Transplantation of bone marrow stromal cells (BMSCs) reduces astrogliosis, decreases scar thickness and improves neurological functional recovery after brain damage. It is believed that transplanted BMSCs have a profound influence on astrocytes. To obtain the possible mechanism in their interaction, a co-culture system between BMSCs and astrocytes were set to investigate whether BMSCs could mod...
Alzheimer's disease (AD) is pathologically characterized by beta-amyloid (Aβ) plaques and Tau pathology. It is well-established that Aβ plaques are surrounded by reactive astrocytes, highly expressing glial fibrillary acidic protein (GFAP). In order to study the cellular interaction of reactive astrocytes with Aβ plaques, we crossbred mice overexpressing amyloid precursor protein (APP) with the...
In this report, we investigated whether reactive astrocytes produce neuregulins (glial growth factor 2/heregulin/acetylcholine receptor-inducing activity or neu differentiation factor) and its putative receptors, ErbB2 and ErbB3 tyrosine kinases, in the injured CNS in vivo. Significant immunoreactivities with anti-neuregulin, anti-ErbB2, and anti-ErbB3 antibodies were detected on astrocytes at ...
The reactive changes in different types of astrocytes were analyzed in parkinsonian syndromes in order to identify common reactions and their relationship to disease severity. Immunohistochemistry was used on formalin-fixed, paraffin-embedded sections from the putamen, pons, and substantia nigra from 13 Parkinson disease (PD), 29 multiple-system atrophy (MSA), 34 progressive supranuclear palsy ...
Although the importance of reactive astrocytes during CNS pathology is well established, the function of astroglia in adult CNS homeostasis is less well understood. With the use of conditional, astrocyte-restricted protein synthesis termination, we found that selective paralysis of GFAP(+) astrocytes in vivo led to rapid neuronal cell loss and severe motor deficits. This occurred while structur...
Recent clinical data have led to the consideration of sexual steroids as new potential therapeutic tools for multiple sclerosis. Selective estrogen receptor modulators can exhibit neuroprotective effects like estrogen, with fewer systemic estrogen side effects than estrogen, offering a more promising therapeutic modality for multiple sclerosis. The important role of astrocytes in a proinflammat...
Reactive astrogliosis is the process by which astrocytes respond to central nervous system injury or disease. The origin of these cells is under debate. Herein, we contribute to comments regarding our recent report and discuss the context of our findings. One of the main goals in the field of neuroscience is to understand the cellular basis and molecular pathways that underlie injury and diseas...
