Abstract

Neutral monohexosylceramides (CMHs) globosides (globotriasyl ceramides), other glycosphingolipids (GSLs) and more complex structures such as glycoinositol-phospholipids(GIPLs) and glycosyl phosphatidylinositol (GPI) anchors have been described in several members of the trypanosomatid family. These highly bioactive molecules are not only components of biological structures but also participants in host-parasite interactions such as macrophage invasion, anti- genic presentation and signal transduction. Glycolipid structures have been studied using mass spectrometry (MS).This review describes a wide range of glycoconjugates with unique and complex structures that are present in several trypano- somatid species. Their structures are described in the context of their biological significance.

锥虫体内发现的糖脂结构:对寄生虫功能的贡献
中性单己基神经酰胺(CMHs)、球苷(globotriasyl神经酰胺)、其他糖鞘脂(GSLs)和更复杂的结构,如糖肌醇-磷脂(GIPLs)和糖基磷脂酰肌醇(GPI)锚定物,已经在锥虫家族的一些成员中被描述。这些具有高度生物活性的分子不仅是生物结构的组成部分,而且还参与宿主-寄生虫相互作用,如巨噬细胞入侵,抗基因递呈和信号转导。用质谱法(MS)研究了糖脂结构。本文综述了存在于几种锥虫-体虫物种中具有独特和复杂结构的广泛的糖缀合物。它们的结构是根据它们的生物学意义来描述的。
