Summary This project will assess the vascular reactivity of aortic vessels exposed to the uraemic toxin IS and its inhibition using selective AhR antagonists in aortic rings. Following experiments the tissue will be examined using immunohistochemistry and real time PCR.
Cardiovascular disease in the setting of chronic kidney disease (CKD) displays unique characteristics, primarily left ventricular (LV) hypertrophy with extensive interstitial fibrosis as well as endothelial dysfunction, arterial stiffness, calcification and inflammation, collectively termed ‘uraemic cardiomyopathy’. Uraemic toxins are elevated in the circulation of patients with CKD. Indoxyl sulphate (IS) is one such uraemic toxin that has been extensively examined in cells and animal models of disease. IS has been demonstrated to exert deleterious effects in cardiac, renal, vascular and immune cells, and in tissues from man and animal models. Recently an intracellular receptor for IS was identified, the aryl hydrocarbon receptor (AhR), which, when activated, mediates numerous biological processes including inflammation, vascular remodeling, and atherosclerosis. This project will assess the vascular reactivity of aortic vessels exposed to the uraemic toxin IS and its inhibition using selective AhR antagonists in aortic rings. Following experiments the tissue will be examined using immunohistochemistry and real time PCR. This project will potentially identify a novel agent to treat vascular and inflammatory changes in patients’ with CKD.
