抗neun抗体已被广泛使用超过15年,用于明确识别多种脊椎动物(包括小鼠、大鼠和人类)中枢神经系统中的有丝分裂后神经元。与广泛报道的核定位相反,我们发现,与对照组相比,认知障碍hiv感染者脑切片神经元细胞质中的NeuN反应性明显更高。抗neun抗血清的蛋白靶点最近被确定为神经元特异性RNA剪接因子Rbfox3,但其在影响大脑的疾病中的意义此前尚未报道。RNA剪接发生在细胞核中,因此RbFox3在细胞质中的定位改变可能导致神经元基因表达下调。
The anti-NeuN antibody has been widely used for over 15 years to unambiguously identify post-mitotic neurons in the central nervous system of a wide variety of vertebrates including mice, rats and humans. In contrast to its widely reported nuclear localization, we found significantly higher NeuN reactivity in the cytoplasm of neurons in brain sections from HIV-infected individuals with cognitive impairment compared to controls. The protein target of anti-NeuN antisera was recently identified as the neuron-specific RNA splicing factor, Rbfox3, but its significance in diseases affecting the brain has not been previously reported. RNA splicing occurs in the nucleus hence, the altered localization of RbFox3 to the cytoplasm may lead to the downregulation of neuronal gene expression.
