Multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), an animal model of MS, are inflammatory demyelinating diseases of the central nervous system. The inflammatory attacks lead to glial dysfunction and death, axonal damage, and neurological deficits. Numerous studies in rat suggest that extracellular calcium influx, via voltage-gated(More)
Ionotropic AMPA/kainate (KA) glutamate receptors are important for vasculature-astrocyte interaction in the central nervous system (CNS). To date, little is known about the expression of AMPA/KA receptors in the perivascular environment. Using double labeling immunohistochemistry on mouse and rat spinal cord sections, we show first evidence that(More)
Our recent study on ionotropic (+/-)-alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA)/kainate (KA) type glutamate receptors in mouse spinal cord revealed differences compared with reports on other species. Inconsistencies in such findings may reflect real inter-species variability or differences in technique. To date, no comprehensive study(More)
Both multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), its animal model, involve inflammatory attack on central nervous system (CNS) white matter, leading to demyelination and axonal damage. Changes in astrocytic morphology and function are also prominent features of MS and EAE. Resting astrocytes form a network that is(More)
Spinal cord white matter is susceptible to AMPA/kainate (KA)-type glutamate receptor-mediated excitotoxicity. To understand this vulnerability, it is important to characterize the distribution of AMPA/KA receptor subunits in this tissue. Using immunohistochemistry and laser confocal microscopy, we studied the expression sites of AMPA/KA receptor subunits in(More)
