What is thymulin?

Thymulin is a hormone produced by a gland called the thymus, which is located in the chest area in humans and other animals. It is also known as thymic factor or serum thymic factor. Thymulin is involved in the regulation of the immune system and is important for the development and maturation of T cells, a type of white blood cell that plays a crucial role in the immune response. It stimulates cellular immunity, enhances T-cell differentiation, and modulates immune function. Thymulin levels can decrease with age, leading to a decline in immune function and an increased risk of infection and disease. Thymulin may have potential therapeutic applications for autoimmune disorders and immunodeficiencies.
