摘要 | Our previous work demonstrated that neuroinflammation evoked by triple repeated central LPS challenges inhibited adult hippocampal neurogenesis that were correlated with the depressive-like behavioral symptoms induced by neuroinflammation. These findings suggest that hippocampal neurogenesis might be one of biological mechanisms underlying depression induced by neuroinflammation and targeting neurogenesis might lead to new therapeutic strategies for the treatment of depression. In this study, we manipulated adult hippocampal neurogenesis using fibroblast growth factor 2 (FGF2), one crucial molecule modulating cell proliferation and survival in central nervous system, and investigate the involvement and the potential therapeutic effects of FGF2 on neuroinflammation-induced depression. Central lipopolysaccharides (LPS) challenges were used as previously to evoke the neuroinflammatory state in the brain of rat. Exogenous FGF2 was infused into lateral ventricle during the neuroinflammatory state. It was found that the protein expression of FGF2 in hippocampus was inhibited by neuroinflammation. The activation of extracellular signal-regulated kinase (ERR), the downstream molecule of FGF2, was also inhibited by neuroinflammation. Exogenous FGF2 infusions prevented the decrease in phosphorylation of ERK1/2 under neuroinflammation state. Exogenous FGF2 reversed depressive-like behaviors and the impaired hippocampal neurogenesis induced by neuroinflammation. These findings provide evidence that the FGF2-ERK1/2 pathway is involved in the pathophysiology of depressive-like behaviors, and manipulating the neurogenesis pathway is a viable therapeutic approach to inflammation-associated depression.
