中风的特征是损伤周围区域的大量炎症,这会放大对大脑的损伤。肝脏X受体(LXRs)是调节胆固醇、脂质和葡萄糖代谢的核受体。合成的LXR激动剂在包括神经炎症在内的各种环境中具有有效的抗炎特性。然而,LXR激动剂抑制中风相关炎症的能力尚未得到评估。在这里,我们已经使用延时磁共振成像(MRI)显示,在急性脑缺血模型中,损伤后给予单剂量的LXR配体显著降低了脑损伤。神经保护与神经炎症抑制相关。
Stroke is characterized by massive inflammation in areas surrounding the injury that magnifies damage to the brain. The Liver X Receptors (LXRs) are nuclear receptors that regulate cholesterol, lipid, and glucose metabolism. Synthetic LXR agonists have potent anti-inflammatory properties in a variety of settings, including neuroinflammation. However, the ability of LXR agonists to suppress stroke-associated inflammation has not been evaluated. Here, we have used time-lapse magnetic resonance imaging (MRI) to show that a single dose of an LXR ligand administered post-injury dramatically reduces brain damage in a model of acute brain ischemia. Neuroprotection was associated with suppression of neuroinflammation.
