靶點詳情

  • 最新研究進展：
    HP (Haptoglobin)是一種血液中的酸性糖蛋白，主要與游離血紅蛋白結合并防止游離血紅蛋白引起的氧化應激。最新研究表明，HP在免疫調(diào)節(jié)、炎癥反應和腫瘤生長等方面也起到了重要作用。HP的水平在某些腫瘤中顯著升高，與腫瘤的預后和治療效果有關。此外，一些研究還發(fā)現(xiàn)，HP可以通過調(diào)節(jié)腸道微生物群落的平衡來影響人體代謝和健康。
  • 功能：
    As a result of hemolysis, hemoglobin is found to accumulate in the kidney and is secreted in the urine. Haptoglobin captures, and combines with free plasma hemoglobin to allow hepatic recycling of heme iron and to prevent kidney damage. Haptoglobin also acts as an antioxidant, has antibacterial activity, and plays a role in modulating many aspects of the acute phase response. Hemoglobin/haptoglobin complexes are rapidly cleared by the macrophage CD163 scavenger receptor expressed on the surface of liver Kupfer cells through an endocytic lysosomal degradation pathway.; The uncleaved form of allele alpha-2 (2-2), known as zonulin, plays a role in intestinal permeability, allowing intercellular tight junction disassembly, and controlling the equilibrium between tolerance and immunity to non-self antigens.
