Nur 77是在人类动脉粥样硬化中表达的孤儿核受体。在体外的血管细胞中,Nur 77的表达是由促炎因子如氧化LDL(oxLDL)诱导的。我们分析了Nur 77在oxLDL诱导的巨噬细胞分化为树突状细胞(DC)中的作用。鼠RAW264.7巨噬细胞系用编码GFP或GFP与全长Nur 77(GFP-Nur 77)、缺乏DNA结合结构域的Nur 77(GFP-Nur 77-ΔDBD)或缺乏反式激活结构域的Nur 77(GFP-Nur 77-Δ DBD)的融合物的表达质粒稳定转染。 对GFP-Nur 77-Δ DBD和GFP-Nur 77-ΔDBD的分析表明,Nur 77 DNA结合结构域和反式激活结构域都是这种效应所必需的。GFP-Nur 77-ΔDBD始终具有与GFP-Nur 77相反的作用,在所有测定中增加DC型分化。有趣的是,GFP-Nur 77-ΔDBD蛋白是胞质的,而GFP-Nur 77和GFP-Nur 77-Δ DBD蛋白都是核的。这些数据显示GFP-Nur 77抑制oxLDL处理的巨噬细胞分化为DC。Nur 77对巨噬细胞表型的影响可能涉及其亚细胞分布的变化。
Nur77 is an orphan nuclear receptor expressed in human atheroma. In vascular cells in vitro, Nur77 expression is induced by pro-inflammatory factors, such as oxidized LDL (oxLDL). We analyze the role of Nur77 in the oxLDL-induced differentiation of macrophages into dendritic cells (DC). The murine RAW264.7 macrophage cell line was stably transfected with expression plasmids encoding either GFP or GFP fusions with either full-length Nur77 (GFP-Nur77), Nur77 lacking the DNA binding domain (GFP-Nur77-ΔDBD) or Nur77 lacking the transactivation domain (GFP-Nur77-ΔTAD). Analysis of GFP-Nur77-ΔTAD and GFP-Nur77-ΔDBD indicated that the Nur77 DNA binding and transactivation domains were both required for this effect. GFP-Nur77-ΔDBD consistently had the opposite effect to GFP-Nur77, increasing DC-type differentiation in all assays. Interestingly, GFP-Nur77-ΔDBD protein was cytosolic, whereas GFP-Nur77 and GFP-Nur77-ΔTAD were both nuclear. These data show that GFP-Nur77 inhibited differentiation of oxLDL-treated macrophages into DC. The effects of Nur77 on the macrophage phenotype may involve changes in its subcellular distribution.
