One of the striking observations was the highly modulated expression of inflammatory genes related to the IL-17 pathway including such as pro-inflammatory cytokines (CXCL8), chemokines (CXCL5 and CXCL10) and antimicrobials (DEF5A, DEF6A, LCN2, NOS2) in the intestine of neonates diagnosed with NEC. The gene discussed is NOS2; the disease is necrotizing enterocolitis.
