摘要

镰状细胞病(SCD)是一种遗传性血液学疾病,其代谢失调的机制尚不清楚,这是疾病进展的背后。SCD诱导溶血和氧化应激,增加用于合成谷胱甘肽的半胱氨酸的消耗。在极端氧化应激条件下,或当内源性半胱氨酸还原生成半胱氨酸受到限制或消耗时,转硫(TSS)途径被激活,作为半胱氨酸合成谷胱甘肽的替代来源。TSS通路在肝脏和大脑中活跃;然而,它在其他组织中的功能,特别是在红细胞生成过程中,却知之甚少。《通讯生物学》上的一项研究使用SCD红母细胞和转基因SCD小鼠研究了在发生溶血或缺氧条件下血液亚产物血红素过量时TSS通路的调节。结果表明,在半胱氨酸可用性受限或血红素暴露过量的情况下,TSS通路在维持半胱氨酸水平方面具有重要作用。用富马酸二甲酯治疗,在小鼠中显示出抗炎作用,增加细胞谷胱甘肽水平,使其成为未来治疗SCD的潜在药物。原文献:Xi, C.等。Commun。生物学报,8,15 (2025)
