Challenges of neural interfaces for stroke motor rehabilitation
More than 85% of stroke survivors suffer from different degrees of disability for the rest of their lives. They will require support that can vary from occasional to full time assistance. These conditions are also associated to an enormous economic impact for their families and health care systems. Current rehabilitation treatments have limited efficacy and their long-term effect is controversial. Here we review different challenges related to the design and development of neural interfaces for rehabilitative purposes. We analyze current bibliographic evidence of the effect of neuro-feedback in functional motor rehabilitat...

The cell-specific roles of Nrf2 in acute and chronic phases of ischemic stroke
CNS Neurosci Ther. 2023 Sep 16. doi: 10.1111/cns.14462. Online ahead of print.ABSTRACTIschemic stroke refers to the sudden loss of blood flow in a specific area of the brain. It is the fifth leading cause of mortality and the leading cause of permanent disability. The transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) controls the production of several antioxidants and protective proteins and it has been investigated as a possible pharmaceutical target for reducing harmful oxidative events in brain ischemia. Each cell type exhibits different roles and behaviors in different phases post-stroke, which is...

Brain Pathology in COVID-19: Clinical Manifestations and Potential Mechanisms
AbstractNeurological manifestations of coronavirus disease 2019 (COVID-19) are less noticeable than the respiratory symptoms, but they may be associated with disability and mortality in COVID-19. Even though Omicron caused less severe disease than Delta, the incidence of neurological manifestations is similar. More than 30% of patients experienced “brain fog”, delirium, stroke, and cognitive impairment, and over half of these patients presented abnormal neuroimaging outcomes. In this review, we summarize current advances in the clinical findings of neurological manifestations in COVID-19 patients and compare them with ...

Functional effects of haemoglobin can be rescued by haptoglobin in an in vitro model of subarachnoid haemorrhage
Subarachnoid haemorrhage causes significant cognitive and functional disability in survivors, and one contributing factor is exposure of neurons to haemoglobin causing cell loss and dysfunction. In this in vitro subarachnoid haemorrhage model, haemolysate application to cultured neurons impairs cytoskeletal integrity. Furthermore, amplitude of AMPA receptor-mediated synaptic currents is reduced by haemolysate, driven by reduction in GluA1 expression. These deficits can be prevented with application of exogenous haptoglobin without off-target effects. These results provide new insight into neuronal dysfunction in haemorrhag...

A modified murine photothrombotic stroke model: a minimally invasive and reproducible cortical and sub-cortical infarct volume and long-term deficits
In conclusion, this modified model helps to understand stroke pathogenesis and minimize the animals' numbers which help to increase the scientific and statistical potential in pre-clinical studies.PMID:37656197 | DOI:10.1007/s00221-023-06696-5

Monocyte-related cytokines/chemokines in cerebral ischemic stroke
CONCLUSION: This review focuses on the function and mechanism of the cytokines secreted by monocytes in the process of ischemic stroke and provides novel targets for treating cerebral ischemic stroke.PMID:37452512 | DOI:10.1111/cns.14368

Modulation of the autophagy ‐lysosomal pathway and endoplasmic reticulum stress by ketone bodies in experimental models of stroke
We report for the first time that the protective effect of β-hydroxybutyrate (BHB) against stroke and glucose deprivation is enantiomer selective. We discovered that D-BHB treatment prevented the cleavage of the lysosomal membrane protein LAMP2, maintained lysosome integrity and stimulated the autophagic flux. Also, D-BHB notably reduced the activation of the PERK and IRE1α branches of the unfolded protein response (UPR), attenuating protein synthesis inhibition and preventing endoplasmic reticulum stress. Together our results support the therapeutic use of D-BHB treatment post-ischemia, by preventing the loss of proteos...

The interaction between intestinal microenvironment and stroke
CONCLUSION: The structure and function of the intestinal environment can influence neurological function and cerebral ischemic outcome. Improving the intestinal microenvironment by targeting the gut microbiota may be a new direction in treating stroke.PMID:37309254 | DOI:10.1111/cns.14275
