A researcher from Biovendor at our lab

Tereza Mráčková, is a junior researcher who works at BioVendor – Laboratorní Medicína a.s. BioVendor LM is an internationally active biotechnology company with its own research, development and manufacturing and international sales and marketing network. It has specialized in the development of original immunoassay kits for the detection of novel hormone-like proteins and protein biomarkers as well as related antibodies and recombinant proteins. Recently they are also focusing on novel topics known to be of great interest among the scientific and diagnostic community – microRNA biomarkers, liquid biopsy, exosome isolation, and immunodiagnostic multiplexing and automation.

Tereza is also a PhD student in  the Stroke Program at the International Clinical Research Center (St. Anne’s University Hospital BRNO).

She is spending some days at our laboratory to test some miRNAs that could be connected to stroke diagnosis and prognosis.

 

 

 

Paper published at STEM CELLS

The Neurovascular Research Laboratory has published a new article  in collaboration with researchers of the Neuroprotection Research laboratory at Massachusetts General Hospital showing how Endothelial progenitor cells might participate in rescue from oxygen‐glucose deprivation by transferring mitochondria particles to damaged brain endothelial cells.

The investigation has been published at Stem Cells and one of the paper figures has illustrated the cover of the September’s issue.

These findings suggest that EPCs may support brain endothelial energetics, barrier integrity and angiogenic function partly through extracellular mitochondrial transfer, and support their potential use in stroke repair.

Three LIN members had defended their thesis work

On June 8, 11 and 12, three members of the laboratory defended their thesis work.

Alba Simats, member of the Biomarkers line, defended her work entitled:

Therapeutic potential of new biomarkers of cerebral ischemia

Sofía Fernández de Retana, member of the Amyloid line, presented the work:

Effect of variations on recombinant ApoA-I and ApoJ as a therapeutic approach in the context of brain Beta-amyloidosis

Marina Gabriel, member of the Neurorepair line, defended the work entitled:

Modulation of neurorepair markers in rehabilitation therapies after stroke and in a pre-clinical model of cerebral ischemia

First LIN retreat

 

 

On January 22nd, the neurovascular research laboratory held its first Retreat.

It has been an opportunity, especially for people who have recently joined the group, to learn a little about our history and the main lines of research.

We have had the collaboration of a gamification expert who has organised  games and quizzes focused on knowing each other. We have also put in common the objectives to achieve in 2018 and what we believe we can improve.

Title: New MAGnetic Biomaterials for Brain Repair and Imaging after Stroke (MAGBBRIS)

According to the World Health Organization, 15 million persons suffer a stroke worldwide each year, and neuro-repair treatments could offer the opportunity to treat stroke patients by extending the therapeutic time window.

By engineering novel magnetic nano-biomaterials we will achieve tissue repair in the context of an ischemic event. We will take advantage of nanotechnology to deliver therapeutic growth factors, secreted by progenitor cells, into the injured brain. MAGBBRIS will demonstrate that growth factors, secreted by endothelial progenitor cells, with proved potential to induce tissue repair, can be encapsulated in magnetic biomaterials and be successfully and safely transplanted into mouse brains with the guidance of magnetic fields, to induce tissue repair.

MAGBBRIS consortium is made up by highly multidisciplinary materials-science, biomedical and clinical research with industrial partnership. The project will provide a new medicinal product ready to be tested in a preclinical multicentric study.

New H2020 project: PRESTIGE AF

New H2020 project : PRESTIGE AF

PREvention of STroke in Intracerebral hemorrhaGE survivors with Atrial Fibrillation

Intracerebral hemorrhage (ICH) is a severe stroke subtype causing higher mortality and more disability than other strokes. 20% of ICH survivors have atrial fibrillation (AF), a major cause of ischemic stroke (IS). While IS in AF patients is generally prevented by oral anticoagulants (OAC), their use in ICH survivors is uncertain due to increased bleeding risk. No evidence from randomized controlled trials (RCT) is available addressing this dilemma. Personalized risk prediction is desirable to balance benefits of OAC against bleeding risk for individualized prevention.
Objectives: (1) To perform the first sufficiently powered RCT in ICH survivors with AF testing if direct OAC are superior for IS prevention and non-inferior regarding ICH recurrence versus antiplatelet or no antithrombotic therapy (2) To personalize antithrombotic prevention by multidimensional risk modeling (3) To estimate population impact of trial outputs on health economic consequences and generalizability to European population (4) To explore patient-centered aspects including
adherence, attitudes towards antithrombotic therapy and gender imbalances in trial enrollment.

PRESTIGE-AF addresses the unmet need of best antithrombotic stroke prevention in ICH patients with AF. Recurrent stroke reduces individual life expectancy, quality of life and has high public health impact. Work packages integrating biological data will generate new tools to tailor prevention. Modeling of economic and societal consequences and replication in real-life settings will estimate population impact.
