Concept 29: What is the name of hormone that regulates immune system?

Thymosin is a hormone that plays an important role in regulating the immune system. It is produced by the thymus gland, which is located in the chest behind the sternum. Thymosin helps to stimulate the production and maturation of T-cells, which are a type of white blood cell that plays a critical role in the immune system's defense against infection and disease. T-cells are important in identifying and attacking foreign substances such as viruses, bacteria, and cancer cells. Thymosin also helps to regulate the activity of other immune cells, including B-cells and natural killer cells. Overall, thymosin plays a critical role in the development and function of the immune system.

In addition, there are several other hormones that play a role in regulating the immune system. One of the most important hormones is called cortisol, which is produced by the adrenal glands in response to stress. Cortisol can suppress the immune system by reducing the number and activity of immune cells, which helps to prevent inflammation and tissue damage in response to stress. However, chronically high levels of cortisol due to ongoing stress can weaken the immune system, making it more vulnerable to infections and disease.

Another hormone that plays a role in regulating the immune system is called prolactin. Prolactin is produced by the pituitary gland and helps to stimulate the production of immune cells called lymphocytes. It also helps to regulate the activity of immune cells by promoting the production of antibodies and enhancing the ability of immune cells to destroy invading pathogens.

Other hormones that play a role in regulating the immune system include growth hormone, which stimulates the growth and development of immune cells, and thyroid hormones, which help to regulate immune function by influencing the production and activity of immune cells.
