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.
This hypothesis posits that mild hyperbaric oxidative stress activates Nrf2-ARE transcriptional programs, upregulating SOD1, catalase, GPx1, and HO-1 without causing cumulative oxidative injury. It provides the most direct framework for parameter optimization via dose-response mapping and represents the strongest balance of mechanistic plausibility and parameter tractability. The hormetic dose-window concept directly addresses the knowledge gap about optimal HBOT parameters.
Convergent vs Divergent Predictions
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
**Overall**
These hypotheses are mechanistically plausible but overfit to generic HBOT biology. The main weakness is that they infer an “optimal” pressure, duration, and frequency from downstream path...
