  abstract  = {In preterm infants, phenobarbital is the first-line antiepileptic drug for neonatal seizures while caffeine is used for the treatment of apnea. Data from experimental animals suggest that phenobarbital and other anticonvulsants are toxic for the developing brain, while neuroprotective effects have been reported for caffeine both in newborn rodents and preterm human infants. To characterize the interaction of phenobarbital and caffeine in the hippocampus of the developing rodent brain, we examined the effects of both drugs given separately or together on postnatal neurogenesis after administration to neonatal rats throughout postnatal day (P) 4 to P6. Phenobarbital treatment (50 mg/kg) resulted in a significant decrease of proliferative capacity in the dentate gyrus. Phenobarbital also reduced expression of neuronal markers (doublecortin (DCX), calretinin, NeuN), neuronal transcription factors (Pax6, Sox2, Tbr1/2, Prox1), and neurotrophins (NGF, BDNF, NT-3) up to 24 h after the last administration. The phenobarbital-mediated impairment of neurogenesis was largely ameliorated by preconditioning with caffeine (10 mg/kg). In contrast, caffeine alone reduced proliferative capacity and expression of the neuronal markers DCX and NeuN at 6 h, but increased expression of neurotrophins and neuronal transcription factors at 6 and 12 h. These results indicate that administration of phenobarbital during the vulnerable phase of brain development negatively interferes with neuronal development, which can be prevented in part by co-administration of caffeine.},

  abstract  = {Sequelae of prematurity triggered by oxidative stress and free radical-mediated tissue damage have coined the term "oxygen radical disease of prematurity". Caffeine, a potent free radical scavenger and adenosine receptor antagonist, reduces rates of brain damage in preterm infants. In the present study, we investigated the effects of caffeine on oxidative stress markers, anti-oxidative response, inflammation, redox-sensitive transcription factors, apoptosis, and extracellular matrix following the induction of hyperoxia in neonatal rats. The brain of a rat pups at postnatal Day 6 (P6) corresponds to that of a human fetal brain at 28-32 weeks gestation and the neonatal rat is an ideal model in which to investigate effects of oxidative stress and neuroprotection of caffeine on the developing brain. Six-day-old Wistar rats were pre-treated with caffeine and exposed to 80\% oxygen for 24 and 48 h. Caffeine reduced oxidative stress marker (heme oxygenase-1, lipid peroxidation, hydrogen peroxide, and glutamate-cysteine ligase catalytic subunit (GCLC)), promoted anti-oxidative response (superoxide dismutase, peroxiredoxin 1, and sulfiredoxin 1), down-regulated pro-inflammatory cytokines, modulated redox-sensitive transcription factor expression (Nrf2/Keap1, and NFκB), reduced pro-apoptotic effectors (poly (ADP-ribose) polymerase-1 (PARP-1), apoptosis inducing factor (AIF), and caspase-3), and diminished extracellular matrix degeneration (matrix metalloproteinases (MMP) 2, and inhibitor of metalloproteinase (TIMP) 1/2). Our study affirms that caffeine is a pleiotropic neuroprotective drug in the developing brain due to its anti-oxidant, anti-inflammatory, and anti-apoptotic properties.},
