Abstract

Eukaryotic cells have distinct membrane-enclosed organelles, each with a unique biochemical signature and specialized function. The unique identity of each organelle is greatly governed by the asymmetric distribution and regulated intracellular movement of two important biomolecules, lipids, and proteins. Non-vesicular lipid transport mediated by lipid-transfer proteins (LTPs) plays essential roles in intra-cellular lipid trafficking and cellular lipid homeostasis, while vesicular transport regulates protein trafficking. A comparative analysis of non-vesicular lipid transport machinery in protists could enhance our understanding of parasitism and basis of eukaryotic evolution. , the trypanosomatid parasite, greatly depends on receptor-ligand mediated signalling pathways for cellular differentiation, nutrient uptake, secretion of virulence factors, and pathogenesis. Lipids, despite being important signalling molecules, have intracellular transport mechanisms that are largely unexplored in . We have identified a repertoire of sixteen (16) potential lipid transfer protein (LTP) homologs based on a domain-based search on TriTrypDB coupled with bioinformatics analyses, which signifies the presence of well-organized lipid transport machinery in this parasite. We emphasized here their evolutionary uniqueness and conservation and discussed their potential implications for parasite biology with regards to future therapeutic targets against visceral leishmaniasis.

摘要

真核细胞具有独特的膜包裹细胞器,每个细胞器都具有独特的生化特征和专门的功能。每个细胞器的独特身份在很大程度上受到两种重要生物分子,脂质和蛋白质的不对称分布和调节细胞内运动的控制。脂质转移蛋白 (LTP) 介导的非囊泡脂质运输在细胞内脂质运输和细胞脂质动态平衡中起着重要作用,而囊泡运输则调节蛋白质运输。对原生动物中非囊泡脂质运输机制的比较分析可以增强我们对寄生和真核进化基础的理解。 ,一种寄生性原生动物,在细胞分化、营养物质摄取、毒力因子分泌和发病机制方面,极大地依赖于受体-配体介导的信号通路。尽管脂质是重要的信号分子,但它们的细胞内运输机制在很大程度上尚未在 中得到探索。我们已经基于 TriTrypDB 上的基于结构域的搜索和生物信息学分析,确定了十六(16)种潜在的脂质转移蛋白 (LTP) 同源物,这表明该寄生虫中存在组织良好的脂质运输机制。我们在这里强调了它们的进化独特性和保守性,并讨论了它们在针对内脏利什曼病的未来治疗靶标方面对寄生虫生物学的潜在意义。
