免疫系统在大脑发育中起着至关重要的作用。全球 70% 以上的新生儿接种了乙型肝炎疫苗 (HBV)。这种新生儿疫苗接种是否会影响大脑发育尚不清楚。新生 C57BL/6 小鼠腹腔注射 HBV 或磷酸盐缓冲盐水。 HBV 在 8 周龄时引起行为表现受损和海马长时程增强,但在 4 周或 12 周龄时没有影响。 6 周时,接种 HBV 疫苗的小鼠海马神经发生、M1 小胶质细胞激活减少,神经免疫分子表达的神经毒性特征 [肿瘤坏死因子-α 增加,干扰素 (IFN)-γ、脑源性神经营养因子和胰岛素样生长因子-1 减少]。在血清中,HBV 诱导白细胞介素 (IL)-4 水平显着升高,表明存在 T 辅助细胞 (Th)-2 偏差。此外,在个体水平上,血清IFN-γ/IL-4比值与神经营养素水平和海马神经发生呈正相关。这些发现表明,新生小鼠接种 HBV 疫苗后,会在海马体中诱导促炎性和低神经营养环境,从而导致成年早期的神经行为损伤,而这种环境遵循 HBV 诱导的系统性 Th2 偏向。
The immune system plays a vital role in brain development. The hepatitis B vaccine (HBV) is administered to more than 70% of neonates worldwide. Whether this neonatal vaccination affects brain development is unknown. Newborn C57BL/6 mice were injected intraperitoneally with HBV or phosphate-buffered saline. HBV induced impaired behavioral performances and hippocampal long-term potentiation at 8 weeks (w) of age without influence at 4 or 12 w. At 6 w, there was decreased neurogenesis, M1 microglial activation and a neurotoxic profile of neuroimmune molecule expression [increased tumor necrosis factor-α and reduced interferon (IFN)-γ, brain-derived neurotrophic factor and insulin-like growth factor-1] in the hippocampus of the HBV-vaccinated mice. In the serum, HBV induced significantly higher levels of interleukin (IL)-4, indicating a T helper (Th)-2 bias. Moreover, the serum IFN-γ/IL-4 ratio was positively correlated with the levels of neurotrophins and neurogenesis in the hippocampus at the individual level. These findings suggest that neonatal HBV vaccination of mice results in neurobehavioral impairments in early adulthood by inducing a proinflammatory and low neurotrophic milieu in the hippocampus, which follows the HBV-induced systemic Th2 bias.
