Neuroprotective role of erythropoietin in spinal cord ischemic injury: Where have we been and where are we going?
2018
I read with great interest the study recently published by Yamanaka and colleagues,1 reporting the results of the study aimed to pharmacologically induce b common receptor (bcR) subunit upregulation before ischemia to optimize the neuroprotective effect of erythropoietin (EPO). The authors hypothesized that bcR subunit upregulation by diazoxide (DZ) before ischemia amplifies the neuroprotective effects of EPO in mice after spinal cord injury (SCI). They reported that that optimal bcR upregulation occurred at 36 hours after DZ administration, and the optimal DZ dosage for bcR induction was 20 mg/kg. Motor function at 48 hours after treatment was significantly better preserved in the DZ with …
Severe Perinatal Hypoxic-Ischemic Brain Injury Induces Long-Term Sensorimotor Deficits, Anxiety-Like Behaviors and Cognitive Impairment in a Sex-, Ag…
2019
Perinatal brain injury (PBI) leads to neurological disabilities throughout life, from motor deficits, cognitive limitations to severe cerebral palsy. Yet, perinatal brain damage has limited therapeutic outcomes. Besides, the immature brain of premature children is at increased risk of hypoxic/ischemic (HI) injury, with males being more susceptible to it and less responsive to protective/therapeutical interventions. Here, we model in male and female C57BL/6 mice, the impact of neonatal HI and the protective effects of neonatal handling (NH), an early life tactile and proprioceptive sensory stimulation. From postnatal day 1 (PND1, modeling pre-term) to PND21 randomized litters received either…
