abstract = {Astrocytes support normal brain function, but may also
contribute to neurodegeneration when they become reactive
under pathological conditions such as stroke. However, the
molecular underpinnings of this context-dependent interplay
between beneficial and detrimental properties in reactive
astrogliosis have remained incompletely understood.
Therefore, using the RiboTag technique, we immunopurified
translating mRNAs specifically from astrocytes 72 hr after
transient middle cerebral artery occlusion in mice (tMCAO),
thereby generating a stroke-specific astroglial translatome
database. We found that compared to control brains, reactive
astrocytes after tMCAO show an enrichment of transcripts
linked to the A2 phenotype, which has been associated with
neuroprotection. However, we found that astrocytes also
upregulate a large number of potentially neurotoxic genes.
In total, we identified the differential expression of 1,003
genes and 38 transcription factors, of which Stat3, Sp1, and
Spi1 were the most prominent. To further explore the effects
of Stat3-mediated pathways on stroke pathogenesis, we
subjected mice with an astrocyte-specific conditional
deletion of Stat3 to tMCAO, and found that these mice have
reduced stroke volume and improved motor outcome 72 hr
after focal ischemia. Taken together, our study extends the
emerging database of novel astrocyte-specific targets for
stroke therapy, and supports the role of astrocytes as
critical safeguards of brain function in health and
disease.},
