Update publication information. Neonatal infection and sepsis are common for preterm infants due to their immature immune system. Acute changes of proteins in the cerebrospinal fluid (CSF), potentially affect the immature brain of preterm neonates. In this study, collected human CSF samples were processed according to the enhanced filter-aided sample preparation (eFASP) protocol and run on a Dionex RSLC UPLC System coupled to an Orbitrap Fusion Lumos Mass Spectrometer. Protein annotation and quantification were carried out using MaxQuant (version 1.5.2.8) against the Uniprot database (homo sapiens, UP0000085640).
