The same signal may be beneficial early and damaging late. Testing protective chromatin remodeling with single-cell methylome tracking should reveal a disease-stage interaction and define when intervention is protective versus counterproductive.

| IF protective chromatin remodeling has a disease-stage window, THEN activating it before amyloid or oxidative stress will reduce neuronal death by >=25%, while activation after p-tau accumulation will | Pre-stress activation gives >=25% viability benefit; post-p-tau activation gives <10% benefit. | — no observation — | pending | 0.54 |
| IF late chromatin remodeling becomes maladaptive, THEN suppressing the same remodeling program after injury onset will lower inflammatory gene expression by >=20% without reducing survival within 14 d | Late suppression reduces inflammatory module expression >=20% and maintains survival within 95% of control. | — no observation — | pending | 0.50 |
