Key Findings
- Thymus removal raises total kallikrein activity and lowers kininogen levels in rat plasma
- Injecting thymalin into thymectomized rats normalizes kallikrein activity and kininogen levels
- Thymalin appears to modulate the blood kallikrein‑kinin system in this animal model
Practical Outcomes
- Thymalin may help balance inflammation‑related pathways, but the evidence is limited to rats without a thymus and provides no human dosing guidance. For biohackers, it’s an early hint of possible immune or vascular benefits, not a ready‑to‑use protocol.
Summary
In rats without a thymus, the blood’s kallikrein‑kinin system gets over‑active, which could affect inflammation and blood pressure. Giving them the peptide thymalin brings the system back to normal levels, suggesting the peptide can regulate this pathway after thymus loss.
Abstract
The effects of thymus ablation and injection of thymalin on the blood plasma kallikrein-kinin system were studied. Thymus ablation was followed by activation of kinin formation, evidenced by an elevation of the total kallikrein activity and drop of the kininogen level. Injection of thymalin into thymectomized animals makes the characteristics under study return to normal.
