Extracellular vesicles enriched with an endothelial cell pro-survival microRNA ...
Fernandes, Hugo; Zonnari, Alessandra; Abreu, Ricardo Cerqueira de; Aday, Sezin; Barão, Marta; Albino, Inês; Lino, Miguel; Branco, Ana; Seabra, CátiaEndothelial cell (EC) activity is essential for tissue regeneration in several (patho)physiological contexts. However, our capacity to deliver in vivo biomolecules capable of controlling EC fate is relatively limited. Here, we screened a library of microRNA (miR) mimics and identified 25 miRs capable of enhancing the survival of ECs exposed to ischemia-mimicking conditions. In vitro, we showed that miR-425-5p, ...
Therapeutic Nanoparticles for the Different Phases of Ischemic Stroke
Bernardo-Castro, Sara; Albino, Inês; Barrera-Sandoval, Ángela María; Tomatis, Francesca; Sousa, João André; Martins, Emanuel; Simões, SusanaStroke represents the second leading cause of mortality and morbidity worldwide. Ischemic strokes are the most prevalent type of stroke, and they are characterized by a series of pathological events prompted by an arterial occlusion that leads to a heterogeneous pathophysiological response through different hemodynamic phases, namely the hyperacute, acute, subacute, and chronic phases. Stroke treatment is highl...
Engineered extracellular vesicles as brain therapeutics
Lino, Miguel M.; Simões, Susana; Tomatis, Francesca; Albino, Inês; Barrera, Angela; Vivien, Denis; Sobrino, Tomás; Ferreira, LinoExtracellular vesicles (EVs) are communication channels between different cell types in the brain, between the brain and the periphery and vice-versa, playing a fundamental role in physiology and pathology. The evidence that EVs might be able to cross the blood-brain barrier (BBB) make them very promising candidates as nanocarriers to treat brain pathologies. EVs contain a cocktail of bioactive factors, yet the...
