Liver X receptor
http://dbpedia.org/resource/Liver_X_receptor an entity of type: Thing
Les récepteurs des oxystérols ou liver X receptors LXRβ et LXRα, sont des protéines de la superfamille des récepteurs nucléaires liant naturellement les oxystérols et régulant le métabolisme du cholestérol et des lipides dans l'organisme ainsi que la réponse inflammatoire au niveau des macrophages. Leur rôle dans le développement de l'athérosclérose a été directement démontré.

肝X受体(英語:liver X receptor)是核受体超家族转录因子的一员,属于类的第一亚家族,同过氧化物酶体增殖物活化受体、类法尼醇x受体、有密切的联系。肝X受体的激素为氧化固醇,是胆固醇代谢的感受器。同时它还在脂肪形成、糖代谢、免疫与炎症反应等环节起到调节作用。 肝X受体有两个亚型被分辨出来,分别是肝X受体α与肝X受体β,根据核受体命名规则这两个亚型分别被命名为NR1H3(LXRα)与NR1H2(LXRβ)。肝X受体的两个亚型在1994、1995年间先后被分离出来。肝X受体α是由两个研究小组独立发现的,他们分别授予其RLD-1与LXR的名称。这两个亚型核受体结构相同,DNA结合域与配体结合域中有77%的氨基酸序列保持一致。肝X受体α主要在肝脏组织细胞中表达,胰脏、脾脏与小肠中也有所发现,而肝X受体β则可在全身各处细胞中检测到。

The liver X receptor (LXR) is a member of the nuclear receptor family of transcription factors and is closely related to nuclear receptors such as the PPARs, FXR and RXR. Liver X receptors (LXRs) are important regulators of cholesterol, fatty acid, and glucose homeostasis. LXRs were earlier classified as orphan nuclear receptors, however, upon discovery of endogenous oxysterols as ligands they were subsequently deorphanized.

The liver X receptor (LXR) is a member of the nuclear receptor family of transcription factors and is closely related to nuclear receptors such as the PPARs, FXR and RXR. Liver X receptors (LXRs) are important regulators of cholesterol, fatty acid, and glucose homeostasis. LXRs were earlier classified as orphan nuclear receptors, however, upon discovery of endogenous oxysterols as ligands they were subsequently deorphanized. Two isoforms of LXR have been identified and are referred to as LXRα and LXRβ. The liver X receptors are classified into subfamily 1 (thyroid hormone receptor-like) of the nuclear receptor superfamily, and are given the nuclear receptor nomenclature symbols NR1H3 (LXRα) and NR1H2 (LXRβ) respectively. LXRα and LXRβ were discovered separately between 1994-1995. LXRα isoform was independently identified by two groups and initially named RLD-1 and LXR, whereas four groups identified the LXRβ isoform and called it UR, NER, OR-1, and RIP-15. The human LXRα gene is located on chromosome 11p11.2, while the LXRβ gene is located on chromosome 19q13.3.
