Autoantibodies against triosephosphate isomerase. A possible clue to pathogenesis of hemolytic anemia in infectious mononucleosis
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...

| Sumario: | 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. |
