Mixed lineage kinase domain-like (MLKL) protein was recently found to play a critical role in necrotic cell death. To explore its role in neurological diseases, we measured MLKL protein expression after ischemia injury in a mouse model. We found that MLKL expression significantly increased 12 h after ischemia/reperfusion (I/R) injury with peak levels at 48 h. Inhibition of MLKL by intraperitoneal administration of NSA significantly reduced infarct volume and improved neurological deficits after 75 min of ischemia and 24 h of reperfusion. Further, we found NSA reduced MLKL levels via the ubiquitination proteasome pathway, but not by inhibiting RNA transcription. Interestingly, NSA administration increased cleaved PARP-1 levels, indicating the protective effects of MLKL inhibition is not related to apoptosis. These findings suggest MLKL is a new therapeutic target for neurological pathologies like stroke. Therefore, promoting degradation of MLKL may be a novel avenue to reduce necrotic cell death after ischemic brain injury.
