Abstract
The studies of prions and prion disease usually need many special platforms and techniques that differ from those for classical microbes. Search of new biomarkers and establishment of new methods for the diagnosis of human prion diseases are priorities in the field of prion study.

The Levels of Tau Isoforms Containing Exon-2 and Exon-10 Segments Increased in the Cerebrospinal Fluids of the Patients with Sporadic Creutzfeldt-Jakob Disease. Mol Neurobiol 2015; 53:3999-4009. [PMID: 26188647 DOI: 10.1007/s12035-015-9348-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2015] [Accepted: 07/07/2015] [Indexed: 10/23/2022]
Abstract
The alteration of protein tau in the cerebrospinal fluid (CSF) of Creutzfeldt-Jakob disease (CJD) has been widely evaluated, possessing a significant diagnostic value for CJD. With the biotin-labeled tau-exon-specific mAbs, direct ELISA methods were established and the levels of tau isoforms containing exon-2 and exon-10 segments in CSF of the patients with various human prion diseases and in brain tissues of scrapie-infected animals were evaluated. The results showed that the levels of tau, especially containing four repeats in microtubule binding domain, were increased in the CSF samples of the patients with sporadic CJD (sCJD). Using the unlabeled (cold) mixed exon-specific mAbs, a competitive tau ELISA was conducted based on a commercial tau kit. It revealed that the majority of the increased tau in the CSF of sCJD cases was derived from the tau isoforms with exon-2 and exon-10 segments. Increases of CSF tau isoforms with exon-2 and exon-10 segments were also observed in the patients of E200K and T188K genetic CJD (gCJD), but not in the cases of fatal familiar insomnia (FFI). The increasing levels of tau isoforms with exon-2 and exon-10 segments in the group of sCJD correlated well with the positive 14-3-3 in CSF. Additionally, the similar alterative profiles of tau isoforms with exon-2 and exon-10 segments were also observed in the brain tissues of scrapie-infected rodents and a sCJD patient. Our data here propose the tau isoforms with exon-2 and exon-10 segments increase in CSF of sCJD and some types of gCJD, which may help to understand the physiological metabolism and pathological significance of various tau isoforms in the pathogenesis of prion diseases.
