TLR4 and necrotizing enterocolitis: The same pattern of decreased brain and ileum TLR-4 protein levels compared to NEC was demonstrated when NAC was administered only to the offspring (NEC-NAC) (brain 1.03 ± 0.32 vs. 2.5 ± 0.6 U; ileum 0.09 ± 0.01 vs. 0.24 ± 0.04 U, p < 0.05) and to both dams and offspring (NAC-NEC-NAC) (brain 0.68 + 0.11 vs. 2.5 ± 0.6 U; p < 0.05; ileum 0.07 + 0.02 vs. 0.24 ± 0.04 U; p < 0.05) (Figs. 2 and 3).
