Serum thymosin-alpha 1: lack of association between elevated levels and HIV infection.
Chen. S J SJ; Ko. H S HS
Key Findings
- Thymosin‑alpha‑1 levels were similar in HIV‑positive and HIV‑negative participants.
- Levels did not rise after six months, even in people who later developed HIV antibodies.
- Male homosexual participants had lower thymosin‑alpha‑1 levels than haemophiliac participants.
Practical Outcomes
- For biohackers, this research shows that measuring thymosin‑alpha‑1 isn’t useful for detecting or tracking HIV infection, and it offers no guidance on using the peptide for health or performance benefits.
Summary
The study looked at blood levels of the peptide thymosin‑alpha‑1 in people at risk for AIDS and found that having HIV didn’t make these levels go up, and the levels didn’t change over time. It also noticed a difference between two groups (gay men vs. haemophiliacs) but didn’t explain why.
Abstract
Serum thymosin-alpha 1 levels as detected by radioimmunoassay (RIA) have been reported to be elevated in AIDS. We studied 143 individuals in two risk groups for AIDS (male homosexuals and haemophiliacs) for serum thymosin-alpha 1 and antibodies to HIV. RIA for thymosin-alpha 1 was performed in Dr A. Goldstein's laboratory at George Washington University, Washington DC. We found that similar proportions of seropositive and seronegative subjects within each risk group showed elevated thymosin-alpha 1 levels. Retesting after 6 months did not reveal significant increments over previous levels in seropositive subjects or in those developing HIV antibodies in the repeat samples. Thus, although elevated thymosin-alpha 1 levels might be a possible serum marker for AIDS, their association with HIV infection was not demonstrated. In addition, the male homosexuals we studied showed significantly lower thymosin-alpha 1 levels than haemophiliacs but this difference remains to be explained.
