一般描述

25-羟基胆固醇是一种侧链取代的氧化胆固醇。Avanti独特的固醇可在小鼠体内逆转白内障。Gestwicki的团队......最终专注在化合物29上,这是一种天然存在于血液中但不存在于没有血液供应的晶状体中的类固醇。患有年龄相关性和遗传性白内障的小鼠右眼接受了滴眼液治疗,而左眼未接受治疗。当时在密歇根大学主导这项研究的Gestwicki说,经治疗的眼睛在仅仅几周后就明显清晰了。白内障的严重程度以0到4级来衡量,其中4级是最严重的情况。平均而言,此项研究中的小鼠在接受4周的治疗后,白内障的严重程度有大约一级的改善。Science DOI: 10.1126/Science.aad7400 近期研究表明,由微生物抗原所激活的巨噬细胞toll样受体(TLR)可诱导25-羟基胆固醇的合成,而这种氧化胆固醇可抑制IgA的生成。

Dysregulation of lipid metabolism is frequently associated with inflammatory conditions. The mechanism of this association is still not clearly defined. Recently, we identified a nuclear oxysterol, 25-hydroxycholesterol-3-sulfate (25HC3S), as an important regulatory molecule involved in lipid metabolism in hepatocytes. The

25-Hydroxycholesterol is produced in mammalian tissues. The function of this oxysterol is unknown. Here we describe a central role for 25-hydroxycholesterol in regulating the immune system. In initial experiments, we found that stimulation of macrophage Toll-like receptors (TLR) induced expression
