Dr. Mar Hernández-Guillamon has dedicated her career to the study of cerebral amyloid angiopathy (CAA) and other pathologies associated with the deposition of amyloid-beta (Abeta). In 2013, she was awarded by Carlos III Spanish Health Institute with the Miguel Servet contract to establish the Cerebral Amyloidosis line of research at VHIR. Her group has positioned in forefront of the Abeta-pathologies field, studying the molecular mechanisms involved in the Abeta transport and metabolism using in vitro and in vivo models. Her lab has also dedicated to the clinical research and discovery of biomarkers associated with CAA and other cerebrovascular diseases. The translational research developed by Dr. Hernandez-Guillamon's group has allowed the achievement of important aims to date, as demonstrated by the scientific production obtained (h-index= 35, 80 publications, >3700 citations) and the continuous leadership of national and international projects.
Research lines L5 Cerebral Amyloid Angiopathy Current project: Involment of proteolytic systems in the progression of Cerebral Amyloid Angiopathy Cerebral amyloid angiopathy (CAA) is produced by the accumulation of ß-amyloid protein within the meningeal and brain vessels. It is the second leading cause of cerebral hemorrhages. However, nowadays, factors related to brain bleedings following amyloid deposition are largely unknown. The understanding of the mollecular mechanisms that lead to cerebral hemorrhage may be the basis for future treatments. Previous evidences of our group have shown that Matrix Metal•loproteinases (MMPs) are related to brain bleeding. Now, we aim to investigate the relationship between these proteolytic systems and the appearance of intracraneal hemorrages in CAA. Our study includes: 1) The identification of both tissue and plasma biomarkers for the diagnosis and prognosis of CAA-related hemorrhages. 2) The search of the genetic markers related to proteolytic systems that could determine the risk of suffering a recurrence in CAA. We are studying a cohort of probable CAA patients that have been recruited in Hospital Vall d’Hebron in collaboration with the Stroke Project of the Cerebrovascular Diseases Study Group (Spanish Society of Neurology). 3) The study of MMPs role in ß-amyloid stimulated vascular cells in vitro. Cultured cells of the neurovascular unit are challenged with different ß-amyloid peptides and the implication of MMPs in ß-amyloid cleavage and cell toxicity are studied using cellular and molecular biology methodology. For this purpose, we use the human cerebral endothelial cell line hCMEC/D3, primary cultures of human leptomeningeal smooth muscle cells and rat/mouse glial and neuronal cultures.
