Sm Antigen

Smith抗原(Sm-Ag)是四种可提取核抗原(ENA)的自身抗原之一,其他ENA分别为SS-A/Ro、SS-B/La和RNP。每个ENA由一个或多个与小核或细胞质RNA物种(snRNP)相关的蛋白质组成,snRNP的大小从80到350个核苷酸不等。ENA抗体常见于结缔组织病患者,包括红斑狼疮(LE)、混合结缔组织病、干燥综合征、硬皮病和多发性肌炎/皮肌炎。抗Sm几乎只在狼疮患者中发现,约20%的病例中出现抗Sm,发病率因种族而异。它在健康人中的发病率低于1%,在患有其他风湿性疾病的人群中很少出现。抗Sm抗体通常通过ELISA、反向免疫电泳(CIE)、免疫扩散或血凝来检测。
