Key Findings
- Thymosin‑alpha‑1 and its hybrid proteins increased specific immunity against Yersinia pestis in animal models
- The hybrid protein T‑TNF‑T gave the strongest and most consistent vaccine‑enhancing effect
- Recombinant thymosin‑alpha‑1 aided immune recovery after sub‑lethal gamma‑radiation in mice
Practical Outcomes
- For biohackers, the data suggest thymosin‑alpha‑1 may act as an immune‑boosting adjuvant, but the evidence is limited to animal studies. No human dosing or safety info is provided, so it’s not ready for direct self‑experimentation. If you’re interested, wait for clinical trials before adding it to a protocol.
Summary
In mice and guinea‑pig experiments, giving thymosin‑alpha‑1 or hybrid proteins that combine it with tumor‑necrosis‑factor boosted the immune response to a plague vaccine and helped recover immune function after radiation exposure.
Abstract
The influence of the preparation of chemical thymosin alpha 1 (T), recombinant thymosin alpha 1 (rT), tumor necrosis factor (TNF) and hybrid proteins on their basis (T-TNF, TNF-T and T-TNF-T) on the effectiveness of immunization against Y.pestis have been studied. The preparations of T and hybrid proteins exhibit immunostimulating action, enhancing specific immunity when injected at different periods of the vaccinal process against Y.pestis virulent strain 231 in experiments on mice and guinea pigs. The highest effectiveness and reproducibility of results is observed after the use of hybrid protein T-TNF-T. An increase in immunity after the use of the preparations of hybrid proteins is accompanied by the activation of its T-cell element. The influence of rT on the restoration of the immune system of white mice after their exposure to sublethal doses of gamma radiation has been shown.
