To get further insight into inflammatory responses involved, we experimentally investigated the immune response of microglia in an inflammation-sensitized neonatal hypoxia-ischemia (HI) model.Transcriptomic analysis of microglia isolated from brains following inflammation-sensitized HI brain injury revealed a strong upregulation of leukocyte recruitment and pro-inflammatory markers. Specifically, markers associated with neutrophil-mediated immune responses and chemotaxis were upregulated in the inflammation-sensitized HI group compared to the non-inflammation-sensitized HI and control groups. Serpine 1 and Selp could be identified as specifically upregulated markers indicating an acute inflammatory condition before HI injury.Our study revealed preliminary data about a microglia population which is primed to recruit peripheral neutrophils to infiltrate the brain and mediate neutrophil immune response. We showed a contribution to neutrophil activation in case of inflammation following HI in the brain. Targeting microglia-mediated neutrophil recruitment can indicate a possible treatment approach in case of inflammation-sensitized HI brain injury. 000280026 536__ $$0G:(DE-HGF)POF4-352$$a352 - Disease Mechanisms (POF4-352)$$cPOF4-352$$fPOF IV$$x0 000280026 536__ $$0G:(DE-HGF)POF4-354$$a354 -
