Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Multiple evolutionary origins of Trypanosoma evansi in Kenya.

PLoS Neglected Tropical Diseases, 2017
Trypanosoma evansi is the parasite causing surra, a form of trypanosomiasis in camels and other livestock, and a serious economic burden in Kenya and many other parts of the world.

Evidence for regulated expression of Telomeric Repeat-containing RNAs (TERRA) in parasitic trypanosomatids [PDF]

, 2017
The Telomeric Repeat-containing RNAs (TERRA) participate in the homeostasis of telomeres in higher eukaryotes. Here, we investigated the expression of TERRA in Leishmania spp.

Ruthenium‐Catalyzed CH Alkenylation of Trypanocidal Naphthoquinones: A Mechanistic Benchmarking Study

ChemistryOpen, EarlyView.
Computational roadmap to click‐ready quinones. Quantum chemical analysis reveals how substituents modulate the reactivity of trypanocidal naphthoquinones in Ru‐catalyzed CH alkenylation, guiding the design of sulfonyl‐fluoride scaffolds for next‐generation antiparasitic agents.

Trypanosoma cruzi expresses a plant-like ascorbate-dependent hemoperoxidase localized to the endoplasmic reticulum.

, 2002
In most aerobic organisms hemoperoxidases play a major role in H(2)O(2)-detoxification, but trypanosomatids have been reported to lack this activity.

Delineating neuroinflammation, parasite CNS invasion, and blood-brain barrier dysfunction in an experimental murine model of human African trypanosomiasis [PDF]

, 2017
Although Trypanosoma brucei spp. was first detected by Aldo Castellani in CSF samples taken from sleeping sickness patients over a century ago there is still a great deal of debate surrounding the timing, route and effects of transmigration of the ...

The return of metabolism: biochemistry and physiology of glycolysis

Biological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Measure of Molecular Diversity within the Trypanosoma brucei Subspecies Trypanosoma brucei brucei and Trypanosoma brucei gambiense as Revealed by Genotypic Characterization

Experimental Parasitology, 2001
We have evaluated whether sequence polymorphisms in the rRNA intergenic spacer region can be used to study the relatedness of two subspecies of Trypanosoma brucei. Thirteen T. brucei isolates made up of 6 T. b. brucei and 7 T. b. gambiense were analyzed using restriction fragment length polymorphism (RFLP).

Antigenic variation in the African trypanosome: molecular mechanisms and phenotypic complexity [PDF]

, 2009
Antigenic variation is an immune evasion strategy that has evolved in viral, bacterial and protistan pathogens. In the African trypanosome this involves stochastic switches in the composition of a variant surface glycoprotein (VSG) coat, using a massive ...

Equine trypanosomiasis, a systematic review and meta‐analyses: Prevalence, morbidity and mortality

Equine Veterinary Journal, EarlyView.
Abstract Background Equine trypanosomiasis is a neglected protozoal disease. Objectives To perform a systematic search of literature to explore: (1) In equines what is the global geographical distribution and prevalence of trypanosomiasis? In low and middle‐income countries (LMICs) is trypanosomiasis more prevalent than in higher‐income countries (HICs)
