Objective: to review immunological mechanisms involved in extreme prematurity, their effects on the most relevant systems and new therapeutical approaches.</p>info:eu-repo/semantics/openAccessFollow-upPerinatal InflammationPrematurityPreterm InfantSustained InflammationSyndromeSÍNDROME INFLAMATORIO PERINATAL PERSISTENTE DEL PREMATURO EXTREMO.
