NOS2 and necrotizing enterocolitis: Compared with the NEC+Succi group, the NEC+Succi+SUCNR1‐Ab group presented a synchronized downregulation of the M1‐type marker iNOS (Figure 6e) and the proinflammatory factor TNF‐α (Figure 6g), accompanied by a rebound in the expression of the M2‐type marker Arg1 (Figure 6f) and the anti‐inflammatory factor IL‐10 (Figure 6h), compared with the NEC+Succi group (p < 0.05).
