NF-κB protein level after administration of M, Q, and/or C in mice induced by S. Typhi shows that NF-κB protein level was low before infection (307.41 ± 37.35 pg/ml) and increased 2 times significantly after infection (585.88 ± 29.04 pg/ml) (p < 0.05). This evidence concerns the gene NFKB1 and infection.
