About

Fifteen million people around the world suffer a stroke every year and less that 15% will ever be able to return back to normal life. The group's goal is to generate scientific knowledge of the pathophysiology of neurovascular disorders and stroke; cerebral iron dysregulation in the ischemic or hemorrhagic stroke; and multimodal imaging of the pathophysiological hallmarks of the ischemic or haemorrhagic stroke. This knowledge will enable the development of healthcare innovations in the fields of therapy, stratification/classification/predictive biomarkers, and machine/deep learning neurobehavioral assessment. These innovations are tested in proof of concept in vitro/in silico or in in vivo preclinical models of stroke.

The Cellular and Molecular Neurobiology (CMN) Research Group promotes an ecosystem of interdisciplinary collaborations to generate new ideas addressed to protecting the brain against stroke. These products of a CMN-developed first-in-class new generation of therapeutic approaches for stroke patients are under development to reduce mortality and provide a better quality of life for survivors.

Keywords: Stroke, ischemic stroke, haemorrhagic stroke, mechanisms of neurodegeneration, treatments, ferroptosis, transferrin, machine/deep learning assessment of behaviour, animal models of stroke.

    Dr Teresa Gasull holds a Master’s degree in Neuroscience and a PhD in Biology. She was appointed a Ramón y Cajal position at CSIC, and since 2006 she leads the Cellular and Molecular Neurobiology (CMN) Research Group at Germans Trias i Pujol Research Institute (IGTP). Her research on stroke has a strong translational focus to generate scientific knowledge of neurovascular disorders, cerebral iron dysregulation in stroke, and multimodal imaging of the pathophysiological hallmarks of ischemic or hemorrhagic stroke. The research done at the CMN Research Group using proof-of-concept in vivo preclinical models of stroke in rodents and in big mammals (pigs) has been applied to the development of healthcare innovations in the fields of therapy, biomarkers of stratification, classification and prediction, and machine/deep learning neurobehavioral assessment.

    Dr Gasull is a member of the Spanish Thematic Network of Stroke Research RICORS STROKE, which has more than 100 associated scientists, and of the AGAUR Group of Research in Neurosciences at IGTP. She has been awarded in the innovation programs Bioemprendedor XXI and CaixaImpulse and has received funding as PI for 13 competitive research projects and agreements with companies in the pharmaceutical/biotechnology field. Dr Gasull has published 50 articles and is author of two patents in the field of stroke. She is topic editor for Cells, guest editor for IJMS/ Curr. Issues Mol. Biol., and member of the external commitee of the IGTP/HUGTP Biobank.

Apotransferrin shows promise as an early treatment for stroke

Researchers from IGTP have discovered that administering human apotransferrin to mice models affected by intracerebral haemorrhage can mitigate the damaging effects of this severe type of stroke. This finding highlights the promising role of apotransferrin as a pre-hospital and pre-triage frontline treatment for all stroke patients. The study has been published in the journal Antioxidants.

New reproducible and minimally invasive stroke model through an endovascular approach

Researchers of the Cellular and Molecular Neurobiology (CMN) Research Group at the IGTP have developed and established a novel, reproducible and minimally invasive stroke model in pigs through an endovascular approach. The work has been conducted at the Centre for Comparative Medicine and Bioimage (CMCiB), a centre devoted to translational medicine at the very core of the Can Ruti Campus in Badalona together with the IGTP and the Germans Trias i Pujol University Hospital.
