    Abstract

    Background

    In Japan, six workers handling cross-linked water-soluble acrylic acid polymer (CWAAP) at a chemical plant suffered from lung diseases, including fibrosis, interstitial pneumonia, emphysema, and pneumothorax. We recently demonstrated that inhalation of CWAAP-A, one type of CWAAP, causes pulmonary disorders in rats. It is important to investigate dose–response relationships and recoverability from exposure to CWAAPs for establishing occupational health guidelines, such as setting threshold limit value for CWAAPs in the workplace.

    Methods

    Male and female F344 rats were exposed to 0.3, 1, 3, or 10 mg/m<sup>3</sup> CWAAP-A for 6 h/day, 5 days/week for 13 weeks using a whole-body inhalation exposure system. At 1 h, 4 weeks, and 13 weeks after the last exposure the rats were euthanized and blood, bronchoalveolar lavage fluid, and all tissues including lungs and mediastinal lymph nodes were collected and subjected to biological and histopathological analyses. In a second experiment, male rats were pre-treated with clodronate liposome or polymorphonuclear leukocyte-neutralizing antibody to deplete macrophages or neutrophils, respectively, and exposed to CWAAP-A for 6 h/day for 2 days.

    Results

    CWAAP-A exposure damaged only the alveoli. The lowest observed adverse effect concentration (LOAEC) was 1 mg/m<sup>3</sup> and the no observed adverse effect concentration (NOAEC) was 0.3 mg/m<sup>3</sup>. Rats of both sexes were able to recover from the tissue damage caused by 13 weeks exposure to 1 mg/m<sup>3</sup> CWAAP-A. In contrast, tissue damage caused by exposure to 3 and 10 mg/m<sup>3</sup> was irreversible due to the development of interstitial lung lesions. There was a gender difference in the recovery from CWAAP-A induced pulmonary disorders, with females recovering less than males. Finally, acute lung effects caused by CWAAP-A were significantly reduced by depletion of alveolar macrophages.

    Conclusions

    Pulmonary damage caused by inhalation exposure to CWAAP-A was dose-dependent, specific to the lung and lymph nodes, and acute lung damage was ameliorated by depleting macrophages in the lungs. CWAAP-A had both a LOAEC and a NOAEC, and tissue damage caused by exposure to 1 mg/m<sup>3</sup> CWAAP-A was reversible: recovery in female rats was less than for males. These findings indicate that concentration limits for CWAAPs in the workplace can be determined.

    <title>Abstract</title><sec>
    <title>Background</title>
    Transforming growth factor (TGF)-β is a multifunctional cytokine involved in cell differentiation, cell proliferation, and tissue homeostasis. Although TGF-β signaling is essential for maintaining blood vessel functions, little is known about the role of TGF-β in lymphatic homeostasis.


    </sec><sec>
    <title>Methods</title>
    To delineate the role of TGF-β signaling in lymphatic vessels, TβRII<sup>fl/fl</sup> mice were crossed with Prox1-Cre<sup>ERT2</sup> mice to generate TβRII<sup>fl/fl</sup>; Prox1-Cre<sup>ERT2</sup> mice. The <italic>TβRII</italic> gene in the lymphatic endothelial cells (LECs) of the conditional knockout TβRII<sup>iΔLEC</sup> mice was selectively deleted using tamoxifen. The effects of <italic>TβRII</italic> gene deletion on embryonic lymphangiogenesis, postnatal lymphatic structure and drainage function, tumor lymphangiogenesis, and lymphatic tumor metastasis were investigated.


    </sec><sec>
    <title>Results</title>
    Deficiency of LEC-specific TGF-β signaling in embryos, where lymphangiogenesis is active, caused dorsal edema with dilated lymphatic vessels at E13.5. Postnatal mice in which lymphatic vessels had already been formed displayed dilation and increased bifurcator of lymphatic vessels after tamoxifen administration. Similar dilation was also observed in tumor lymphatic vessels. The drainage of FITC-dextran, which was subcutaneously injected into the soles of the feet of the mice, was reduced in TβRII<sup>iΔLEC</sup> mice. Furthermore, Lewis lung carcinoma cells constitutively expressing GFP (LLC-GFP) transplanted into the footpads of the mice showed reduced patellar lymph node metastasis.


    </sec><sec>
    <title>Conclusion</title>
    These data suggest that TGF-β signaling in LECs maintains the structure of lymphatic vessels and lymphatic homeostasis, in addition to promoting tumor lymphatic metastasis. Therefore, suppression of TGF-β signaling in LECs might be effective in inhibiting cancer metastasis.

    Constriction of the apical plasma membrane is a hallmark of epithelial cells that underlies cell shape changes in tissue morphogenesis and maintenance of tissue integrity in homeostasis. Contractile force is exerted by a cortical actomyosin network that is anchored to the plasma membrane by the apical junctional complexes (AJC). In this study, we present evidence that MAGI proteins, structural components of AJC whose function remained unclear, regulate apical constriction of epithelial cells through the Par polarity proteins. We reveal that MAGIs are required to uniformly distribute Partitioning defective-3 (Par-3) at AJC of cells throughout the epithelial monolayer. MAGIs recruit ankyrin-repeat-, SH3-domain- and proline-rich-region-containing protein 2 (ASPP2) to AJC, which modulates Par-3-aPKC to antagonize ROCK-driven contractility. By coupling the adhesion machinery to the polarity proteins to regulate cellular contractility, we propose that MAGIs play essential and central roles in maintaining steady state intercellular tension throughout the epithelial cell sheet.

    Blood and lymphatic vessels structurally bear a strong resemblance but never share a lumen, thus maintaining their distinct functions. Although lymphatic vessels initially arise from embryonic veins, the molecular mechanism that maintains separation of these two systems has not been elucidated. Here, we show that genetic deficiency of Folliculin, a tumor suppressor, leads to misconnection of blood and lymphatic vessels in mice and humans. Absence of Folliculin results in the appearance of lymphatic-biased venous endothelial cells caused by ectopic expression of Prox1, a master transcription factor for lymphatic specification. Mechanistically, this phenotype is ascribed to nuclear translocation of the basic helix-loop-helix transcription factor Transcription Factor E3 (TFE3), binding to a regulatory element of Prox1, thereby enhancing its venous expression. Overall, these data demonstrate that Folliculin acts as a gatekeeper that maintains separation of blood and lymphatic vessels by limiting the plasticity of committed endothelial cells.

    Platelets participate in not only thrombosis and hemostasis but also other pathophysiological processes, including tumor metastasis and inflammation. However, the putative role of platelets in the development of solid organs has not yet been described. Here, we report that platelets regulate lung development through the interaction between the platelet-activation receptor, C-type lectin-like receptor-2 (Clec-2; encoded by Clec1b), and its ligand, podoplanin, a membrane protein. Clec-2 deletion in mouse platelets led to lung malformation, which caused respiratory failure and neonatal lethality. In these embryos, α-smooth muscle actin-positive alveolar duct myofibroblasts (adMYFs) were almost absent in the primary alveolar septa, which resulted in loss of alveolar elastic fibers and lung malformation. Our data suggest that the lack of adMYFs is caused by abnormal differentiation of lung mesothelial cells (luMCs), the major progenitor of adMYFs. In the developing lung, podoplanin expression is detected in alveolar epithelial cells (AECs), luMCs, and lymphatic endothelial cells (LECs). LEC-specific podoplanin knockout mice showed neonatal lethality and Clec1b-/--like lung developmental abnormalities. Notably, these Clec1b-/--like lung abnormalities were also observed after thrombocytopenia or transforming growth factor-β depletion in fetuses. We propose that the interaction between Clec-2 on platelets and podoplanin on LECs stimulates adMYF differentiation of luMCs through transforming growth factor-β signaling, thus regulating normal lung development.

    In the central nervous system, endothelial cells (ECs) and pericytes (PCs) of blood vessel walls cooperatively form a physical and chemical barrier to maintain neural homeostasis. However, in diabetic retinopathy (DR), the loss of PCs from vessel walls is assumed to cause breakdown of the blood-retina barrier (BRB) and subsequent vision-threatening vascular dysfunctions. Nonetheless, the lack of adequate DR animal models has precluded disease understanding and drug discovery. Here, by using an anti-PDGFRβ antibody, we show that transient inhibition of the PC recruitment to developing retinal vessels sustained EC-PC dissociations and BRB breakdown in adult mouse retinas, reproducing characteristic features of DR such as hyperpermeability, hypoperfusion, and neoangiogenesis. Notably, PC depletion directly induced inflammatory responses in ECs and perivascular infiltration of macrophages, whereby macrophage-derived VEGF and placental growth factor (PlGF) activated VEGFR1 in macrophages and VEGFR2 in ECs. Moreover, angiopoietin-2 (Angpt2) upregulation and Tie1 downregulation activated FOXO1 in PC-free ECs locally at the leaky aneurysms. This cycle of vessel damage was shut down by simultaneously blocking VEGF, PlGF, and Angpt2, thus restoring the BRB integrity. Together, our model provides new opportunities for identifying the sequential events triggered by PC deficiency, not only in DR, but also in various neurological disorders.

    リンパ節において、リンパ管を介して到達した抗原や液性因子に対する素早い応答は、リンパ洞の独特な組織構造と濾過機能に依存し、免疫・生理学的にも極めて重要な過程であると考えられる。しかし、このリンパ洞フィルターの構造や機能の詳細については未だ不明な点が多い。本研究は、リンパ節の特定領域に局在する特殊なリンパ管内皮細胞、間質ストローマ細胞、組織マクロファージにより構成されるリンパ洞フィルターの組織・細胞構造の分子基盤と構築原理、および免疫・生理学的意義の究明を目的とする。
    初年度は、野生型マウスや各種遺伝子発現レポーターマウスを用いて、リンパ節の洞内皮細胞、ストローマ細胞、マクロファージを含む免疫細胞の各種マーカーについて、共焦点および多光子励起レーザー顕微鏡による高解像度顕微観察を行い、リンパ洞フィルターの分子細胞構成・微細構造の詳細を明らかにした。また、蛍光標識デキストラン(分子量可変)、ポリスチレンビーズ(粒径可変)、黄色ブドウ球菌、酵母菌、LPS、卵白アルブミン(OVA)をマウス皮下に投与し、浸出リンパ節のリンパ洞フィルターによる捕捉・移送の経時的観察を行うとともに、フローサイトメトリーによりマクロファージサブセットへの取り込みを定量的に評価した。さらに、クロドロン酸内包リポソーム投与によるマクロファージ除去の影響を検討した。これらの解析により、髄洞の一部が網目状のリンパ管内皮細胞ネットワークと髄質マクロファージにより特殊な物理フィルター構造を形成し、リンパ節におけるリンパ液フィルターの本体であることを明確にした。我々は、この領域を辺縁髄洞接続帯(SMB)領域と名付けた。

    私達は、肺とリンパ管の発生にはリンパ管内皮の膜蛋白ポドプラニン(PDPN)と血小板活性化受容体CLEC-2の結合により活性化された血小板から放出されるTGF-βが必須であることを報告した。CLEC-2 nullマウスでは全身のリンパ節が欠損し、肺、肝臓などにリンパ球の集簇した異所性リンパ組織(ELS)が認められた。以上より私達は「胎生期に生理活性物質を満載した血小板が、CLEC-2を介して様々な細胞のPDPNに触れ、特異的な箇所で活性物質を放出して器官発生が進行する」という全身に共通の血小板による発生制御機構が存在すると考えた。本課題ではリンパ節発生をモデルとし、血小板がいつ、どこで、どのようにしてリンパ節発生を制御するかと、血小板が運ぶ生理活性物質の実態を明らかにする。
    令和2年度までに、CLEC-2下流のシグナル分子であるSyk null マウス、PDPN null マウス、リンパ管特異的 PDPN 欠損マウスには鼠経リンパ節が欠如していることを見出し、リンパ節の形成には血小板活性化とリンパ管内皮 PDPN が必要であることが示された。しかし、令和3年度にリンパ管特異的 PDPN 欠損マウスのリンパ節をさらに調べたところ、小型のリンパ節が確認される個体も存在した。文献的には、Prox1欠損マウスなど、リンパ管が欠損したマウスでも、リンパ節は認められるが、通常よりも小型と報告されている。また、リンパ節を形成するLTi, LTo細胞でのPDPNを検討するため、免疫染色を行ったところ、CD3陽性のLTi細胞の周囲を取り囲むように、PDPN陽性のLTo様細胞が認められた。以上より、リンパ管内皮PDPNは、リンパ節原基の形成には不要だが、その成熟には必要であると考えた。リンパ節の成熟には、LTo細胞のPDPNが関与するとの仮説を立てた。

    RA-GEF-1, RA-GEF-2, and phospholipase Cε? (PLCε) are specific activators (guanine nucleotide exchange factors) for Rap1, which mediate cross-talks between different species of small G proteins. We have elucidated crucial functions of RA-GEF-1 in fetal blood vessel formation and neuronal migration, of RA-GEF-2 in sperm formation, and of PLCε in inflammation and carcinogenesis through generation and phenotypic characterization of whole body and conditional knockout mice of the respective genes.
