Infection during the neonatal period commonly induces apnea episodes, and the proinflammatory cytokine IL-1beta may serve as a critical mediator between these events. To determine the mechanism by which IL-1beta depresses respiration, we examined a prostaglandin E(2) (PGE(2))-dependent pathway in newborn mice and human neonates. IL-1beta and transient(More)
BACKGROUND Apnea associated with infection and inflammation is a major medical concern in preterm infants. Prostaglandin E(2) (PGE(2)) serves as a critical mediator between infection and apnea. We hypothesize that alteration of the microsomal PGE synthase-1 (mPGES-1) PGE(2) pathway influences respiratory control and response to hypoxia. METHODS Nine-d-old(More)
Prostaglandin E2 (PGE2) serves as a critical mediator of hypoxia, infection, and apnea in term and preterm babies. We hypothesized that the prostaglandin E receptor type 3 (EP3R) is the receptor responsible for PGE2-induced apneas. Plethysmographic recordings revealed that IL-1β (ip) attenuated the hypercapnic response in C57BL/6J wild-type (WT) but not in(More)
OBJECTIVE To determine whether infection, with associated eicosanoid release, is a main cause of respiratory disruption in neonates, by measuring levels of prostaglandin E2 (PGE2) and its metabolite (PGEM) in cerebrospinal fluid (CSF). STUDY DESIGN Of 59 eligible infants, 25 preterm infants (mean gestational age, 28 ± 0.5 weeks) and 22 full-term infants(More)
