abstract = {Inflammasomes are known to contribute to brain damage after
acute ischemic stroke (AIS). TAK1 is predominantly expressed
in microglial cells and can regulate the NLRP3 inflammasome,
but its impact on other inflammasomes including NLRC4 and
AIM2 after AIS remains elusive. EPO has been shown to reduce
NLRP3 protein levels in different disease models. Whether
EPO-mediated neuroprotection after AIS is conveyed via an
EPO/TAK1/inflammasome axis in microglia remains to be
clarified. Subjecting mice deficient for TAK1 in
microglia/macrophages (Mi/MΦ) to AIS revealed a significant
reduction in infarct sizes and neurological impairments
compared to the corresponding controls. Post-ischemic
increased activation of TAK1, NLRP3, NLRC4, and AIM2
inflammasomes including their associated downstream cascades
were markedly reduced upon deletion of Mi/MΦ TAK1. EPO
administration improved clinical outcomes and dampened
stroke-induced activation of TAK1 and inflammasome cascades,
which was not evident after the deletion of Mi/MΦ TAK1.
Pharmacological inhibition of NLRP3 in microglial BV-2 cells
did not influence post-OGD IL-1β levels, but increased
NLRC4 and AIM2 protein levels, suggesting compensatory
activities among inflammasomes. Overall, we provide evidence
that Mi/MΦ TAK1 regulates the expression and activation of
the NLRP3, NLRC4, AIM2 inflammasomes. Furthermore, EPO
mitigated stroke-induced activation of TAK1 and
inflammasomes, indicating that EPO conveyed neuroprotection
might be mediated via an EPO/TAK1/inflammasome axis.},
