Protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK) is a major signal transducer of the endoplasmic reticulum stress response (ERSR) pathway. Outcomes of PERK activation range from abrogating ER stress to induction of cell death, dependent on its level, duration, and cellular context. Current data demonstrate that after mouse spinal cord injury (SCI), acute inhibition of PERK (0–72 h) with the small molecule inhibitor GSK2656157 reduced ERSR while improving white matter sparing and hindlimb locomotion recovery. GSK2656157-treated mice showed increased numbers of oligodendrocytes at the injury epicenter. Moreover, GSK2656157 protected cultured primary mouse oligodendrocyte precursor cells from ER stress-induced cytotoxicity. These findings suggest that in the context of SCI, excessive acute activation of PERK contributes to functionally relevant white matter damage. Pharmacological inhibition of PERK is a potential strategy to protect central nervous system (CNS) white matter following acute injuries, including SCI.
