Abstract

Resident adrenal mast cells have been shown to activate aldosterone secretion in rat and man. Especially, mast cell proliferation has been observed in adrenal tissues from patients with aldosterone-producing adrenocortical adenoma. In the present study, we show that the activity of adrenal mast cells is stimulated by low-sodium diet and correlates with aldosterone synthesis in C57BL/6 and BALB/c mice. We have also investigated the regulation of aldosterone secretion in mast cell–deficient C57BL/6 Kit W-sh/W-sh mice in comparison with wild-type C57BL/6 mice. Kit W-sh/W-sh mice submitted to normal sodium diet had basal plasma aldosterone levels similar to those observed in wild-type animals. Conversely, low-sodium diet unexpectedly induced an exaggerated aldosterone response, which seemed to result from an increase in adrenal renin and angiotensin type 1 receptor expression. Severe hyperaldosteronism was associated with an increase in systolic blood pressure and marked hypokalemia, which favored polyuria. Adrenal renin and angiotensin type 1 receptor overexpression may represent a compensatory mechanism aimed at activating aldosterone production in the absence of mast cells. Finally, C57BL/6 Kit W-sh/W-sh mice represent an unexpected animal model of primary aldosteronism, which has the particularity to be triggered by sodium restriction.

Abstract

International audience; Primary aldosteronism is the most common form of secondary hypertension with hypokalemia and suppressed renin-angiotensin system caused by autonomous aldosterone production. Our aim was to compare zona glomerulosa (ZG) structure and function between control adrenals and the peritumoral tissue from patients operated on for aldosterone-producing adenoma. ZG morphology and CYP11B1, CYP11B2, and disabled 2 expression were studied in 15 control adrenals and 25 adrenals with aldosterone-producing adenoma. A transcriptome analysis was done using publicly available data sets. In control adrenals, ZG was discontinuous, and CYP11B2 expression was focal or partly continuous and localized to 3 structures, foci, megafoci, and aldosterone-producing cell clusters. CYP11B2 expression was restricted to a limited number of ZG cells expressing Dab2 but not CYP11B1; aldosterone-producing cell clusters were composed of cells with an intermediate phenotype expressing CYP11B2 but not disabled 2 or CYP11B1. In peritumoral tissue, large remodeling of the adrenal cortex was observed with increased nodulation and decreased vascularization that were not correlated with CYP11B2 expression. In 17 out of 25 adrenals, hyperplasia of adjacent ZG was observed with persistent expression of CYP11B2 that was extended to the entire ZG. In all of the adrenals from patients with aldosterone-producing adenoma, CYP11B2 expression was present in foci, megafoci, and aldosterone-producing cell clusters. Transcriptome profiling indicates a close relationship between peritumoral and control adrenal cortex. In conclusion, adrenal cortex remodeling, reduced vascularization, and ZG hyperplasia are major features of adrenals with aldosterone-producing adenoma. Transcriptional phenotyping is not in favor of this being an intermediate step toward the formation of aldosterone-producing adenoma.
