The Scientific Foundation of Thymalin

Molecular Composition and Active Components

Thymalin is a polypeptide complex isolated from the thymus of calves, containing a mixture of biologically active short peptides . Through advanced analytical techniques including mass spectrometry and high-performance liquid chromatography (HPLC), researchers have identified several key active components within the thymalin complex:

EW Dipeptide (Thymogen): A dipeptide with immunomodulatory properties that reduces angiotensin-induced vasoconstriction and preserves endothelium-dependent vascular relaxation . EW stimulates cellular immunity and nonspecific resistance in organisms, exerting an activating effect on macrophages, blood lymphocytes, thymocytes, and neutrophils .
KE Dipeptide (Vilon): A dipeptide that stimulates cellular immunity and nonspecific resistance, with activating effects on macrophages, blood lymphocytes, thymocytes, and neutrophils . KE induces the expression of CD4 and CD5 molecules on thymus cells, stimulating their differentiation in the direction of T helpers .
EDP Tripeptide (Crystagen): A tripeptide that promotes heterochromatinization of chromatin in blood lymphocytes and demonstrates biological activity in immune regulation .

Mechanism of Action: Epigenetic Regulation of Gene Expression

Thymalin and its active components operate through sophisticated molecular mechanisms that have been elucidated through extensive research. These short peptides are able to penetrate into the cell nucleus and nucleolus, where they can complementary bind to specific DNA sequences and/or histone proteins . This binding results in epigenetic regulation of gene expression and synthesis of proteins involved in immune function, inflammation, and cellular ageing.

DNA Binding Properties: Using molecular docking studies, researchers have identified preferred DNA sequences for thymalin’s active components. GGAG was found to be the optimal double-stranded DNA sequence in the classical B-form for binding the EW dipeptide, while GCGC is the preferred dsDNA sequence in the curved nucleosomal form for the KE dipeptide .

Gene Expression Regulation: Thymalin and its constituent peptides regulate the expression of numerous genes involved in:

Immune system function and cytokine production
Heat-shock protein synthesis
Fibrinolysis system components
Gerontogenes (ageing-related genes)
Cell differentiation, proliferation, and apoptosis pathways

Cytokine Modulation: In vitro models of inflammatory reactions have demonstrated that thymalin and its EW and KE dipeptides reduce the synthesis of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α in human peripheral blood mononuclear cells by 1.4–6.0 times . This immunomodulatory effect is based on the potential ability of its active components to regulate protein synthesis involved in the development of cytokine storms .

Key Research Applications

Immunology and T-Cell Differentiation Research: Thymalin is extensively used in studies investigating immune system function, T-lymphocyte development, and cellular immunity. Research demonstrates that thymalin normalizes the functions of the immune system and stimulates the processes of regeneration and hematopoiesis when they are suppressed . The immunoprotective effect of thymalin is expressed in the restoration of the number and ratio of T and B lymphocytes, their subpopulations, an increase in their functional activity, and increased phagocytosis .

In studies on human hematopoietic blood stem cells (HSC), thymalin decreased the expression of CD44 on HSC 2.8-fold . CD44 is a ligand for E- and L-selectin that maintains the HSC subpopulation and is involved in the activation of proliferation and enhancement of HSC survivability. Thymalin reduced the expression of CD117 on HSC 2.2-fold . CD117 is a receptor for stem cell growth factor that stimulates proliferation and early stages of differentiation. Notably, thymalin reduced the expression of CD28 on HSC 6.9-fold . CD28 is expressed on CD4+ and CD8+ lymphocytes and is involved in the activation of mature T cells.

Gerontology and Cellular Ageing Research: Thymalin has demonstrated significant geroprotective properties in animal experiments and clinical studies. The drug contributes to the restoration of functions of the immune system and reduced mortality in elderly patients . The use of thymalin helped to reduce the incidence of acute respiratory diseases in elderly and senile people by 2.0–2.4 times .

In organotypic cultures of spleen tissue from young and old rats, thymalin and its short peptides increased the growth zone index of spleen explants by 20–50%, stimulated cell proliferation, and reduced apoptosis by 29–42% compared to controls . The KE peptide normalizes the telomere length of PHA-stimulated blood lymphocytes in people of different ages . KE also regulates the gene expression of IGF1, FOXO1, TERT, TNKS2, and NFκB in human embryonic mesenchymal stem cells during their replicative and stationary aging .

Infectious Disease Research: Thymalin is effective in research models of various infectious diseases including hepatitis A and B, erysipelas, meningococcal infection, typhoid fever, acute respiratory diseases, pneumonia of various origins, and cavernous pulmonary tuberculosis . The drug has been studied for its potential in complex therapy for viral infections, including COVID-19 research .

In a prospective, randomized single-blind controlled clinical trial involving older patients with severe COVID-19, patients administered thymalin against the background of standard therapy manifested more rapid clinical improvement, higher proportions of recovery from lymphopenia, faster normalization of the concentration of C-reactive protein, D-dimer, the number of lymphocytes and NK-cells in the blood, compared to patients who received standard therapy only . Thymalin halved hospital mortality in older patients with severe COVID-19 .

Regeneration and Tissue Repair Research: Thymalin is used in studies investigating regeneration normalization and the depression of hematogenesis after chemical and radiotherapy . The drug has shown effectiveness in the treatment of patients with acute lung abscesses, leading to a decrease in the systemic inflammatory response syndrome, a decrease in plasma fibrinolytic activity, and the cessation of hypercoagulation .

Hematopoiesis Research: Thymalin stimulates the processes of regeneration and hematopoiesis when they are suppressed, making it valuable for research into bone marrow function and blood cell development following chemotherapy or radiation therapy models .

Respiratory System Research: Thymalin accumulates in epithelial cells of the human respiratory tract during early embryogenesis . The drug has been studied in patients with pneumonia of various etiologies and viral infectious diseases, where its use was accompanied by normalization of blood coagulation and fibrinolytic activity .
