The group GE-06 “Pathophysiology of renal and vascular damage” is an Emerging Group of the IMIBIC. Our group is composed of clinical and basic researches working together to improve the knowledge of these pathologies and to translate the basic research into the clinical practice. We integrate into our studies experts in specific areas such as Immunology, Pathology, Pharmacology, Cardiology, and Nephrology to carry out several multidisciplinary research projects. The group is led by Juan Antonio Moreno, a Ramón y Cajal tenure track researcher associated with the Department of Cell Biology, Physiology and Immunology (University of Cordoba) since 2019 (103 articles published, cumulative IF: 340; H-index: 30).
Renal and cardiovascular diseases constitute major health problems, with elevated mortality and morbidity rates. Our group is unraveling novel pathogenic mechanisms involved in the development of these diseases. Our primary goal is to understand the basis for alterations in renal and vascular wall to identify new molecules involved in the progression of these pathologies that may be used as potential diagnostic/prognosis biomarkers and to develop novel therapeutic approaches and their eventual clinical translation. Specifically, we are interested in certain cellular and molecular aspects (oxidation, inflammation, apoptosis, fibrosis, transcription factors, intracellular signaling, cytokines, etc.) involved in the progression of a number of pathologies (atherothrombosis, diabetic nephropathy, glomerular diseases, acute renal injury, nephrotoxicity, renal fibrosis, among others). To achieve these objectives, our group has applied a varied set of cellular and molecular biology techniques (flow cytometry, confocal microscopy, activity assays, gene/protein expression analysis, etc) in suitable cultured cells, experimental animal models and human samples.
We have recently observed that one of the mechanisms involved in the loss of renal function is the massive accumulation of hemoglobin (Hb), myoglobin, and other heme-related proteins. Massive accumulation of hemoprotein in the kidney promotes acute kidney injury and chronic kidney disease, as observed in patients suffering from glomerular macroscopic hematuria and massive/recurrent intravascular hemolysis (atypical hemolytic uremic syndrome, paroxysmal nocturnal hemoglobinuria and sickle cell disease). A similar pathogenic role of hemoproteins has been demonstrated during the progression of hemorrhagic atherosclerotic plaques. Our group discovered new cellular targets for the adverse effects of hemoproteins (hemoglobin (Hb), myoglobin, and other heme-related proteins) in the kidney and the atherosclerotic plaque. Thus, we identified hemoproteins-mediated injury in macrophages, tubular cells, and podocytes.
We actively collaborate with numerous researchers working in national and international centers (Fundacion Jimenez Diaz, Autonoma University Madrid, Complutense University Madrid, Odense University Hospital, Denmark, Karolinska Institute, Sweden, Paris Diderot School of Medicine, France and University of Debrecen, Hungary, among others). In addition, we are an active member of the National Network on Cardiovascular Diseases (CIBERCV), Spanish Society of Atherosclerosis, Spanish Society of Nephrology (GLOSEN), and the Immunonephrology Working Group of the European Renal Association.
In the last years, we have obtained competitive research projects supported by the National Institute of Health Carlos III (ISCIII), Spanish Society of Atherosclerosis, Spanish Society of Nephrology, Iñigo Alvarez de Toledo Renal Foundation, and the IMIBIC-Roche grant, as well as different projects funded by international biotechnological companies.
