Astrocytes: Cell Biology and Pathology of Astrocytes -
With the advent of cell type–specific gene databases, the ability to target individual cell types in the CNS has exploded. Previously, in vivo studies of astrocyte biology were hampered by a lack of genetic lines to drive or knock out gene expression specifically in astrocytes while leaving neural progenitor cells NPCs, neurons, and other glial cells unaffected.
Sep 20, 2006 PI3K inhibition by 30 μM LY294002 decreased the migration extent of wild-type astrocytes by 15.4 ± 3.6% and did the same for PEA-15−/− astrocytes −21.7% ± 2.5%, demonstrating that Akt activity is also required for full astrocyte motility but that it does not interfere with the specific effect of PEA-15 on cell migration.
Mar 20, 2020 Astrocytes improve survival of neurons damaged by cisplatin. a-d. Survival of neurons a, b and astrocytes c, d after exposure to cisplatin. Primary cultures of cortical neurons 12 days in vitro or cortical astrocytes were treated with increasing doses of cisplatin or vehicle for 24 h, then the cisplatin was removed and replaced with media.
Temporal profile of astrocytes and changes of oligodendrocyte-based myelin following middle cerebral artery occlusion in diabetic and non-diabetic rats. Int J Biol Sci. 2013;92190-9 10.

Astrocytes and microglia 3 x 10 4 cells/well were infected with T. cruzi at MOI = 51 parasitescell for 2–96 h Figure 2. Infection rate was evaluated by immunofluorescence by counting the number of cells and the number of parasites stained with a DNA intercalator DAPI.
Overexpression of c-MYC promotes an undifferentiated phenotype in cultured astrocytes and allows elevated Ras and Akt signaling to induce gliomas from GFAP-expressing cells in mice - Volume 1 Issue 2 - ANDREW B. LASSMAN, CHENGKAI DAI, GREGORY N. FULLER, ANDREW J. VICKERS, ERIC C. HOLLANDDec 04, 2015 Astrocytes may play important roles in the pathogenesis of Alzheimer’s disease AD by clearing extracellular amyloid beta Aβ through endocytosis and degradation. We recently showed that metallothionein 3 Mt3, a zinc-binding metallothionein that is enriched in the central nervous system, contributes to actin polymerization in astrocytes. Because actin is likely involved in the.
Abstract. Motor neurons MNs and astrocytes ACs are implicated in the pathogenesis of amyotrophic lateral sclerosis ALS, but their interaction and the sequence of molecular events leading to MN death remain unresolved.
Exposure of naive MM astrocytes to vCJD-infected MM cell inoculum resulted in a substantially increased level of PrP Sc compared with astrocytes during the first passage at 8 dpe. A fourfold increase of PrP Sc was also observed when VV naive astrocytes were exposed to a cell lysate from sCJD VV2-infected VV astrocytes Fig. 4, C and D.

Substantial progress has been made recently in determining functions and mechanisms of reactive astrogliosis and in identifying roles of astrocytes in CNS disorders and.
Reactive astrocytes, for example, can influence the responses of other cell types after TBI, both within the brain and in the periphery. Ablation of reactive astrocytes has resulted in an increase in leukocyte infiltration in a stab wound injury model, leading to neurodegeneration Bush et al. 1999.Search results for astrocytes at Sigma-Aldrich. Summary This gene encodes a death effector domain-containing protein, which is a major phosphoprotein in astrocytes, and an endogenous substrate for protein kinase C. Studies using knockout mice suggest that this protein may protect astrocytes from TNF-induced apoptosis.Please use one of the following formats to cite this article in your essay, paper or report APA.

Kraft-Terry, Joshua D. Schlautman, Pawel Ciborowski, David J. Volsky, Howard E. GendelmanFlow cytometry analysis confirmed that there was about 5% LAMP-1-positive staining on the cell surface of the WT astrocytes and about 15% LAMP-1-positive staining on the surface of iTat astrocytes Fig. 5, B and C. These results showed that Tat expression also led to increased constitutive lysosomal exocytosis.APCs were consistently detected in a small region ahead of the perinatal astrocytes during development of the human retina Fig. 1A⤻-F⤻. The spread of APCs and perinatal astrocytes was centered on the ONH; these cells followed a curved pattern of migration in the temporal retina, mimicking the pattern of nerve fiber bundles and blood vessels.Astrocytes provide the environment necessary for neurons to correctly wire together and transmit signals. During diseases like Alzheimer’s disease, astrocytes can become reactive—switching from a supportive state to a diseased state, in which neuron-killing toxins are secreted.
