| 描述 | 核斑点染色程度有显着差异，G2期染色最强，G1期最弱或无染色。着丝粒体在前中期和分裂中期细胞内呈阳性，展现出多颗排列整齐但小而微弱的色点。前中期细胞多数呈现微弱的核被膜染色。有些血清样本在分裂后期和末期的子细胞分裂中区环 (即中间体，茎体) 则有强烈染色。分裂期细胞的细胞质有广泛染色。 |
Nuclear speckled pattern with striking variability in intensity with the strongest staining in G2 phase and weakest/negative staining in G1. The centromeres are positive only in prometaphase and metaphase, revealing multiple aligned small and faint dots. Prometaphase cells frequently show a weak staining of the nuclear envelope. During anaphase and telophase, some sera demonstrate intense staining in the ring located at the midzone (i.e. mid-body, stem body) where the division of the daughter cells is taking place. The surrounding cytoplasm of the mitotic cells is diffusely stained. |

►大多数表现出AC-14核型的血清来自具有多种肿瘤病症（乳腺癌，肺癌，结肠癌，淋巴瘤，卵巢癌，脑癌）的患者；矛盾的是，患有这些恶性肿瘤的患者中出现AC-14核型的概率很低。
► AC-14核型也可见于炎症性疾病(克罗恩病、自身免疫性肝病、干燥综合征、移植物抗宿主病)；目前关于临床相关性的信息主要基于病例报告和一系列病例结果。
►只有在抗原特异性免疫实验中证实了对着丝点蛋白F有反应时，才能证明与其存在联系；目前关于临床相关性的信息主要基于病例报告和一系列病例结果；该自身抗体的特异性免疫检测目前尚无商品化试剂（74-78）。
► The majority of sera exhibiting the AC-14 pattern are from patients with a diversity of neoplastic conditions (breast, lung, colon, lymphoma, ovary, brain); paradoxically, the frequency of the AC-14 pattern in patient cohorts with these malignancies is low
► The AC-14 pattern is also seen in inflammatory conditions (Crohn’s disease, autoimmune liver disease, SjS, graft-versus-host disease); current information on clinical associations is based mainly on case reports and series of cases
► Possible associations only hold if the reactivity to CENP-F is confirmed in an antigen-specific immunoassay; current information on clinical associations is based mainly on case reports and series of cases; specific immunoassays for this autoantibody are currently not commercially available (74–78)
