[A comparative evaluation of the content of T-lymphocyte subpopulations, alpha 1-thymosin and autoantibodies to epithelial thymic cells in the personnel in the 30-kilometer control zone of the accident at the Chernobyl Atomic Electric Power Station].

Key Findings
- Reduced CD5+ CD8+ T‑cell counts in workers exposed to the Chernobyl zone
- Serum thymosin‑alpha‑1 levels dropped the longer the workers stayed in the contaminated area
- Autoantibodies against thymic epithelial cells rose after several years of exposure
Practical Outcomes
- The findings highlight that chronic radiation stress can suppress natural thymosin‑alpha‑1, but they offer no actionable protocol for supplementation or dosing. For biohackers, the study is mainly a warning about environmental stress rather than a guide to improve longevity or performance with this peptide.
Summary
The study looked at people who worked near Chernobyl and found that long‑term exposure was linked to lower levels of the immune‑modulating peptide thymosin‑alpha‑1 and changes in T‑cell numbers, but it doesn’t give any guidance on how to use or dose the peptide for health benefits.
Abstract
A significant decrease in mean number of CD5+, CD8(+)-lymphocytes in persons, who worked in 30-km zone of Chernobyl nuclear power station was revealed. A significant increase in percent of CD5+, CD4(+)-cell percents was observed in workers, who worked for 1,2-2,5 years in zone, but absolute number, were decreased comparing a control and data received in people, who have just arrived to work in 30-km zone. The positive correlation exists between the percent of lymphocytes and years of service in 30-km zone. The lower level of alpha 1-thymosine was revealed in serum of the persons, who worked in zone for 4.5-5 years than data received in people, who worked for 0.5 year. Increase level of serum autoantibodies reacting with thymic epithelial cell was detected in men, who worked in zone for 3-3.5 years. In persons, who worked more 5 years and have just arrived in zone identical data were received.
