革兰氏阴性菌产生的脂多糖在神经退行性疾病的病理生理学中起着重要作用。大量证据表明,内毒素诱导的神经炎症与核因子-kappaB表达上调有关。在此,我们报告长期使用小剂量的脂多糖主要导致Id2蛋白表达上调。作为一种细胞分化抑制因子,Id2在成人嗅神经发生中起重要作用。然而,脑中的Id2蛋白就像一把剑,持续在脑内过度表达Id2可导致神经损伤,并可能与神经退行性变有关。
Lipopolysaccharide (LPS) from gram negative bacteria plays an important role in the pathophysiology of neurodegenerative diseases. Many evidences showed that LPS-induced neuroinflammation is related to upregulation of NF-kappaB. Here, we report that long-term treatment of lower dosage LPS mainly causes upregulation of Id2 protein. As an inhibitor of cell differentiation, Id2 plays an import role in adult olfactory neurogenesis. However, Id2 protein in brain acts as two edges in a sword, persist over-expression of Id2 in brain can induce neurodamages and may be related to neurodegeneration.
