本综述重点关注狼疮性肾炎患者的致病分子和转录事件。这些因素是肾 DNaseI、暴露的染色质片段和相应的染色质反应性自身抗体。狼疮性肾炎是人类系统性红斑狼疮最严重的并发症,其特征是染色质片段-IgG复合物在系膜基质和肾小球基底膜沉积。后者的沉积定义为终末期疾病。该事件与 DNaseI 基因表达的肾脏限制性关闭密切相关,这通过 DNaseI mRNA 水平和 DNaseI 酶活性的丧失来确定。本综述的主要目的是基于对疾病发病机制的新见解来制定新的治疗策略。
The present review focuses on pathogenic molecular and transcriptional events in patients with lupus nephritis. These factors are renal DNaseI, exposed chromatin fragments and the corresponding chromatin-reactive autoantibodies. Lupus nephritis is the most serious complication in human systemic lupus erythematosus, and is characterised by deposition of chromatin fragment-IgG complexes in the mesangial matrix and glomerular basement membranes. The latter deposition defines end-stage disease. This event is stringently linked to a renal-restricted shutdown of expression of the DNaseI gene, as determined by loss of DNaseI mRNA level and DNaseI enzyme activity. The major aim of the present review is to generate new therapeutic strategies based on new insight into the disease pathogenesis.
