OSK Partial Reprogramming Under Chronic Infection¶
Linked theories: Pathogen Control (Lidsky), Epigenetic Information (Sinclair)
Hypothesis¶
Partial reprogramming improves healthspan; under chronic infection, it incurs infection tradeoffs unless pathogen control co-improves.
Design¶
- Model: Aged C57BL/6J (20 months).
 - Infection: Chronic low-virulence pathogen model (ABSL-2).
 - Arms (N=40/arm): Vehicle; OSK regimen; Antiviral/Vaccine; OSK+Antiviral.
 - Dosing: OSK weekly cycles (1w on/2w off) per tolerability pilot; doxycycline-controlled.
 
Endpoints¶
- Hazard, maximum lifespan, infection burden, tumor incidence, epigenetic age.
 
Time & Cost (est.)¶
- 12–18 months; $450k–$900k.
 
Discriminator¶
- PC: OSK alone shows infection penalty or limited hazard gain vs combined arm.
 - Sinclair: OSK extends lifespan without infection penalty under challenge.
