Developmentally Regulated Sphingolipid Degradation in Leishmania major
Leishmania parasites alternate between extracellular promastigotes in sandflies and intracellular amastigotes in mammals. These protozoans acquire sphingolipids (SLs) through de novo synthesis (to produce inositol phosphorylceramide) and salvage (to obtain sphingomyelin from the host). A single ISCL (Inositol phosphoSphingolipid phospholipase C-Like) enzyme is responsible for the degradation of...
متن کاملSphingolipid Degradation in Leishmania (Leishmania) amazonensis
BACKGROUND Human leishmaniasis is caused by more than 20 Leishmania species and has a wide range of symptoms. Our recent studies have demonstrated the essential role of sphingolipid degradation in the virulence of Leishmania (Leishmania) major, a species responsible for localized cutaneous leishmaniasis in the Old World. In this study, we investigated the function of sphingolipid degradation in...
متن کاملDevelopmentally regulated sphingolipid synthesis in African trypanosomes.
Sphingolipids are essential components of eukaryotic membranes, and many unicellular eukaryotes, including kinetoplastid protozoa, are thought to synthesize exclusively inositol phosphorylceramide (IPC). Here we characterize sphingolipids from Trypanosoma brucei, and a trypanosome sphingolipid synthase gene family (TbSLS1-4) that is orthologous to Leishmania IPC synthase. Procyclic trypanosomes...
متن کاملA novel class of developmentally regulated noncoding RNAs in Leishmania.
Leishmania is a protozoan parasite that causes serious morbidity and mortality in humans worldwide. The ability of these parasites to survive within the phagolysosomes of mammalian macrophages is dependent on the developmental regulation of a variety of genes. Identifying genomic sequences that are preferentially expressed during the parasite's intracellular growth would provide new insights ab...
متن کاملCloning of developmentally regulated genes from Leishmania major and expression following heat induction.
The protozoa Leishmania undergo morphological and biochemical transformation from the promastigote to the amastigote form during their life cycle. To characterize this transformation process, we constructed a cDNA library for the promastigote stage of Leishmania major and used differential cDNA hybridization to identify cDNA sequences expressed at different abundance in promastigotes or amastig...
