Topic: Astrocyte

Ads by Google      Astrocytes This all may mean that glutamate release from neurons triggers astrocytes to produce trophic factors, which then help neurons process information for memory. Together the research is not only making researchers rethink how the brain operates, but also how to treat it when it malfunctions. The communication flows both ways, with neurons also being able to talk to the astrocytes through their own glutamate release. http://web.sfn.org/content/Publications/BrainBriefings/astrocytes.html   (802 words)      Transforming Growth Factor-{beta} Mediates Astrocyte-Specific Regulation of Brain Endothelial Anticoagulant Factors • ... of the astrocytic response in acute stroke therapy. astrocytic response to cerebral ischemia is very complex and of this process, we examined the hypothesis that astrocyte regulation http://stroke.ahajournals.org/cgi/content/full/30/8/1671   (4482 words)      CD95 (Fas/Apo-1) as a Receptor Governing Astrocyte Apoptotic or Inflammatory Responses: A Key Role in Brain ... responsible for apoptosis in human astrocytes are poorly defined.
