Adrenocorticotropic hormone (ACTH; also adrenocorticotropin, corticotropin) is a polypeptide tropic hormone produced by and secreted by the anterior pituitary gland. [1] It is also used as a medication and diagnostic agent .
Corticotropes produce and release ACTH, a 39 amino acid peptide hormone, in response to corticotropic releasing hormone (CRH) release from the hypothalamus. CRH is a 41-amino-acid peptide hormone that is secreted by the parvocellular neurosecretory cells , which are found within the paraventricular nucleus of the hypothalamus.
Plants lack specialized organs for the secretion of hormones, although there is spatial distribution of hormone production. For example, the hormone auxin is produced mainly at the tips of young leaves and in the shoot apical meristem. The lack of specialised glands means that the main site of hormone production can change throughout the life ...
DHEA is produced in the zona reticularis of the adrenal cortex under the control of adrenocorticotropic hormone (ACTH) and by the gonads under the control of gonadotropin-releasing hormone (GnRH). [ 39 ] [ 40 ] It is also produced in the brain. [ 41 ]
Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, including embryogenesis , [ 1 ] the regulation of organ size, pathogen defense, [ 2 ] [ 3 ] stress tolerance [ 4 ] [ 5 ] and reproductive development.

ACTH is a hormone that stimulates the adrenal gland to produce cortisol and other steroid hormones. However, the organism makes antibodies against this viral protein, and those antibodies also kill the human ACTH hormone, which leads to the suppression of adrenal gland function.
