Mechanistic description

HBOT increases mTORC1 inhibition, promoting TFEB nuclear translocation and enhancing autophagy flux to clear pathological proteins. However, autophagy markers are easily misinterpreted (increased LC3-II can mean blocked flux), and the direction of autophagy regulation by oxygen is context-dependent. Rigorous flux validation with insoluble Aβ/tau clearance endpoints is required.

Mechanism / pathway

  1. TFEB (TFE2)
  2. neurodegeneration

Evidence for (3)

  • TFEB overexpression reduces Aβ and tau pathology

    PMID:31167123

  • mTOR inhibition improves cognitive function in AD models

    PMID:29327743

  • HBOT enhanced autophagic flux in hypoxic neuronal cultures

    PMID:28327691

Evidence against (2)

  • Increased LC3-II can mean blocked flux, not enhanced clearance

    PMID:N/A

  • Lysosomal dysfunction in AD is distal to TFEB alone

    PMID:N/A
