摘要:

系统铁平衡受铁调素控制,这是一种肝脏激素,通过促进靶细胞的铁输出蛋白降解来限制铁流到血液中。铁依赖性铁调素诱导需要铁调素调节蛋白(HJV)的存在;HJV是一种骨形成蛋白(BMP)的共受体,在幼年型血色病中被破坏,导致明显的铁调素缺乏和组织铁过负荷。Hjv-/-小鼠可再现血色素沉着病的表型特征,但在脂多糖(LPS)处理后会出现钝性铁调素诱导。

研究人员发现Hjv-/-小鼠不能对LPS、脂肽FSL1或大肠杆菌感染诱导的急性炎症产生适合的低铁反应,因为残余的铁调素不足以彻底降低巨噬细胞的铁蛋白水平。Hfe-/-小鼠,一种轻度血色素沉着病的模型,表现出近似野生型小鼠的炎性铁调素表达和相关作用,而Hjv-/-Hfe-/-小鼠则表现为单Hjv-/-小鼠的表型。

在原代小鼠肝细胞中,Hjv缺陷不影响IL-6/Stat,只轻微抑制肝调素的BMP2/Smad信号;但其严重破坏BMP6/Sma信号,进而影响与IL-6/Stat信号的协同作用。在缺铁的野生型小鼠中,铁调素的炎性诱导被抑制,予以富含铁食物后可恢复。

总而言之,铁调素诱导炎症需要Hjv的参与,Hjv通过维持Bmp6/Smad信号的阈值来调控急性低铁反应。Hjv或可作为炎性贫血的潜在药物靶点。

Lancet Haematology:缺铁妇女补铁方案比较研究

对于缺铁女性,将每日补充的铁剂分开服用会导致血清铁调素浓度升高影响铁吸收。研究认为,将每日的补充铁剂一次性服用,隔日1次是最优的补铁方案

Blood:Erythroferrone(ERFE)可抑制BMP5/6/7诱导的铁调素合成

中心点:Erythroferrone(ERFE)在体内外均可抑制BMP/SMAD信号。ERFE通过BMP5、BMP6和BMP7抑制铁调素诱导。摘要:铁调素降低可动员铁,促进红细胞生成,但铁过量是β-地中海贫血的致病机制。促红细胞生成素(EPO)可通过增加有核红细胞来增强ERFE合成,而ERFE可抑制肝脏铁调素合成,其潜在机制尚不明确。肝脏的BMP/SMAD信号通路对于铁调素的调控至关重要,Joao

Blood:敲除BMP6可恶化HJV缺陷小鼠的表型,并降低铁调素在LPS刺激后所能达到的水平。

小鼠缺乏BMP6或其共受体铁调素调节蛋白(HJV)均可导致雄鼠铁调素不足、肝脏铁负荷以及肝外铁累积的相似表型。这一点与HJV在肝脏是BMP6的共受体的观点相一致。

Crit Care Med:外科重症监护患者铁调素和贫血!

由此可见,入住ICU时铁调素血清浓度明显增加,并在ICU停留期间(28天)显著降低。降低的铁调素浓度与增加的网织红细胞反应和通过减少IL-6和C反应蛋白浓度来体现减弱的炎症反应有关,但与贫血痊愈无关。

Blood:ERFE,一种新发现的激素,在红细胞生成过程中的作用。

ERFE是有核红细胞受促红细胞生成素刺激后分泌的一种糖蛋白类激素,可抑制铁调素的表达,从而增加铁的吸收和动员。

Blood:抑免蛋白FKBP12通过结合BMP1型受体ALK2抑制铁调素的表达。

在铁、炎症和药物的刺激下,经过BMP-SMAD通路,以及抑制mTOR与抑免蛋白FKBP12复合的雷帕霉素,激活了调节铁平衡的肝调素的关键调控的表达。FKBP12与BMP1型受体相互作用,避免不受控制的信号。通过药理学和基因研究,研究人员发现FKBP12具有调节铁调素的功能。在体外和小鼠肝脏细胞中,通过雷帕霉素或者他克莫司封闭FKBP12均可激活铁调素。
