Thymulin, also known as Serum Thymic Factor or FTS, is a peptide hormone produced by the thymus, functioning by stimulating T-cell differentiation and activity. Interest in Thymulin started around the discovery of its crucial role in the immune system, particularly its influence on immune cell regulation. Early research focused on its potential to modulate immune responses, distinguishing it as a key player in immune system development. It is also being studied for its effects on neuroendocrine functions. Today, it is primarily studied for its effects on:
- Enhancing immune function
- Modulating neuroendocrine activity
- Influencing T-cell differentiation
- Regulating inflammatory responses
Thymulin's role in the immune system highlights its potential in therapeutic research.
