Aldosterone stimulates Na + and water reabsorption from the gut, salivary and sweat glands in exchange for K +. Aldosterone stimulates secretion of H + via the H+/ATPase in the intercalated cells of the cortical collecting tubules; Aldosterone upregulates expression of NCC in the distal convoluted tubule chronically and its activity acutely.

The name mineralocorticoid derives from early observations that these hormones were involved in the retention of sodium, a mineral.The primary endogenous mineralocorticoid is aldosterone, although a number of other endogenous hormones (including progesterone [1] and deoxycorticosterone) have mineralocorticoid function.
The immune system specifically targets the cells of the adrenal cortex and destroys them, but Addison's disease can also be caused by a severe infection such as tuberculosis. Some symptoms include hypoglycemia and decreased blood sodium levels and increased blood potassium levels caused by a deficiency of aldosterone. These electrolyte ...
The immune system is involved in many aspects of physiological regulation in the body. The immune system interacts intimately with other systems, such as the endocrine [83] [84] and the nervous [85] [86] [87] systems. The immune system also plays a crucial role in embryogenesis (development of the embryo), as well as in tissue repair and ...
5) and aldosterone (C 21 H 28 O 5) (cortisone and aldosterone are isomers). The main corticosteroids produced by the adrenal cortex are cortisol and aldosterone. [1] The etymology of the cortico-part of the name refers to the adrenal cortex, which makes these steroid hormones. Thus a corticosteroid is a "cortex steroid". [citation needed]
Aldosterone acts primarily on the distal convoluted tubules and collecting ducts of the kidneys, stimulating the excretion of potassium ions into the urine. [65] It does so, however, by activating the basolateral Na + /K + pumps of the tubular epithelial cells. These sodium/potassium exchangers pump three sodium ions out of the cell, into the ...
Upon ligand binding, the receptor undergoes conformation changes that stimulate the enzyme adenylyl cyclase, which leads to an increase in intracellular cAMP [11] and subsequent activation of protein kinase A. ACTH influences steroid hormone secretion by both rapid short-term mechanisms that take place within minutes and slower long-term actions.
There are two main categories of immunostimulants: [1] Specific immunostimulants provide antigenic specificity in immune response, such as vaccines or any antigen.; Non-specific immunostimulants act irrespective of antigenic specificity to augment immune response of other antigen or stimulate components of the immune system without antigenic specificity, such as adjuvants and non-specific ...
