The neuronal response to trauma of the brain and spinal cord was examined by staining sections of injured central nervous system (CNS) with a monoclonal antibody (TuJ1) that recognizes class III beta-tubulin exclusively. Because class III beta-tubulin is expressed by neurons and not by glia, this monoclonal antibody stains neuronal cell bodies, dendrites,(More)
PURPOSE The goal of this study was to define the temporal changes in gene expression after retinal injury and to relate these changes to the inflammatory and reactive response. A specific emphasis was placed on the tetraspanin family of proteins and their relationship with markers of reactive gliosis. METHODS Retinal tears were induced in adult rats by(More)
We developed and characterized a mouse model of primary ocular blast injury. The device consists of: a pressurized air tank attached to a regulated paintball gun with a machined barrel; a chamber that protects the mouse from direct injury and recoil, while exposing the eye; and a secure platform that enables fine, controlled movement of the chamber in(More)
Newly generated neurons are continuously added to the olfactory epithelium and olfactory bulbs of adult mammals. Studies also report newly generated neurons in the piriform cortex, the primary cortical projection site of the olfactory bulbs. The current study used BrdU-injection paradigms, and in vivo and in vitro DiI tracing methods to address three(More)
During the development of the central nervous system (CNS), adhesive molecules promote the formation of axonal pathways and appropriate neuronal connections by facilitating cellular interactions. In addition to the interactions that bring neurons together, recent evidence suggests inhibition of neuronal interactions also plays a role by restricting axons to(More)
A slow progressive death of neurons is the hallmark of neurodegenerative diseases, such as glaucoma. A therapeutic candidate, erythropoietin (EPO), has shown promise in many models of these diseases; however, it also causes polycythemia, a potentially lethal side effect. We have developed a novel mutant form of EPO that is neuroprotective but no longer(More)
After an injury to the central nervous system, a dramatic change in the astrocytes bordering the wound occurs. The most characteristic feature of this process, termed reactive gliosis, is the upregulation of the intermediate filament protein, glial fibrillary acidic protein. In the present study, we show that reactive astrocytes express high levels of(More)
Only a few proteins are known to be exclusively expressed in central nervous system (CNS) myelin. A novel surface membrane protein expressed only in CNS myelin and oligodendrocytes of higher vertebrates has been identified by a monoclonal antibody. This CNS myelin/oligodendrocyte-specific protein, MOSP, has a molecular weight of 48 kDa and a pI of(More)
The monoclonal antibody, A2B5, that recognizes vertebrate gangliosides also recognizes embryonic cells in the medicinal leech (Hirudo medicinalis) in a spatially and temporally regulated way. Furthermore, A2B5-positive glycolipids could be isolated from embryonic leeches. Early in development A2B5 labeled axon tracts within the central nervous system(More)
