684 Benefits of mineralocorticoid receptor antagonism in cutaneous wound healing

Cutaneous wound healing

Chemokines in cutaneous wound healing.

Healing of wounds is one of the most complex biological events after birth as a result of the interplay of different tissue structures and a large number of resident and infiltrating cell types. The latter are mainly constituted by leukocyte subsets (neutrophils, macrophages, mast cells, and lymphocytes), which sequentially infiltrate the wound site and serve as immunological effector cells but...

Mineralocorticoid receptor antagonism in experimental atherosclerosis.

BACKGROUND Aldosterone has been implicated in the effects of angiotensin II in the vasculature. We hypothesized that there is local expression of the mineralocorticoid receptor (MR) in the vasculature and that the use of a selective aldosterone receptor antagonist (SARA) improves endothelial function in early atherosclerosis. METHODS AND RESULTS New Zealand rabbits were placed on normal chow ...

Antagonism in the human mineralocorticoid receptor.

Key residues of the human mineralocorticoid receptor (hMR) involved in the recognition of agonist and antagonist ligands were identified by alanine-scanning mutagenesis based on a homology model of the hMR ligand-binding domain. They were tested for their transactivation capacity and ability to bind agonists (aldosterone, cortisol) and antagonists (progesterone, RU26752). The three-dimensional ...

Androgen receptor-mediated inhibition of cutaneous wound healing.

Impaired wound healing states in the elderly lead to substantial morbidity, mortality, and a cost to the US Health Services of over $9 billion per annum. In addition to intrinsic aging per se causing delayed healing, studies have suggested marked sex-differences in wound repair. We report that castration of male mice results in a striking acceleration of local cutaneous wound healing, and is as...
