摘要
鞘脂是细胞膜脂质双层的主要结构成分并调控细胞重要生理功能,其代谢异常与多种慢性疾病密切相关。细胞鞘脂代谢以神经酰胺为中心,包括神经酰胺从头合成以及复杂鞘脂降解为神经酰胺等。近年来研究发现胰岛素抵抗的肥胖患者存在鞘脂代谢异常,而神经酰胺等鞘脂堆积可通过多种机制导致胰岛素抵抗。文中就近来鞘脂代谢异常和肥胖相关的胰岛素抵抗研究进展作一综述。
Sphingolipids are essential components of cellular membrane , regulating important physiologic function of cells .Al-terations of sphingolipid metabolism are closely related to the pathogenesis of several chronic diseases .Ceramide biogenesis , the center of sphingolipid metabolism , includes de novo ceramide synthesis , ceramide formation via breakdown of complicated sphingolipids and so on . Recent studies found that aberrant sphingolipid metabolism is strongly linked to insulin resistance associated with obesity .The review fo-cuses on recent advances about aberrant sphingolipid metabolism in the pathogenesis of insulin resistance associated with obesity .
