Pathophysiological roles of ALDO/MR in novel target tissues
Working Group 5
Key outcomes will be to characterize the novel roles for aldosterone and MR activation in these non-classical tissue targets as well as to identify potentially new therapeutic indications prone to MR antagonism.
A new exciting area of MR biology began with the identification of MR expression in different target tissues, such as lung airway epithelia , eyes and skin, brain, cardiomyocytes, vasculature, macrophages/monocytes, erythrocytes and adipose tissue. This particular distribution of MR in such a wide range of tissues has suggested novel and unexpected roles for MR under different physiological and pathophysiological contexts, ranging from metabolic syndrome and oxidative stress to choroid retinopathy and stress adaptability.
The goal of WG5 is to gain deeper insights in the pathophysiological roles of MR activation in “non classical” targets of aldosterone, focusing particularly on adipose tissue, brain, eye (choroid vessels) and blood cells (leukocytes and erythrocytes). WP5 has 3 main aims:
- Understand the pathophysiological role of aldosterone and MR in ‘non-classical targets” and their potential implications in disease states. Interactions with the other WGs will be essential to achieve this goal since an integrated approach will be required. For example, consequences of hyperaldosteronism on these targets, interactions between these novel targets and the cardiovascular or renal systems or the role of the microvasculature will be important to be analyzed.
- Identify new signaling pathways of MR in novel target tissues, taking advantage of different
- expertise and animal models available in the COST network, which should accelerate scientific progress in each research group.
- Facilitating the exchange of researchers (senior scientists and students) to promote the sharing of different expertise in different scientific areas, from neuroscience, metabolism, fish biology, oxidative stress and inflammation. This should help the acquisition of diverse scientific approaches, potentially revealing novel unexpected applications in each research settings.
- Propose novel potential applications of MR antagonists in diverse clinical settings, where the use of MR blockers or modulators has not yet been explored. This will favor translational and clinical studies in WG6
