Summary
Thymomodulin, a calf thymus extract, modulates T and B lymphocyte functions and promotes myelopoiesis with minimal toxicity. This immunomodulator maintains biological activity even when administered orally.
Area of Science:
- Immunology
- Pharmacology
Background:
- Thymomodulin is a calf thymus acid lysate containing peptides (1-10kD) with demonstrated immunomodulating activities.
- Preclinical studies indicate minimal toxicity, even at high doses, across various animal models.
Purpose of the Study:
- To investigate the immunomodulatory effects of Thymomodulin on lymphocyte maturation and function.
- To assess the impact of Thymomodulin on myelopoiesis and its potential cell lineage specificity.
Main Methods:
- In vitro and in vivo studies were conducted to evaluate Thymomodulin's effects on human and murine lymphocytes.
- Assays were performed to assess T and B lymphocyte maturation and function, as well as myelopoiesis via granulocyte-macrophage colony formation.
Main Results:
- Thymomodulin regulates the maturation of pre-T lymphocytes and modulates functions of mature T and B lymphocytes.
- The compound demonstrated the ability to promote myelopoiesis, evidenced by increased granulocyte-macrophage colonies.
- Evidence suggests Thymomodulin exhibits specificity towards T cells, with potential indirect effects on other cell lineages.
Conclusions:
- Thymomodulin is a biologically active immunomodulator with significant effects on T cell maturation and function.
- Its ability to promote myelopoiesis and maintain oral bioavailability makes it a promising therapeutic agent.
