Temporal and Spatial Gene Expression Dynamics in Neonatal HI Hippocampus with Focus on Arginase

Key Points

Neonatal microglia drive scar formation through the activation of key signaling pathways, including PI3K-Akt and TGF-β.
Significant transitions occur in microglial responses, from efferocytosis to fibrotic remodeling after hypoxia-ischemia.
Analysis of gene expression provides insight into potential interventions targeting ARG1-linked signaling pathways.
Findings indicate that microglia are critical regulators in neonatal hippocampal injury response, implying new therapeutic possibilities.

Abstract

Neonatal microglia transition from early efferocytic responses to later fibrotic remodeling after HI, driven by the persistent activation of PI3K-Akt, TGF-β, and Wnt/FZD4 pathways. These findings identify microglia as central regulators of neonatal scar formation and highlight therapeutic targets within ARG1-linked signaling.
