研究团队识别狼疮的潜在原因】领先的风湿病学家和费恩斯坦医学研究所医学博士Betty Diamond教授可能已将蛋白质鉴定为免疫系统对患有狼疮的患者的不良反应的原因。更好地了解免疫系统如何过度活跃将有助于更有效地治疗狼疮和潜在的其他自身免疫性疾病。这些发现发表在Nature Immunology。

狼疮是一种自身免疫性疾病,导致免疫系统丧失区分外来物质和健康组织的能力。它变得活动过度,攻击健康的组织,引起炎症和损伤关节,皮肤和内脏。以前的研究表明,基因PRDM1的多态性或变异是狼疮的危险因素。 PRDM1产生称为Blimp-1的蛋白质。在这项研究中,Diamond博士及其团队正在考察Blimp-1如何调节免疫系统。

“健康的免疫系统能够识别身体中不常见的生物体,并激活像T细胞这样的细胞来攻击它们,”Diamond博士说。 “在患有自身免疫性疾病如狼疮的患者中,免疫系统已经开始将健康细胞识别为目标。我们的研究发现,特定细胞类型中低水平的或不含Blimp-1蛋白质导致增加在蛋白CTSS中引起免疫系统识别健康细胞作为攻击的物质 - 特别是在女性中。

在动物模型中,Diamond博士的研究小组能够显示,Blimp-1水平下降的女性导致CTSS的增加,CTSS是一种有助于免疫系统看到微生物的蛋白质,也是导致疾病的微生物。这导致免疫系统攻击健康细胞。具有降低的Blimp-1水平的雄性动物显示其免疫系统没有变化。虽然需要更多的研究来确认风险基因PRDM1可能导致人类女性的过度活跃的免疫系统,这是更好地了解狼疮的原因和潜在治疗方法的重要发现。
