Project Leaders and Projects

1. Prof Hans Strijdom (MBChB, PhD): Induction of endothelial injury in a cell model of cardiac and aortic endothelial cells and investigating cellular mechanisms; establishment of a protocol to harvest and culture primary rat aortic endothelial cells from lean and obese rats for investigating underlying mechanisms; investigation into heterogeneity between cardiac microvascular and aortic endothelial cells; establishment of an ex vivo model to measure vascular endothelial function in aorta segments; the effects of anti-dyslipidaemic drugs (fenofibrate and statins) on cultured endothelial cells and isolated aortic segments; investigating the putative protective effects of rooibos and melatonin (in vivo, ex vivo and in vitro) on the cardiovascular system of rats exposed to nicotine. In 2014, Prof Strijdom received a major EU-Africa grant (ERAfrica grant of the EU 7th Framework Programme) to form an international, multi-centre research consortium, including Belgium and Austria. Prof Strijdom is the project coordinator. The study (called "EndoAfrica") will investigate the effects of HIV-infection and antiretroviral treatment on the endothelial function of populations in Cape Town, Potchefstroom and Mthatha. Prof Strijdom is also collaborating with Dr Peace Mabeta from 中国体育彩票 of Pretoria on the role of Src in an endothelial tumour cell line (endothelioma).
