Blood:口服17R-RvD1可缓解镰刀型细胞病患者的炎症和组织损伤

2018-11-10 MedSci MedSci原创

内源性脂质介质Resolvins(Rv)在抗炎过程中发挥关键作用。镰刀型细胞病(SCD),是一种遗传性的血红蛋白病,特点是炎症和血管阻塞。研究人员建立人源化的SCD小鼠模型,观察其低氧/再灌注后的促分解事件的变化。结果发现17R-RvD1(7S,8R,17R-三羟基-4Z,9E,11E,13Z,15E,19Z-二十二碳六烯酸)在减少体外的微血管内皮细胞招募的人SCD血液白细胞和体内的白细胞黏附和转

内源性脂质介质Resolvins(Rv)在抗炎过程中发挥关键作用。镰刀型细胞病(SCD),是一种遗传性的血红蛋白病,特点是炎症和血管阻塞。研究人员建立人源化的SCD小鼠模型,观察其低氧/再灌注后的促分解事件的变化。

结果发现17R-RvD1(7S,8R,17R-三羟基-4Z,9E,11E,13Z,15E,19Z-二十二碳六烯酸)在减少体外的微血管内皮细胞招募的人SCD血液白细胞和体内的白细胞黏附和转染中发挥新型保护作用。

暴露于低氧/复氧的SCD小鼠,口服17R-RvD1可减少全身/局部炎症和肺/肾的血管功能障碍。17R-RvD1的作用机制包括:1)增强SCD红细胞和多形白细胞的增殖;2)降低NF-κB的激活;3)降低炎性细胞因子、血管激活标志物和E-选择素的表达。

总而言之,17R-RvD1或可代表一种新的治疗SCD炎性血管病变的新策略。

Blood:利用CRISPR/Cas9介导编辑β球蛋白位点可重诱导成人合成胎儿血红蛋白,从而改善镰刀型细胞病患者的细胞表型

中心点:利用CRISPR/Cas9破坏β球蛋白位点结构可重激活成年人有核红细胞的胎儿γ球蛋白表达。重激活胎儿γ球蛋白的合成和下调镰刀型β球蛋白的表达可改善镰刀型细胞病的细胞表型。摘要:β球蛋白位点的自然发生的大片段丢失常导致胎儿血红蛋白获得遗传性的持久性存活,在此条件下可减轻临床镰刀型细胞病(SCD)和β地中海贫血的严重性。近日,Blood杂志上发表一篇文献,研究人员利用CRISPR/Cas9技术

BLood:二甲双胍可治疗镰刀型细胞病!

中心点:人类原代红系祖细胞的功能研究提示FOXO3可调控γ-球蛋白合成。用二甲双胍处理人类原代红系祖细胞可部分以FOXO3依赖性方式增加其胎儿血红蛋白的合成。摘要:诱导红细胞合成胎儿血红蛋白(HbF,α2γ2)可通过减少镰刀型血红蛋白(HbS,α2βs2)的浓度抑制其聚合,从而改善镰刀型细胞病(SCD)的病理生理。羟基脲(HU),是FDA唯一批准用于SCD的药物,部分作用是诱导HbF,但并不是完全
