MetabolomicsToxoplasma gondii metabolic flexibility in response to iron deprivation

Iron is an essential nutrient for many critical cellular processes. As a consequence of diverse and dynamic host environments, the obligate intracellular parasite Toxoplasma gondii must adapt to iron limited conditions. To investigate the adaptations critical to parasite survival under these cond...

MetabolomicsThe Toxoplasma micropore mediates endocytosis for selective nutrient salvage from host cell compartments

Apicomplexan parasite growth and replication relies on nutrient acquisition from host cells, in which intracellular multiplication occurs, yet the mechanisms that underlie the nutrient salvage remain elusive. Numerous ultrastructural studies have documented a plasma membrane invagination with a d...

MetabolomicsPantothenate biosynthesis is critical for chronic infection by the neurotropic parasite Toxoplasma gondii
Coenzyme A (CoA) is an essential molecule acting in metabolism, post-translational modification, and regulation of gene expression. While all organisms synthesize CoA, many, including humans, are unable to produce its precursor, pantothenate. Intriguingly, like most plants, fungi and bacteria, paras...

MetabolomicsStable isotope labelling of Toxoplasma gondii under iron and copper restriction

Toxoplasma uses metal nutrients like iron and copper for vital functions in their energy metabolism. Here, we have used stable isotope labelling to track the incorporation of glucose and glutamine into metabolic pathways, primarily focusing on central carbon metabolism, when these metals are disr...

MetabolomicsLipidomic analysis of Toxoplasma gondii extracellular vesicles across host cell types

Introduction. Toxoplasma gondii is an obligate intracellular parasite with an exceptional capacity to colonize a broad range of host species and cell types. Successful infection depends on its ability to manipulate host metabolism, including lipid pathways that are essential for membrane biogenes...

MetabolomicsGlobal Metabolomic Profiling of Mice Brains following Experimental Infection with the Cyst-Forming Toxoplasma gondii
The interplay between the Apicomplexan parasite Toxoplasma gondii and its host has been largely studied. However, molecular changes at the metabolic level in the host central nervous system and pathogenesis-associated metabolites during brain infection are largely unexplored. We used a global metabo...

MetabolomicsMetabolomic signature of mouse cerebral cortex following Toxoplasma gondii infection

BACKGROUND: The protozoan parasite Toxoplasma gondii infects and alters the neurotransmission in cerebral cortex and other brain regions, leading to neurobehavioral and neuropathologic changes in humans and animals. However, the molecules that contribute to these changes remain l...

MetabolomicsSulfadiazine Sodium Improves Dysfunctional Metabolomics in Toxoplasma gondii-infected Mice
Toxoplasma gondii is an obligate intracellular protozoan parasite that poses a severe threat to human health, especially those immune-compromised individuals. Sulfadiazine sodium (SDZ) is widely used for the treatment of human toxoplasmosis. However, systems biology researches on the therapeutic eff...

MetabolomicsMetabolite profile of mice hippocampus following Toxoplasma gondii infection
Toxoplasma gondii is a protozoan parasite with a remarkable neuro-tropismneurotropic affinity. We recently showed that T. gondii infection can alter the global metabolism of the cerebral cortex of the mice. However, the impact of this infection on the metabolism of the hippocampus remains unclear. I...

MetabolomicsThe Toxoplasma monocarboxylate transporters are involved in the metabolism within the apicoplast and are linked to parasite survival

The apicoplast is a four-membrane plastid found in the apicomplexans, which harbors biosynthesis and organelle housekeeping activities in the matrix. However, the mechanism driving the flux of metabolites, in and out, remains unknown. Here we used TurboID and genome engineering to identify apicop...
