Stress induced release of ACTH from the pituitary gland
O has no affect on the immune stem
O causes release of cortisol from the adrenal gland which suppresses the immune system
• leads to feser
O increases the immune response
O activates all the non-specific defense systems
O causes an increase in white blood cell production and activation.
The stress-induced release of ACTH from the pituitary gland can have several effects on the immune system. One important effect is that it causes the release of cortisol from the adrenal gland. Cortisol is a hormone that has suppressive effects on the immune system.
When cortisol is released, it can suppress the activity of immune cells, such as T cells and B cells. This can lead to a decrease in the immune response. Additionally, cortisol can inhibit the production of certain immune molecules, such as cytokines, which are important for coordinating immune responses.
On the other hand, stress can also lead to an increase in the immune response. This is because stress triggers the release of various stress-related molecules, such as adrenaline and noradrenaline, which can activate certain nonspecific defense systems of the immune system. These defense systems include the activation of phagocytes, which are white blood cells that can engulf and destroy pathogens.
In summary, stress-induced release of ACTH from the pituitary gland causes the release of cortisol from the adrenal gland, which can suppress the immune system. However, stress can also activate certain nonspecific defense systems of the immune system, leading to an increased immune response.
