First, we assessed the systemic pro-inflammatory response to neonatal sepsis, via quantification of circulating levels of key cytokines (TNF, IFNg, IL- 6, S100 A9, IL- 10, bFGF), chemokines (KC, RANTES, MCP- 1) and growth factors (G-CSF, GM-CSF) (Figure S2). This evidence concerns the gene FGF2 and Neonatal sepsis.
