What is thymalin?
Thymalin is a peptide preparation originally isolated from calf thymus tissue. It has been studied as an immunomodulator — a substance that influences immune-system activity (Morozov & Khavinson, 1997).
What the research examined
Research on thymic peptides reports activation of T-cell differentiation and T-cell recognition, changes in intracellular signaling, and modulation of cytokine output (such as IL-2 and interferon) from blood lymphocytes. From thymalin, an immunomodulatory dipeptide (Glu-Trp) was later isolated and developed synthetically. Thymic peptides are described as participating in the regulation of inflammatory processes (Morozov & Khavinson, 1997).
How it is thought to work
The proposed role is regulation of T-cell-mediated immunity and cytokine balance, which is why thymic peptides have been studied in contexts of immune dysfunction (Morozov & Khavinson, 1997).
The limits of the current evidence
- Much of this literature is older and concentrated in specific research groups; modern controlled clinical confirmation is limited.
- Thymalin is not an approved medicine in the United States; this material is supplied for laboratory research use only.
