    • The present invention relates to a biomarker for the detection of brain damage or a disease associated with loss of neurons, said biomarker comprising a protein fragment of the neurofilament heavy chain (NfH) protein in a biological sample, wherein said protein fragment is a polypeptide selected from the group consisting of i) a polypeptide having the amino acid sequence selected from the group consisting of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, and polypeptides composed of amino acids 476-1026 and 476-986 of SEQ ID NO 6; ii) a protein fragment of the NfH protein having an amino acid sequence that is at least 60% identical to SEQ ID NO:1, at least 60% identical to SEQ ID NO:2, at least 60% identical to SEQ ID NO:3, at least 60% identical to SEQ ID NO:4, at least 60% identical to SEQ ID NO:5; or at least 60% identical to a polypeptide composed of amino acids 476-1026 and.or 476-986 of SEQ ID NO 6; iii) an Enterokinase cleavage product of the NfH protein; and iv) a polypeptide that is derived from a naturally occurring allelic variant of the nucleic acid coding for NfH protein.
    • 本发明涉及用于检测脑损伤或与神经元损失有关的疾病的生物标志物,所述生物标志物包含生物样品中神经丝重链(NfH)蛋白质的蛋白质片段,其中所述蛋白质片段是选择的多肽 i)具有选自由SEQ ID NO:1,SEQ ID NO:2,SEQ ID NO:3,SEQ ID NO:4,SEQ ID NO:5组成的组的氨基酸序列的多肽, 和由SEQ ID NO 6的氨基酸476-1026和476-986组成的多肽; ii)NfH蛋白的蛋白片段,其具有与SEQ ID NO:1至少60%相同的氨基酸序列,与SEQ ID NO:2至少60%相同,与SEQ ID NO: 3,与SEQ ID NO:4至少60%相同,与SEQ ID NO:5至少60%相同; 或至少60%与由SEQ ID NO 6的氨基酸476-1026和或476-986组成的多肽相同; iii)NfH蛋白的肠激酶切割产物; 和iv)衍生自编码NfH蛋白的核酸的天然存在的等位基因变体的多肽。
