How do corticosteroids act?
Corticosteroids modify the functions of epidermal and dermal cells and of leukocytes participating in proliferative and inflammatory skin diseases. After passage through the cell membrane corticosteroids react with receptor proteins in the cytoplasm to form a steroid-receptor complex.

Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones.
How do corticosteroids work in the brain?
Besides acting in the brain to regulate various behaviours, corticosteroids fine-tune the subsequent pattern (amplitude and duration) of corticosteroid secretion; they activate their cognate receptors in the pituitary, hypothalamus and hippocampus and bed nucleus of the stria terminalis (BNST, a relay between the …
What does cortisone do in your brain?
During stress, the body increases production of cortisol, which prevents inflammation. Extended exposure to cortisol, or the manufactured corticosteroid, hydrocortisone, is known to reduce the size of the brain’s hippocampus, which plays a critical role in memory.
How is corticosteroid produced?
The corticosteroids are synthesized from cholesterol within the adrenal cortex. Most steroidogenic reactions are catalysed by enzymes of the cytochrome P450 family. They are located within the mitochondria and require adrenodoxin as a cofactor (except 21-hydroxylase and 17α-hydroxylase).
What is a corticosteroid?
Naturally occurring corticosteroids, hydrocortisone (Cortef) and cortisone, are produced by the outer portion of the adrenal gland known as the cortex (hence the name, corticosteroid). Corticosteroids are classified as either:
