WebFollowing an intraventricular hemorrhage (IVH), red blood cell lysis and hemoglobin (Hb) oxidation with the release of heme can cause sterile neuroinflammation. In this study, we measured Hb derivates and cellular adhesion molecules ICAM-1 and VCAM-1 with cell-free miRNAs in cerebrospinal fluid (CSF) samples obtained from Grade-III and Grade-IV … WebFeb 11, 2024 · In this study, we hypothesize that production of reactive oxygen species (ROS) by Hb-metabolites, is central to the detrimental pathways following preterm IVH. Results show that in vitro exposure of an immature primary rat mixed glial cell culture to oxidized Hb, rather than oxyHb, led to a similar damaging response as exposure to …
