同义词 核膜孔 Nuclear membrane pores
描述

间期细胞核膜呈现颗粒状荧光,临近细胞相触部位的荧光增强。分裂中期和后期细胞的染色体阴性。例如抗gp210抗体。

Nuclear envelope reveals a punctate staining in interphase cells, with accentuation of fluorescence at the points where adjacent cells touch each other. No staining of the metaphase and anaphase chromatin plates. e.g. anti-gp210.

抗原相关性 核孔复合蛋白(例如,gp210) nuclear pore complex proteins (i.e. gp210)

►发现于原发性胆汁性胆管炎患者,以及其他自身免疫性肝病和系统性自身免疫性风湿疾病患者

►如临床怀疑为原发性胆汁性胆管炎,建议随访检测抗gp210抗体;该抗原包含在疾病特异性免疫测定试剂中(例如,扩展的自免肝抗体谱)(62-64)

►其他被识别的抗原包括p62核孔蛋白、LBR和Tpr;目前还没有针对这些自身抗体的特异性免疫检测商品化试剂盒(65-68)

*实用的炎症性肌病谱、系统性硬化症谱和自免肝抗体谱(扩展版)检测可能仅限于专业的临床实验室。


► Found in patients with PBC, as well as patients with other autoimmune liver diseases and SARD (61)

► If PBC is clinically suspected, it is recommended to perform a follow-up test for anti-gp210 antibodies; the antigen is included in disease specific immunoassays (i.e., extended liver profile*) (62–64)

► Other antigens recognized include p62 nucleoporin, LBR, and Tpr; specific immunoassays for these autoantibodies are currently not commercially available (65–68)

*Availability of the inflammatory myopathy profile, the SSc profile and the (extended) liver profile may be limited to specialty clinical laboratories.

二级信息 Second level information

抗p62核孔蛋白抗体见于原发性胆汁性胆管炎和系统性红斑狼疮(23-24)

LBR抗体见于原发性胆汁性胆管炎(25)

►抗Tpr抗体见于原发性胆汁性胆管炎、自身免疫性肝病、系统性红斑狼疮、系统性硬化症和干燥综合征(26)

注意:大多数报告都描述了直接结合特定抗原的自身抗体(例如,抗原特异性免疫检测),实际上并没有显示出与AC-12核型的明确关联;目前还没有针对这些自身抗体的特异性免疫检测商品化试剂。


► Anti‐p62 nucleoporin antibodies have been described in PBC and SLE (23, 24)

► Anti‐LBR antibodies have been described in PBC (25)

► Anti‐Tpr antibodies have been described in PBC, autoimmune liver disease, SLE, SSc and SjS (26)

Notes: Most reports describe autoantibodies directly binding to specific antigens (i.e., antigen‐specific immunoassays) and do not actually show clear correlations with the AC‐12 pattern as such; specific immunoassays for these autoantibodies are currently not commercially available.
