary

    Pulmonary alveolar microlithiasis is an autosomal recessive lung disease caused by a deficiency in the pulmonary epithelial Npt2b sodium-phosphate co-transporter that results in accumulation of phosphate and formation of hydroxyapatite microliths in the alveolar space. The single cell transcriptomic analysis of a pulmonary alveolar microlithiasis lung explant showing a robust osteoclast gene signature in alveolar monocytes and the finding that calcium phosphate microliths contain a rich protein and lipid matrix that includes bone resorbing osteoclast enzymes and other proteins suggested a role for osteoclast-like cells in the host response to microliths. While investigating the mechanisms of microlith clearance, we found that Npt2b modulates pulmonary phosphate homeostasis through effects on alternative phosphate transporter activity and alveolar osteoprotegerin, and that microliths induce osteoclast formation and activation in a receptor activator of nuclear factor-κB ligand and dietary phosphate dependent manner. This work reveals that Npt2b and pulmonary osteoclast-like cells play key roles in pulmonary homeostasis and suggest potential new therapeutic targets for the treatment of lung disease.

    UNLABELLED: The pathophysiology of silicosis is poorly understood, limiting development of therapies for those who have been exposed to the respirable particle. We explored the mechanisms of silica-induced pulmonary fibrosis in a mouse model using multiple modalities including wholelung single-nucleus RNA sequencing. These analyses revealed that in addition to pulmonary inflammation and fibrosis, intratracheal silica challenge induced osteoclast-like differentiation of alveolar macrophages and recruited monocytes, driven by induction of the osteoclastogenic cytokine, receptor activator of nuclear factor-κB ligand (RANKL) in pulmonary lymphocytes and alveolar type II cells. Furthermore, anti-RANKL monoclonal antibody treatment suppressed silica-induced osteoclast-like differentiation in the lung and attenuated silica-induced pulmonary fibrosis. We conclude that silica induces osteoclast-like differentiation of distinct recruited and tissue resident monocyte populations, leading to progressive lung injury, likely due to sustained elaboration of bone resorbing proteases and hydrochloric acid. Interrupting osteoclast-like differentiation may therefore constitute a promising avenue for moderating lung damage in silicosis. ONE SENTENCE SUMMARY: Silica induces the alveolar epithelium to reprogram recruited and resident pulmonary myeloid cells to become osteoclasts that contribute to pulmonary fibrosis.

    ErbBファミリーは、EGFR、ErbB2、ErbB3、ErbB4の4つの分子からなる増殖因子受容体ファミリーである。いずれもがんの発症・進展に深く関与していると考えられている。研究代表者はこれまでにEGFRとErbB3の糖鎖解析を行い、特定の糖鎖構造が機能に関係している可能性を見出した。本研究では、ErbB4の部位特異的糖鎖構造解析を行い、糖鎖によるシグナル制御機構を明らかにすることを目的とする。令和3年度の研究では、以下の結果が得られた。 1)ErbB4の部位特異的糖鎖付加率および糖鎖構造:CHOK1細胞で発現させたErbB4細胞外ドメインを精製し、LC-ESI-MS/MSを用いて11か所の糖鎖付加部位における糖鎖付加率と糖鎖構造を解析した。N113、N333、N523の3か所はほぼ100%の糖鎖付加率を示した。また、N113、N228、N523の3か所は高マンノース型糖鎖、それ以外の8か所は複合型糖鎖が付加することがわかった。N333上の糖鎖は、他の複合型糖鎖と比較してフコース付加が少ないという特徴がみられた。 2)ErbB4の機能に重要な糖鎖の同定:CHOK1細胞を用いてErbBの野生型および糖鎖欠損変異体の安定発現細胞を樹立した。ヘレグリン刺激に対するシグナルを比較する予定である。 3)ErbB4細胞外ドメインの糖鎖欠損変異体の性質の評価:ErbB4の細胞外ドメインの野生型および糖鎖欠損変異体の大量調製を行った。ErbB4の細胞外ドメインはEGFシグナルとヘレグリンシグナルの両方を抑制することを確認した。野生型と糖鎖欠損変異体の比較を行う予定である。

    肺炎の治療においては、適切な抗菌薬に加え、過剰な炎症を制御し急性呼吸急迫症候群 (ARDS) への移行を防ぐ補助療法が重要であるが、確立されたものはない。破骨細胞は骨吸収を担う多核巨細胞であり、破骨細胞分化誘導因子(RANKL)によって単球・マクロファージ系前駆細胞から分化する。申請者は最近、珪肺モデルマウスの肺内でRANKLが産生され、結果として破骨細胞様の多核巨細胞 (肺破骨細胞とする) が誘導されることを発見した。また、抗RANKL抗体を珪肺モデルマウスに投与すると、肺破骨細胞への分化を阻害されるだけでなく、急性炎症が抑制された。本研究では、「RANKLが単球・マクロファージ系前駆細胞を肺胞マクロファージではなく、肺破骨細胞へ分化誘導することで、肺炎を重症化させている」という仮説のもと、RANKLの阻害により肺胞マクロファージへの分化を促し、病原体のクリアランス向上や抗炎症につなげるという新しい肺炎治療を提唱することを目指す。 これまでに予備実験として作製した肺ヒストプラズマ症モデルマウスの肺内において、破骨細胞分化誘導因子(RANKL)の発現が増加していることを明らかにした。さらにその結果として、破骨細胞様の多核巨細胞が肺胞腔内に出現することを確認した。
