  • L-arginine-induced pancreatitis aggravated by inhibiting Na<sup>+</sup>/Ca<sup>2+</sup> exchanger 1

    <p>Na<sup>+</sup>/Ca<sup>2+</sup> exchangers (NCX) are an exchange transporter of Na<sup>+</sup> and Ca<sup>2+</sup> ions on the plasma membrane. There are three types of NCX: NCX1, NCX2, and NCX3. We have been working for many years to understand the role of NCX1 and NCX2 in gastrointestinal motility. In this study, we focused on the pancreas, an organ closely related to the gastrointestinal tract, and used a mouse model of acute pancreatitis to investigate a possible role for NCX1 in the pathogenesis of pancreatitis. We characterized a model of acute pancreatitis induced by excessive doses of L-arginine. We administered the NCX1 inhibitor SEA0400 (1 mg/kg) 1 hr prior to L-arginine-induced pancreatitis and evaluated pathological changes. Mice treated with NCX1 inhibitors show exacerbation of the disease with decreased survival and increased amylase activity in response to L-arginine-induced experimental acute pancreatitis, and this exacerbation correlates with increased autophagy mediated by LC3B and p62. These results suggest that NCX1 has a role in regulating pancreatic inflammation and acinar cell homeostasis.</p>

  • Analyses of damage-associated molecular patterns, particularly biglycan, in cisplatin-induced rat progressive renal fibrosis

    NAKAGAWA Minto, IZAWA Takeshi, KUWAMURA Mitsuru, YAMATE Jyoji

    <p>Damage-associated molecular patterns (DAMPs) and their receptors (TLR-2 and -4) may play important roles in renal fibrosis, of which the pathogenesis is complicated. We used rat renal lesions induced by a single intraperitoneal injection of cisplatin at 6 mg/kg body weigh; consisting of tissue damage of renal tubules on days 1 and 3, further damage and regeneration with inflammation mainly on days 5 and 7, and interstitial fibrosis on days 9, 12, 15, and 20. Microarray analyses on days 5 (the commencement of inflammation) and 9 (the commencement of interstitial fibrosis) showed that DAMPs increased by more than two-fold relative to control included common extra-cellular matrix (ECM) components such as laminin (Lamc2) and fibronectin, and heat shock protein family, as well as fibrinogen, although it was limited analysis; Lamc2, an element of basement membrane, may be regarded as an indicator for damaged renal tubules. In the real-time RT-PCR analyses, TLR-2 significantly increased transiently on day 1, whereas TLR-4 significantly increased on days 9 and 15, almost in agreement with the increased biglycan (a small leucine-rich proteoglycan as ubiquitous ECM component). As M1/M2 macrophages participated in renal lesions, such as inflammation and fibrosis, presumably, TLR-4, which may be expressed in immune cells, could play crucial roles in the formation of renal lesions in association with biglycan.</p>

    これまでの研究に際して、ラットに鉄分を多く含む飼料(高Fe飼料)を与えると出血傾向がみられるという現象に予期せず遭遇した。本研究ではその機序を調査した。6週齢の雄性F344/DuCrlCrljマウスに、標準飼料(鉄を0.02%配合)(対照群)または高Fe飼料(1%配合)(高Fe群)を6週間与えた。各種検体を採取して分析したところ、血清中と肝組織中の鉄濃度は対照群に対し高Fe群で有意に上昇していた。同様にトランスフェリンの鉄飽和度も有意に上昇し、ほぼ飽和していた。その一方で、2種の肝トランスアミナーゼの濃度はいずれも上昇していなかった。高Fe群では血漿検体のプロトロンビン時間と活性化部分トロンボプラスチン時間は有意に延長していたが、それらは病理学的に評価した出血の有無とは関係していなかった。また高Fe群では凝固因子の第II因子と第VII因子の活性は有意に低下していたが、第VIII因子の活性は変化していなかった。血小板数には両群間で差はみられず、高Fe群の出血傾向は二次止血の障害に起因するものと示唆された。鉄を0.8%以上配合した飼料を与えられたラットでは多数の臓器に出血が観察された。本結果から、鉄の過剰負荷を受けるとビタミンK不足が不顕性に生じ、それが原因となって凝固異常への感受性が高まる可能性があることが示唆された。

    正常な肝臓と化学的に誘発した肝損傷におけるマクロファージの影響を調べるため、正常ラットとチオアセトアミド(TAA)処理ラットに、免疫抑制剤のデキサメタゾン(DX)を投与し比較した。DX(0.5または1.0mg/kg体重)を3、7、11日間反復投与した。その結果、正常肝臓のCD163陽性肝臓常在マクロファージ(Kupffer細胞)の数が減少し、AST値とALT値が上昇した。DX(0.5mg/kg BW)前処理し、TAA(300mg/kg BW)処理したラットでは、M1およびM2マクロファージの数が、TAA処理のみのラットに比べて有意に低下していた。さらにTAA注射によって誘発された肝細胞損傷からの修復性線維化は、DX前処理によって抑制された。以上より、マクロファージは正常な肝臓の恒常性維持(AST、SLTに反映)に影響を与えるだけでなく、化学的に誘発された肝臓病変発生(修復性線維化の低下)にも影響を与えると考えられた。

    CCDC85C遺伝子欠損による出血性水頭症(hhy)マウスは、脳出血を伴う非閉塞性水頭症を発症し、皮質下異所性灰白質を形成する。CCDC85C蛋白質の生物学的機能は、マウス以外の動物において未だ不明であるため、ヒトに近い表現型を示すラットを用いてCCDC85C遺伝子ノックアウト(Ccdc85c KO)ラットを作製した。作製法はTranscriptional activator-like effector nuclease(TALEN)を用いたゲノム編集により、F344ラットのCcdc85cをノックアウトした。KOラットはCcdc85cに約350bpの欠失があり、CCDC85C蛋白質の発現が欠失していた。Ccdc85c KOラットを用いて病理組織学的解析を行ったところ、非閉塞性水頭症、皮質下異所性灰白質の形成および頭蓋内出血を呈した。KOラットは、hhyマウスと類似した多くの病理学的特徴を有していた。これらの結果により、CCDC85Cはラット脳の発達に重要な役割を果たしており、大脳におけるCCDC85Cの生物的機能はラットとマウスの種間においても類似していることが示唆された。

    細胞膜の過分極によって活性化される過分極活性化環状ヌクレオチド依存性チャネル1(HCN1)は心臓や脳に多く分布し、自発性リズム形成やペースメーカーの役割を担っている。最近、HCN1欠損ラットを用いた研究により、欠神てんかんや緩やかな筋肉の緊張と異常な歩行などが観察された。そこでHCN1欠損ラットの筋力と運動機能を評価したところ、ワイヤーハングテスト、傾斜面テスト、フットプリント分析など各種行動テストの結果により、HCN1欠損ラットは運動協調障害および筋力低下を呈したが、筋電図、筋組織学および深部腱反射では正常であった。これらの結果により、HCN1チャネルは運動協調能力および筋力に寄与していることが示され、HCN1欠損ラットの筋力低下は末梢神経系ではなく中枢神経系の関与により生じることが示唆された。

    細胞膜の過分極によって活性化される過分極活性化環状ヌクレオチド依存性チャネル1(HCN1)は心臓や脳に多く分布し、自発性リズム形成やペースメーカーの役割を担っている。最近、HCN1欠損ラットを用いた研究により、欠神てんかんや緩やかな筋肉の緊張と異常な歩行などが観察された。そこでHCN1欠損ラットの筋力と運動機能を評価したところ、ワイヤーハングテスト、傾斜面テスト、フットプリント分析など各種行動テストの結果により、HCN1欠損ラットは運動協調障害および筋力低下を呈したが、筋電図、筋組織学および深部腱反射では正常であった。これらの結果により、HCN1チャネルは運動協調能力および筋力に寄与していることが示され、HCN1欠損ラットの筋力低下は末梢神経系ではなく中枢神経系の関与により生じることが示唆された。
