Thymalin
Also known as: Thymus Extract, Thymic Peptide Complex
Thymic Peptide Bioregulator | Immune Modulator
Overview
Thymalin is a natural peptide bioregulator derived from calf thymus gland, developed in the Soviet Union in the 1970s. It contains a mixture of thymic peptides that support immune restoration, anti-aging, and tissue regeneration. Research spanning decades has shown significant geroprotective effects, with studies demonstrating up to 2-fold reduction in mortality rates and 4-fold reduction when combined with Epithalamin.
Key benefits
- Potent immune system restoration and modulation
- Significant geroprotective (anti-aging) effects
- Reduced mortality rate in clinical studies (2.0-2.1 fold)
- Normalized cardiovascular, endocrine, and nervous system function
- Reduced acute respiratory disease incidence (2.0-2.4 fold)
- Enhanced T-lymphocyte differentiation (CD4+, CD8+)
- Antitumor effects in animal studies
- Safe for elderly populations with no side effects
Mechanism of action
Thymalin's immunoprotective action stems from short peptides (KE, EW, EDP) that specifically bind to double-stranded DNA and histone proteins to regulate gene expression. It stimulates differentiation and activity of T-lymphocytes, especially CD4+ and CD8+ cells, promotes cytokine regulation, enhances antigen response, and stimulates stem cell differentiation. It also affects gerontogene activity and immune system protein synthesis.
