Back Again to the Future: A New Era for Cerebroprotection

Annals of Neurology, EarlyView.
Cerebroprotection is a fresh framework for designing neurological therapy that targets glia and vascular cells, in addition to neurons. In the future, successful cerebroprotection will involve targeting all elements of the neurovascular unit. Preclinical trials must include functional outcomes, as well as lesion morphometry.

Endothelial Netrin‐4 regulates oligodendrocyte precursor cell proliferation and differentiation via ET‐1 signaling in preterm white matter injury

Brain Pathology, EarlyView.
Our findings show early increased Netrin‐4 in mice with PWMI boosts angiogenesis and OPCs proliferation. Later, high levels hinder OPCs differentiation into mature cells, impairing myelination. It may act by stimulating ET‐1 secretion. Abstract Perinatal hypoxia–ischemia is a leading cause of preterm white matter injury (PWMI), yet mechanisms ...

Closed cranial window rodent model for investigating hemodynamic response to elevated intracranial pressure

Animal Models and Experimental Medicine, 2021
Background Elevated intracranial pressure (ICP) occurs in several physiological and pathological conditions, yet long‐term sequellae are not common, which implies that blood flow is preserved above ischemic thresholds.
