Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Molecular and antigenic characterization of Trypanosoma cruzi TolT proteins [PDF]

, 2018
Background: TolT was originally described as a Trypanosoma cruzi molecule that accumulated on the trypomastigote flagellum bearing similarity to bacterial TolA colicins receptors.

A new piece in the repeatome puzzle of Triatominae bugs: The analysis of Triatoma rubrofasciata reveals the role of satellite DNAs in the karyotypic evolution of distinct lineages

Insect Molecular Biology, EarlyView.
Satellite DNAs comprise the major component of the Triatoma rubrofasciata repeatome, highlighting their central role in genome composition and architecture. Satellite DNA families show recent amplification in heterochromatin and older, more divergent satellite DNAs located in euchromatin, indicating distinct evolutionary histories.

Interaction of Trypanosoma cruzi, Triatomines and the Microbiota of the Vectors—A Review

Microorganisms
This review summarizes the interactions between Trypanosoma cruzi, the etiologic agent of Chagas disease, its vectors, triatomines, and the diverse intestinal microbiota of triatomines, which includes mutualistic symbionts, and highlights open questions.

Prevalence and Transmission of Trypanosoma cruzi in People of Rural Communities of the High Jungle of Northern Peru.

PLoS Neglected Tropical Diseases, 2015
BackgroundVector-borne transmission of Trypanosoma cruzi is seen exclusively in the Americas where an estimated 8 million people are infected with the parasite. Significant research in southern Peru has been conducted to understand T. cruzi infection and

Biotic Assembly of the Species of Triatomini (Hemiptera: Reduviidae: Triatominae) in the Mexican and South American Transition Zones

Journal of Biogeography, EarlyView.
ABSTRACT Aim To infer the biogeographic history of the Triatomini by evaluating how their species became part of the biogeographic transition zones of the New World. This group of blood‐feeding insects includes key vectors of Chagas disease. Understanding their dispersal and diversification over geological time may help elucidate the temporal dynamics ...

Immune complexes in chronic Chagas disease patients are formed by exovesicles from Trypanosoma cruzi carrying the conserved MASP N-terminal region [PDF]

, 2017
The exovesicles (EVs) are involved in pathologic host-parasite immune associations and have been recently used as biomarkers for diagnosis of infectious diseases.

Artificial intelligence‐powered microscopy: Transforming the landscape of parasitology

Journal of Microscopy, EarlyView.
Abstract Microscopy and image analysis play a vital role in parasitology research; they are critical for identifying parasitic organisms and elucidating their complex life cycles. Despite major advancements in imaging and analysis, several challenges remain. These include the integration of interdisciplinary data; information derived from various model

Evidence of meaningful levels of Trypanosoma cruzi in platelet concentrates from seropositive blood. [PDF]

, 2015
BACKGROUND: According to the reported cases of transfusion-acquired Trypanosoma cruzi infection, the risk of T. cruzi transfusion transmission appears to be higher with platelet (PLT) products than with other blood components.
