Synthesized by the zona fasciculata of the adrenal cortex in the adrenal glands, Cortisol is one of the important corticosteroid hormones. It is basically a stress regulating hormone secreted in times of acute stress-related problems. The role of Cortisol has been discussed extensively among the medical fraternity around the world. Glean through this article to bone up authentic information on the role of Cortisol.
Clinical studies and researches have been made to find out the role of Cortisol. These experiments are basically carried out with an objective to check out the increased plasma Cortisol levels in the pathological procedures related to autonomic failure. This syndrome generally occurs from hypoglycemia.
One of the prime areas of clinical investigation in determining the role of Cortisol involves steering of the metabolic response to a blended fluid containing epinephrine, glucagon, norepinephrine and other stress hormones including Cortisol itself. Investigations have been made on dogs, both before and after the hormone infusion. This investigation involves the insertion of a thin flexible tube into the body to permit introduction or withdrawal of fluids or to keep the passageway open. On one occasion, the dogs were kept under pathological observation for 70 hours at a stretch. The infused fluid generally contains norepinephrine, epinephrine, glucagon and Cortisol. Note that it may also be made without Cortisol.

On completion of the experiment, it was observed that the exogenous elements stepped up the the levels of arterial plasma glucagon, epinephrine, Cortisol and norepinephrine six times their normal levels. The synthesis of glucose in the body, along with gluconeogenesis and glycogenolysis, needs to be measured as well. This assessment is done using arteriovenous-difference methods and tracer. The fact that the level of Cortisol does not rise during stress hormone therapy somewhat inhibits the increase in arterial plasma glucose concentration and glucose production. The stress hormone therapy has no effect on the net output of hepatic glucose.

The function of Cortisol in relation to the normal physiological activities of the immune system is worth taking a note of. Cortisol reduces stress by inhibiting the immune system. This hormone plays an important part in foreclosing the multiplication of T-cells. Since T-cells do not react to interleukin-1, Cortisol assumes all the more relevance as far as the inhibition of T-cell growth is concerned.
The role of Cortisol with regards to bone metabolism is worth considering as well. This hormone tends to slow down bone formation, allowing for the development of osteoporosis.
