(A) Schematic of the experimental design showing AZD1480 and LPS interventions in UL mice. (B, C) In the open field test, there were no significant differences in total movement distance and average speed among the four groups of mice: UL + Static + VH, UL + Static + AZD1480, UL + Run + VH, UL + Run + LPS (One‐way ANOVA: F (3,36) = 1.236, p = 0.3110, and F (3,36) = 1.257, p = 0.3037). (D, E) There were no significant intergroup differences in terms of total immobility time and the duration spent in the central zone of the open field for the UL + Static + VH, UL + Static + AZD1480, UL + Run + VH, UL + Run + LPS groups (One‐way ANOVA: F (3,36) = 1.780, p = 0.1684 and F (3,36) = 0.7831, p = 0.5112, n = 10/group in OFT). (F, G) AZD1480 ameliorated the UL‐induced working memory impairment, whereas LPS counteracts the cognitive improvements conferred by running, manifested by the total entry to and time spent in the novel arm. Right arm (F) was set as the novel arm (One‐way ANOVA: F (3,36) = 9.760, p < 0.0001), Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p = 0.0011, UL + Static + VH vs. UL + Run + VH: p = 0.0036, UL + AZD1480 vs. UL + Run + LPS: p = 0.0022, UL + Run + VH vs. UL + Run + LPS: p = 0.0068 for the percentage of novel arms; One‐way ANOVA: F (3,36) = 15.93, p < 0.0001, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p < 0.0001, UL + AZD1480 vs. UL + Run + VH: p = 0.0056, UL + Static + AZD1480 vs. UL + Run + LPS: p < 0.0001 for the total time of the novel arms, Left arm (G) was set as the novel arms (One‐way ANOVA: F (3,36) = 2.814, p = 0.0529, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Run + VH p = 0.0488, for the percentage of novel arms; One‐way ANOVA: F (3,36) = 7.771, p = 0.0004, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p = 0.0036, UL + Static + VH vs. UL + Run+ VH: p = 0.0005 for the total time of the novel arms, n = 10/group in T maze).

(L, M) AZD1480 and running resulted in improved contextual and tone‐cued fear conditioning, but LPS prevented the running‐induced improvement (One‐way ANOVA: F (3,36) = 17.34, p < 0.0001, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p < 0.0001, UL + Static + VH vs. UL + Run + VH: p = 0.0017, UL + Static + AZD1480 vs. UL + Run + LPS: p < 0.0001, UL + Run + VH vs. UL + Run + LPS: p < 0.0001.

(H) AZD1480 significantly improves the number of errors in UL‐induced reference memory, whereas LPS counteracts the cognitive improvements conferred by running (two‐way ANOVA: F (27,324) = 2.115, p = 0.0013, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p < 0.0001, UL + Static + VH vs. UL + Run + VH: p < 0.0001, UL + Static + AZD1480 vs. UL + Run + LPS: p < 0.0001, UL + Run + VH vs. UL + Run + LPS: p < 0.0001). (I) AZD1480 significantly reduces the number of errors in working memory induced by UL (two‐way ANOVA: F (27,324) = 1.623, p = 0.0283, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p < 0.0001, UL + Static + VH vs. UL + Run + VH: p = 0.0273, UL + Static + AZD1480 vs. UL + Run + LPS: p = 0.0006). (J) Total time to complete tasks decreased by aerobic exercise (two‐way ANOVA: F (27,324) = 3.394, p < 0.0001), Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p = 0.0003, UL + Static + VH vs. UL + Run + VH: p = 0.0003, UL + Static + AZD1480 vs. UL + Run + LPS: p = 0.0001, UL + Run + VH vs. UL + Run + LPS: p = 0.0001, n = 10/group, data are presented as mean ± standard error of the mean (SEM). (K) Throughout the training, UL + Static + VH, UL + Static + AZD1480, UL + Run + VH and UL + Run + LPS mice froze at comparable level during the trace interval (two‐way ANOVA, F (3,72) = 0.5261, p = 0.6658). (L, M) AZD1480 and running resulted in improved contextual and tone‐cued fear conditioning, but LPS prevented the running‐induced improvement (One‐way ANOVA: F (3,36) = 17.34, p < 0.0001, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p < 0.0001, UL + Static + VH vs. UL + Run + VH: p = 0.0017, UL + Static + AZD1480 vs. UL + Run + LPS: p < 0.0001, UL + Run + VH vs. UL + Run + LPS: p < 0.0001.

Article Snippet: At 2 weeks after UL induction, mice received daily oral gavage of either AZD1480 (HY‐10193, MCE) at 25 mg/kg or a vehicle (VH) control consisting of 0.1% dimethyl sulfoxide (DMSO; HY‐Y0320, MCE) [ ].

Figure Lengend Snippet: AZD1480 rescues the UL‐mediated suppression of hippocampal neurogenesis, while LPS markedly attenuates the pro‐proliferative effects of running. (A) Representative images showing BrdU+ and DAPI+ cells in the DG. (B) AZD1480 increases the number of BrdU+ cells induced by UL, while LPS counteracts the neuroproliferative effects induced by running. (One‐way ANOVA: F (3,36) = 21.29, p < 0.0001, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p = 0.0001, UL + Static + VH vs. UL + Run + VH: p < 0.0001, UL + Static + AZD1480 vs. UL + Run + LPS: p = 0.0094, UL + Run + VH vs. UL + Run + LPS: p < 0.0001). (C) Representative images showing Ki67+ and DAPI+ cells in the DG. (D) Running increases the number of UL‐induced Ki67+ cells, while AZD1480 and LPS have no significant effect on Ki67+ cell counts. (One‐way ANOVA: F (3,36) = 4.058, p = 0.0139, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Run + VH: p = 0.0092). (E) Representative images showing DCX+ and DAPI+ cells in the DG. (F) AZD1480 increases the number of DCX+ cells induced by UL, while LPS counteracts the neuroproliferative effects induced by running. (One‐way ANOVA: F (3,36) = 10.35, p < 0.0001, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p = 0.0007, UL + Static + VH vs. UL + Run + VH: p < 0.0001, UL + Run + VH vs. UL + Run + LPS: p = 0.0490). (G) Representative photomicrographs of the dendritic branches of GFP+ cells in the DG. GFP+ cells were labeled with retrovirus pROVEF1a‐EGFP, which was injected in the DG. (H) AZD1480 significantly increases the total number of dendritic branches in individual GFP + newborn neurons induced by UL. (One‐way ANOVA: F (3,28) = 12.20, p < 0.0001, Tukey's multiple comparisons test: UL + Static + VH vs. UL + Static + AZD1480: p = 0.0012, UL + Static + VH vs. UL + Run + VH < 0.0001, UL + Static + VH vs. UL + RUN + LPS: p = 0.0020).
