Mechanistic description

Neuroprotective compounds conjugated to specific glycan structures would selectively accumulate in tau-containing vesicles, providing targeted delivery of therapeutic agents. This Trojan horse approach exploits the unique glycan signatures as delivery addresses.

Mechanism / pathway

  1. ST6GAL1
  2. neurodegeneration

Evidence for (2)

  • Latent trait modeling of tau neuropathology in progressive supranuclear palsy.

    PMID:33635380 2021 Acta Neuropathol

  • Differences in CD75s- and iso-CD75s-ganglioside content and altered mRNA expression of sialyltransferases ST6GAL1 and ST3GAL6 in human hepatocellular carcinomas and nontumoral liver tissues.

    PMID:21147760 2011 Glycobiology

Evidence against (2)

  • Disease-associated glycans on cell surface proteins.

    PMID:27131428 2016 Mol Aspects Med

  • Disrupted glycosylation of lipids and proteins is a cause of neurodegeneration.

    PMID:31724708 2020 Brain
