ABSTRACT

Background:

Treatment of dendritic cells (DC) with aldosterone induces the secretion of IL-6 and TGF-beta. The polarization of naïve T cells to helper 17 T lymphocytes with DCs pre-incubated with aldosterone, has been described in vivo, generating an IL-17 hyper-secreting phenotype, a cytokine associated with cardiac and renal fibrosis. There are mineralocorticoid receptors (MR) in immune cells and their activation may determine the inflammatory (M1) or adaptive (M2) macrophage phenotype. Aldosterone levels could regulate immunogenic gene expression in these cells, modulating the liberation of specific cytokines.

Aim:

To assess in humans the association of aldosterone levels and IL-17 with inflammatory markers in peripheral blood mononuclear cells (PBMC). Material and

Methods:

In blood samples of 176 participants aged 18 to 67 years (61 percent women) with a body mass index of 27.1 +/- 4.8 kg/m2, aldosterone, plasma renin activity (ARP), cortisol, C reactive protein, andIL-17 were measured. mRNA was isolated from PBMCs to measure the expression of MR RAC-1, HO-1, TLR-4, CD-14, NGAL and IL-17 by real time polymerase chain reaction.

Results:

Aldosterone correlated positively with ARP and the expression of CD-14 in PBMCs. Plasma levels of IL-17 were positively associated with the expression of MR, Rac1a and NGAL.

Conclusions:

Aldosterone and IL-17 levels were associated with inflammatory activation markers in PBMC, which could activate MRand promote a subclinical inflammatory status inducing hypertension.
