Physical exercise effects on brain health and cognitive performance have been described. Synaptic remodeling in hippocampus induced by physical exercise has been described in animal models, but the underlying mechanisms remain poorly understood. Changes in astrocytes, the glial cells involved in synaptic remodeling, need more characterization. We investigated the effect of moderate treadmill ex...
Twenty areas of retinal vascular occlusion from ten eyes of 6 diabetic patients were studied by immunohistochemistry to type IV collagen (basement membranes), von Willebrand factor (endothelial cells), and to glial fibrillary acid protein (glial cells) on serial sections. In all studied lesions immunoreactivity to type IV collagen and von Willebrand factor was confined to the retinal vascular w...
In the course of adult hippocampal neurogenesis, new cells go through a series of stages associated with proliferative activity. The most highly proliferative cell type is an intermediate precursor cell, called type-2 cell. We here report that on the level of type-2 cells a transition takes place between features associated with the glial and the neuronal lineage. We show that stem-cell marker ...
The purpose of this study was to generate quadruple fluorescent protein (QFP) transgenic mice as a source for QFP-expressing neural stem and progenitor cells (NSCs/NPCs) that could be utilized as a tool for transplantation research. When undifferentiated, these NSCs only express cyan fluorescent protein (CFP); however, upon neuronal differentiation, the cells express yellow fluorescent protein ...
BACKGROUND AND PURPOSE Prenatal glucocorticoids prevent germinal matrix hemorrhage in premature infants. The underlying mechanism, however, is elusive. Germinal matrix is enriched with angiogenic vessels exhibiting paucity of pericytes and glial fibrillary acidic protein-positive astrocyte end feet. Therefore, we asked whether glucocorticoid treatment would suppress angiogenesis and enhance per...
Focal epilepsy often develops following traumatic, ischemic, or infectious brain injury. While the electrical activity of the epileptic brain is well characterized, the mechanisms underlying epileptogenesis are poorly understood. We have recently shown that in the rat neocortex, long-lasting breakdown of the blood-brain barrier (BBB) or direct exposure of the neocortex to serum-derived albumin ...
Blast traumatic brain injury (bTBI) affects civilians, soldiers, and veterans worldwide and presents significant health concerns. The mechanisms of neurodegeneration following bTBI remain elusive and current therapies are largely ineffective. It is important to better characterize blast-evoked cellular changes and underlying mechanisms in order to develop more effective therapies. In the presen...
