Adrenocortical secretion is controlled primarily by adrenocorticotropic hormone (ACTH), from the anterior pituitary (Chapter 20), but mineralocorticoid secretion is also subject to independent control by circulating factors, of which the most important is angiotensin II, a peptide formed in the bloodstream by the action of renin. Its primary function is to regulate the production and release of cortisol and other glucocorticoids from the adrenal glands, which are essential for various bodily processes. The kidneys, pancreas, and liver are not direct targets of ACTH. Its primary function is to stimulate the adrenal glands to release cortisol, a vital hormone for stress response, metabolism regulation, and immune function. These hormones travel along the axons into storage sites in the axon terminals of the posterior pituitary. The inner layer, the reticulata zone, produces sex hormones, regulated by the hypothalamic–pituitary – adrenal axis. Its biological activity resides in the sequence of its first 24 N-terminal amino acid residues, and this sequence is identical in all species that have been studied. Adrenocorticotropic hormone (ACTH) is a hormone produced by the pituitary gland that stimulates the adrenal glands to release cortisol and other steroid hormones.

Those derived from lipids include steroids (Figure 17. Adrenocorticotropic hormone exerts its role through binding to the G protein-coupled receptor, MC2R, which activates the adenylyl cyclase cascade leading to cAMP production and subsequent activation of cAMP-dependent protein kinase A (PKA). The most important hormone for the adrenal glands to operate properly is adrenocorticotropic hormone, which stimulates the release of the stress hormone cortisol from the cortex. One is the neurohypophysis, which forms as a downgrowth of the floor of the brain and gives rise to the median eminence and the neural lobe; these structures are neurohemal organs. In this Research Topic, we will discuss the various mechanisms involved in ACTH action, from ACTH binding to its receptor to steroid secretion, as well as the pathological consequences of the disruption of specific components of the pathways. They elicit specific responses by binding to receptors on or in target cells. Despite the knowledge of ACTH’s pivotal role in the endocrine stress response for nearly a century, there has never been a potent, selective ACTH receptor antagonist. Corticotrophs are cells that produce ACTH and make up 10% to 20% of the anterior lobe. [5] A G protein–coupled receptor located on the external cell plasma membrane, it is coupled to G αs and upregulates levels of cAMP by activating adenylyl cyclase.
