Ultrastructural expansion microscopy reveals unexpected levels of glycosome heterogeneity in African trypanosomes

Journal of Microscopy, EarlyView.
Abstract Kinetoplastid parasites include several species. Trypanosoma brucei causes African sleeping sickness in humans and a wasting disease nagana in livestock. Trypanosoma cruzi is the causative agent of Chagas disease and Leishmania species cause leishmaniasis, which can present with visceral, cutaneous, or mucocutaneous symptoms.

New insights into Trypanosoma cruzi genetic diversity, and its influence on parasite biology and clinical outcomes

Frontiers in Immunology
Chagas disease, caused by Trypanosoma cruzi, remains a serious public health problem worldwide. The parasite was subdivided into six distinct genetic groups, called “discrete typing units” (DTUs), from TcI to TcVI. Several studies have indicated that the

Contribution of microscopy for understanding the mechanism of action against trypanosomatids [PDF]

, 2018
Transmission electron microscopy (TEM) has proved to be a useful tool to study the ultrastructural alterations and the target organelles of new antitrypanosomatid drugs.

Biochemical characterization of phosphoenolpyruvate carboxykinases from multiple species of brown algae

Journal of Phycology, EarlyView.
Abstract Phosphoenolpyruvate carboxykinase (PEPCK) is involved in the conversion of phosphoenolpyruvate (PEP) to oxaloacetate (OAA). In addition to playing a role in gluconeogenesis in various organisms, PEPCK also functions in the C4 cycle to concentrate CO2 for photosynthesis in some C4 plants.

Chronic Trypanosoma cruzi infection potentiates adipose tissue macrophage polarization toward an anti-inflammatory M2 phenotype and contributes to diabetes progression in a diet-induced obesity model [PDF]

, 2016
Chronic obesity and Chagas disease (caused by the protozoan Trypanosoma cruzi) represent serious public health concerns. The interrelation between parasite infection, adipose tissue, immune system and metabolism in an obesogenic context, has not been ...

Expanding an expanded genome: long-read sequencing of Trypanosoma cruzi

bioRxiv, 2018
Although the genome of Trypanosoma cruzi, the causative agent of Chagas disease, was first made available in 2005, with additional strains reported later, the intrinsic genome complexity of this parasite (abundance of repetitive sequences and genes ...

Potential geographic displacement of Chagas disease vectors under climate change

Medical and Veterinary Entomology, EarlyView.
As a result of modelling the potential distribution of 55 triatomine species in the Neotropical region, with climate change projected for up to 2050, we found no significant changes. With climate change projected for up to 2080 in the Neotropical region, we see a significant potential for the migration of 55 species of triatomines towards the Amazon ...

Discrete typing units of Trypanosoma cruzi identified in rural dogs and cats in the humid Argentinean Chaco [PDF]

, 2012
The discrete typing units (DTUs) of Trypanosoma cruzi that infect domestic dogs and cats have rarely been studied. With this purpose we conducted a cross-sectional xenodiagnostic survey of dog and cat populations residing in 2 infested rural villages in ...

Spontaneous dormancy protects Trypanosoma cruzi during extended drug exposure

bioRxiv, 2017
The ability of the Chagas disease agent Trypanosoma cruzi to resist extended in vivo exposure to highly effective trypanocidal compounds prompted us to explore the potential for dormancy and its contribution to failed drug treatments in this infection ...

Weight Loss‐Associated Remodeling of Adipose Tissue Immunometabolism

Obesity Reviews, EarlyView.
ABSTRACT Obesity is a multifactorial condition characterized by excessive adiposity and systemic chronic low‐grade inflammation. Recent literature reflects a growing appreciation for the complex interplay between metabolism and the immune system in the pathogenesis of obesity‐related health conditions.
