系统性红斑狼疮(SLE)是一种异质性自身免疫性疾病。虽然其病因仍然难以捉摸,但目前的理解表明这是一个多因素过程,其中包括遗传、免疫、激素和环境因素。结合了其中几个因素的假设提出,基因组元件 L1 逆转录转座子在 SLE 发病机制中发挥着重要作用。 L1 逆转录元件在 SLE 中被转录激活,产生两种蛋白质 ORF1p 和 ORF2p,它们具有免疫原性,可以通过产生激活胞质 DNA 传感器的 DNA 种类来驱动 I 型干扰素 (IFN) 的产生。此外,这两种蛋白质存在于富含 RNA 的大分子组装体中,其中还含有众所周知的 SLE 自身抗原,如 Ro60。我们推测表达 L1 的细胞将表现出病毒感染细胞的所有特征,从而产生与慢性病毒感染相似的细胞和体液免疫反应。然而,与外源病毒不同,L1 逆转录元件不能从宿主基因组中消除。因此,L1 失调将对免疫系统造成慢性但可能是偶发性的挑战。该模型至少可以部分解释 SLE 的临床和免疫学特征。在这里,我们回顾了 SLE 这一假说的支持和差距,及其为 SLE 提供新的诊断、预后和治疗选择的潜力。
Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease. While its etiology remains elusive, current understanding suggests a multifactorial process with contributions by genetic, immunologic, hormonal, and environmental factors. A hypothesis that combines several of these factors proposes that genomic elements, the L1 retrotransposons, are instrumental in SLE pathogenesis. L1 retroelements are transcriptionally activated in SLE and produce two proteins, ORF1p and ORF2p, which are immunogenic and can drive type I interferon (IFN) production by producing DNA species that activate cytosolic DNA sensors. In addition, these two proteins reside in RNA-rich macromolecular assemblies that also contain well-known SLE autoantigens like Ro60. We surmise that cells expressing L1 will exhibit all the hallmarks of cells infected by a virus, resulting in a cellular and humoral immune response similar to those in chronic viral infections. However, unlike exogenous viruses, L1 retroelements cannot be eliminated from the host genome. Hence, dysregulated L1 will cause a chronic, but perhaps episodic, challenge for the immune system. The clinical and immunological features of SLE can be at least partly explained by this model. Here we review the support for, and the gaps in, this hypothesis of SLE and its potential for new diagnostic, prognostic, and therapeutic options in SLE.
