Gene Summary

Gene Summary

脂质运载蛋白2（LCN2），也称为中性粒细胞明胶酶相关脂质运载蛋白（NGAL），是一种由LCN2基因编码的分泌型蛋白质，属于脂质运载蛋白家族。该家族成员通常具有保守的β-桶状结构，能够结合和运输疏水性分子如脂质、类固醇和铁载体等。LCN2在先天免疫、炎症反应和铁代谢中发挥重要作用，尤其在细菌感染时通过螯合铁载体限制细菌生长。其主要作用位点包括肾脏、肝脏、脂肪组织和免疫细胞。LCN2突变可能导致其功能丧失，影响机体对感染的防御能力或铁代谢平衡，与多种疾病相关，如急性肾损伤（AKI）、慢性肾病（CKD）、肥胖相关代谢紊乱、某些癌症和炎症性疾病。LCN2过表达常见于炎症和损伤状态，可能加剧组织损伤或促进肿瘤进展，而降低表达可能削弱抗菌防御或影响铁稳态。在肾脏中，LCN2过表达是肾小管损伤的早期标志物，而在脂肪组织中，它与胰岛素抵抗和代谢综合征相关。脂质运载蛋白家族成员共享结合和转运小分子配体的能力，并参与多种生理和病理过程。LCN2作为该家族的重要成员，其表达水平变化可影响其他基因或通路，如通过调节铁代谢影响炎症反应或通过参与细胞凋亡和增殖影响组织修复。
