Targeting the Neurovascular Unit in Brain Trauma.

Targeting the Neurovascular Unit in Brain Trauma. CNS Neurosci Ther. 2014 Dec 5; Authors: Lok J, Wang XS, Xing CH, Maki TK, Wu LM, Guo SZ, Noviski N, Arai K, Whalen MJ, Lo EH, Wang XY Abstract Although the neurovascular unit was originally developed as a conceptual framework for stroke, it is now recognized that these cell-cell interactions play critical roles in many other CNS disorders as well. In brain trauma, perturbations within the neurovascular unit may be especially important. Changes in neurovascular coupling may disrupt blood flow and metabolic regulation. Disruption of transmitter release-reuptake kinetics in neurons and astrocytes may augment excitotoxicity. Alterations in gliovascular signaling may underlie blood-brain barrier disruptions and traumatic edema. Perturbations in cell-cell signaling between all neuronal, glial, and vascular compartments may increase susceptibility to cell death. Finally, repairing the brain after trauma requires the integrated restoration of all neural, glial, and vascular connectivity for effective functional recovery. Just as in stroke, saving neurons alone may also be insufficient for treating brain trauma. In this minireview, we attempt to briefly highlight some of these pathways to underscore the importance of rescuing the entire neurovascular unit in brain trauma.

Scientists at the University of Texas said they saw an improvement of one point on a six-point scale after six months of testing the therapy on stroke patients within 72 hours of symptoms beginning.

Researchers in Barcelona analysed records of more than 2,700 stroke victims in Spain and also found that having a 984-foot (300m) 'buffer' of green space around the home reduced stroke risk.

In this study, we report the effects of short-term preconditioning of hMSCs via three-dimensional (3D) aggregation on stroke lesion recovery after intra-arterial (IA) transplantation of 3D aggregate-derived hMSCs (Agg-D hMSCs) in a transient middle cerebral artery occlusion (MCAO) stroke model. Compared with two-dimensional (2D) monolayer culture, Agg-D hMSCs exhibited increased resistance to ischemic stress, secretory function and therapeutic outcome. Short-term preconditioning via 3D aggregation reconfigured hMSC energy metabolism and altered redox cycle, which activated the PI3K/AKT pathway and enhanced resistance to in...

This study sought to evaluate associations between nephrolithiasis and hemorrhagic and ischemic stroke using a national sample cohort from Korea. Data from 2002 to 2013 were collected for individuals ≥ 20 years of age in the Korean National Health Insurance Service (NHIS)-National Sample Cohort. We extracted nephrolithiasis patients (n = 22,636) and 1:4 matched controls (n = 90,544) and analyzed the occurrence of stroke. Matching was performed based on age, sex, income, region of residence, hypertension, diabetes mellitus, and dyslipidemia history. Crude and adjusted hazard ratios (HRs) were calculated using Cox proport...

Publication date: 15 November 2019Source: NeuroImage, Volume 202Author(s): Jeremy J. Purcell, Robert W. Wiley, Brenda RappAbstractIdentifying the neural changes that support recovery of cognitive functions after a brain lesion is important to advance our understanding of human neuroplasticity, which, in turn, forms the basis for the development of effective treatments. To date, the preponderance of neuroimaging studies has focused on localizing changes in average brain activity associated with functional recovery. Here, we took a novel approach by evaluating whether cognitive recovery in chronic stroke is related to increa...

The study here shows that given a population of individuals with hypertension, those who manage to control their high blood pressure go on to suffer lesser degrees of cognitive decline. Numerous mechanisms may link hypertension to structural damage in the brain: degeneration of the blood-brain barrier, allowing inappropriate molecules and cells into the brain, leading to neuroinflammation and other effects; rupture of capillaries causing microbleeds, effectively tiny strokes; outright pressure damage in tissue very close to small vessels that directly harms brain cells; and so forth. This damage adds up, but note that it i...
