Effects of NK210 and NK219 on LPS-induced immune imbalance and cognitive impairment in mice. (A) Effects on colitis: colon length (a), myeloperoxidase (MPO) activity (b), IFN-γ (c), TNF-α (d), IL-10 expression (e), IFN-γ to IL-10 expression ratio (f), TNF-α to IL-10 expression ratio (g), and NF-κB+/CD11c+ cell population in the colon (h). (B) Effects on the immune imbalance: splenic NK cell cytotoxicity activities (a), peritoneal macrophage phagocytosis (b), IFN-γ (c), TNF-α, (d), and IL-10 expression (e), IFN-γ to IL-10 expression ratio (f), TNF-α to IL-10 expression ratio (g), Tbet (h) and Foxp3 expression (i), and Tbet to Foxp3 expression ratio (j) in the spleen. (C) Effects on cognitive impairment in the Y-maze (a) and NOR task (b). Effects on neuroinflammation: IFN-γ (c), TNF-α (d), IL-10 expression (e), IFN-γ to IL-10 expression ratio (f), TNF-α to IL-10 expression ratio (g), and BDNF+/NeuN+ and NF-κB+/Iba1+ cell populations (h) in the hippocampus. Test agents (LP, LPS alone; LR, 1 × 109 CFU/mouse/day of NK210; BL, 1 × 109 CFU/mouse/day of NK219; Mx, 1 × 109 CFU/mouse/day of LR and BL [4:1] mix) were orally gavaged daily for 5 days after intraperitoneal injection of LPS. Normal control mice (NC) were treated with vehicle (saline) instead of test agents. Data values indicate mean ± SD (n = 8). #p < 0.05 versus NC group. *p < 0.05 versus LP group treated with LPS alone.
