NCT04928534

Brief Summary

In this study, high-throughput screening and multi-omics (transcriptomics and proteomics) joint analysis technology will be employed to explore potential CTE/TES biomarkers (RNA and protein) in blood and its exosomes. Thereafter, these biomarkers will be combined with the reported TBI biomarkers to create a novel set of CTE/TES molecular diagnostic signatures. The findings may open a new avenue for the clinical diagnosis of the disease and the future research on its therapeutic strategy.

Outcome Measures

Primary Outcomes (2)

  • Blood level of novel protein biomarkers for CTE/TES

    Novel protein biomarkers for CTE/TES will be screened out by transcriptomics + proteomics high-throughput detection and multi-omics bioinformatics analysis. Their levels will be further verified using ELISA assay.

    Baseline

  • Blood level of novel RNA biomarkers for CTE/TES

    Novel RNA biomarkers for CTE/TES will be screened out by transcriptomics + proteomics high-throughput detection and multi-omics bioinformatics analysis. Their levels will be further verified using RT-PCR.

    Baseline

Secondary Outcomes (7)

  • Blood level of classical biomarkers for CTE/TES

    Baseline

  • Ultrasound examination of the carotid arteries and lower limb arteries

    5 years post-enrollment

  • Serum Treg cell count and degree of senescence

    5 years post-enrollment

  • Cognitive function tests - RPQ-3

    5 years post-enrollment

  • Cognitive function tests - RPQ-16

    5 years post-enrollment

  • +2 more secondary outcomes
