AC-15-胞浆线性/肌动蛋白型

同义词 肌动蛋白类 actin-like
描述

此模式的特征是细胞骨架纤维染色，有时像细小间断的粒状沉积物。典型染色是纹状肌动蛋白链贯穿细胞的长轴。例如抗肌动蛋白抗体，抗非肌细胞肌球蛋白抗体。

 This pattern is characterized by decorated cytoskeletal fibers, sometimes with small, discontinuous granular deposits. Typical staining show striated actin cables spanning the long axis of the cells. e.g. anti-actin, anti-non-muscle myosin.
抗原相关性 肌动蛋白，非肌细胞肌球蛋白 actin, non-muscle myosin

  • ►在1型自身免疫性肝炎、慢性HCV感染，以及乳糜泻 (IgA亚型)患者中检出；在系统性自身免疫性风湿疾病中极为罕见 (17)

    ►如果临床上疑似为1型自身免疫性肝炎，推荐确认平滑肌抗体的反应性 (IgG亚型)，通常可通过基于啮齿动物组织 (肝、胃、肾) 的间接免疫荧光法进行检测；抗平滑肌抗体已被纳入1型自身免疫性肝炎的国际标准 (17, 80)

    ►F肌动蛋白 (F-actin) 是1型自身免疫性肝炎中抗平滑肌抗体的主要靶抗原；F肌动蛋白的自身抗体比G肌动蛋白(G-actin) 抗体更具临床意义 (81-83)

    注：尽管抗F肌动蛋白的免疫检测试剂已经商品化，但还应考虑到与这些免疫检测分析的敏感性有关的技术问题。


    ► Found in patients with AIH type 1, chronic HCV infection, and celiac disease (IgA isotype); rare in SARD (17)

    ► If AIH type 1 is clinically suspected, it is recommended to confirm reactivity with smooth muscle antibodies (IgG isotype), typically detected by IIFA on rodent tissue (liver, stomach, kidney); anti-smooth muscle antibodies are included in the international criteria for AIH type 1 (17,80)

    ► F-actin is the main target antigen of anti-smooth muscle antibodies in AIH type 1; autoantibodies to F-actin are of more clinical importance than antibodies to G-actin (81–83)

    Notes: Although anti-F-actin immunoassays are commercially available, technical issues relating to the sensitivity of these immunoassays should be taken into consideration.
