Key Findings
- Thymalin enhances the formation of specific microbial allergy in guinea pigs
- It increases the proportion of T‑ and B‑lymphocytes in immune organs
- Multiple injections produce a stronger effect than a single injection
- Thymalin itself can trigger allergic reactions
Practical Outcomes
- For self‑experimenters, thymalin may act as a potent immune stimulant but also raises the risk of heightened allergic reactions, especially with repeated dosing. Use with caution, start at low single doses, and monitor for any new sensitivities before considering higher or repeated regimens.
Summary
In guinea pigs, the peptide thymalin boosted the body’s allergic response to a bacterial antigen and changed the mix of immune cells, especially increasing T‑ and B‑lymphocytes. Giving several doses made the effect stronger than a single dose, and the animals could also develop an allergy to thymalin itself.
Abstract
The influence of thymalin on the formation of specific allergy and the distribution of immunocompetent cells in the immunity organs of guinea pigs immunized with Haemophilus influenzae antigen was studied. The stimulating influence of thymalin on the allergization of the body, changes in the lymphocyte subpopulations, as well as the possibility of the development of allergic reactions to thymalin, were established. Multiple injections of thymalin produced a stronger stimulating effect on the formation of specific microbial allergy and on the content of T- and B-lymphocytes than a single injection of the preparation.
