在溶血过程中,噬红细胞处理受损的红细胞。这阻止了血红蛋白的细胞外释放,使血红素解毒,并在相关的代谢途径中使铁还原。作为这一过程的补充,结合珠蛋白和血红素结合蛋白将红细胞毒素血红蛋白和血红素运送到细胞清除。病理性溶血在多种疾病中超过巨噬细胞的能力和清道夫的合成。这种失衡导致血红蛋白驱动的疾病进展。为了满足治疗选择的空白,基于清道夫蛋白的治疗剂正在临床开发中。
During hemolysis, erythrophagocytes dispose damaged red blood cells. This prevents the extracellular release of hemoglobin, detoxifies heme, and recycles iron in a linked metabolic pathway. Complementary to this process, haptoglobin and hemopexin scavenge and shuttle the red blood cell toxins hemoglobin and heme to cellular clearance. Pathological hemolysis outpaces macrophage capacity and scavenger synthesis across a diversity of diseases. This imbalance leads to hemoglobin-driven disease progression. To meet a void in treatment options, scavenger protein-based therapeutics are in clinical development.
