In sera from patients with acute EBV, infection and the clinical symptoms of infectious mononucleosis antibodies of the Ig class M were found that are directed against two cellular proteins. The molecular mass of these proteins was determined to be 29 (p29) and 26 kD (p26), respectively, in SDS-PAGE. P29 was identified as part of the glycolytic enzyme triosephosphate isomerase (TPI) by comparison of the NH2-terminal amino acid sequences. A purified antibody against TPI induces a 51Cr release from human erythrocytes. Possibly, anti-TPI causes hemolysis, which is an infrequent but serious symptom of infectious mononucleosis.
在急性EBV感染患者的血清中,发现了IgM类抗体,这些抗体针对两种细胞蛋白,同时伴有传染性单核细胞增多症的临床症状。在SDS-PAGE中,这些蛋白质的分子量分别确定为29kD(p29)和26kD(p26)。通过比较NH2末端氨基酸序列,p29被鉴定为糖酵解酶磷酸丙糖异构酶(TPI)的一部分。一种纯化的抗TPI抗体可诱导人红细胞释放51Cr。抗TPI可能导致溶血,这是传染性单核细胞增多症中一种罕见但严重的症状。
