IFNG and necrotizing enterocolitis: Elevated intestinal IFN-γ levels have been reported in NEC patients [71], however no significant differences in IFN-γ were found between formula-fed-hypoxic NEC rats and non-hypoxic formula-fed groups with mild intestinal damage in a study similar to ours [72] and in separate studies ileal IFN-γ mRNA was not related to NEC development in neonatal rat pups [68].
