    Besides the activation of extracellular matrix element and cytoskeletal scaffoldings, flow (shear stress) and pressure (myogenic tone)-dependent mechanotransduction involves neuro-hormonal systems. Among these local mediators, the renin-angiotensin and purinergic systems are more specifically in the scope of the laboratory.

    We have demonstrated the role of a balance between angiotensin II type 1 receptor (AT1R) and type 2 receptor (AT2R) in the regulation of flow mediated dilation (FMD) (Daniel Henrion). AT1R stimulation reduces FMD, especially in hypertension whereas AT2R stimulation induces dilation. Nevertheless, in aging, hypertension and diabetes AT2R stimulation induces contraction. This alteration is, at least in part, associated with a vascular inflammatory response. Indeed, in diabetic rats we have shown that ThromboxaneA2 produced by COX2 reduces AT2R-mediated dilation. We currently investigate the role of inflammation in AT2R-dependent tone using models of chronic microvascular inflammation induced by anti-phospholipid antibodies (Cristina Belizna). Antiphospholipid syndrome is characterized by a recurrence of clinical events despite anticoagulation, and new therapies with anti-inflammatory effect or AT2R dependent could have a potential interest in this disease.

    Regarding purinergic receptors (Gilles Kauffenstein), we recently found that mice deficient for the major vascular extracellular nucleotides metabolizing enzyme (CD39/NTPDase1) present an exacerbated myogenic tone suggesting a participation of released nucleotides by vascular smooth muscle cells. The endothelium also is known to release large amounts of ATP in response to shear. Although the modalities of this release are not fully understood, the synergistic effect of ATP on intracellular calcium mobilization is evident. We hypothesize that the modulation of nucleotide P2 receptors participates in an autocrine mode in the cellular processes leading to acute and chronic adaptation of resistance arteries to mechanical straints. Using pharmacological approach and gene targeted animals, we focus our research on the identification of nucleotides release modalities and P2 receptors involved.
