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 ...

Leishmania donovani's protein tyrosine phosphatases interact with DUF21 and respond to environmental magnesium

The FEBS Journal, EarlyView.
The Leishmania phosphatase PTP1, and possibly the genetically similar PTP2, interacts with the Leishmania transmembrane protein DUF21. When both ptp1 and ptp2 are knocked out of Leishmania (LdΔPTP1/2), the parasite can no longer survive without magnesium in vitro and has reduced viability in the host macrophage. Conversely, in duf21 knockout (LdΔDUF21),

TbTim20 facilitates protein import at a low membrane potential in trypanosomes lacking the mitochondrial genome

The FEBS Journal, EarlyView.
Protein import into mitochondria relies on TIM complexes and the membrane potential. Trypanosoma brucei has a unique TIM complex, and the role of one subunit, TbTim20, has remained unclear. Here, we show that TbTim20 is essential in cells lacking mitochondrial DNA. The importance of TbTim20 increases as the membrane potential decreases.

The structural, functional, and therapeutic potential of metacaspases in fungi and protozoa

The FEBS Journal, EarlyView.
Metacaspases are Ca2+‐dependent cysteine proteases whose structural characteristics, particularly calcium binding and autocatalytic processing, govern their activation and biological functions. These enzymes differ among microorganisms and regulate their cell cycles, making them excellent targets for drug development.

Preassembled complexes of hAgo2 and ssRNA delivered by nanoparticles: a novel silencing gene expression approach overcoming the absence of the canonical pathway of siRNA processing in the apicomplexan parasite Babesia microti, blood parasite of veterinary and zoonotic importance

Emerging Microbes and Infections
Due to the lack of efficacy of the currently used chemical drugs, poor tick control, and lack of effective vaccines against Babesia, novel control strategies are urgently needed.

Crystalizing the genetic code

, 2000
New developments are presented in the framework of the model introduced by the authors in refs. [1,2] and in which nucleotides as well as codons are classified in crystal bases of the quantum group U_q(sl(2)+sl(2)) in the limit q -> 0.

Screening for Trypanosoma cruzi infection (Chagas disease) in the Latin American population living with HIV in London

HIV Medicine, EarlyView.
Abstract Background There are an estimated 2482 people born in Latin American countries receiving care for HIV in the United Kingdom. Although national guidance recommends screening for Trypanosoma cruzi infection (Chagas disease) in this population, there is no formal screening programme.

Blastocystis Sp: a Neglected Zoonotic Protozoan [PDF]

The significance of Blastocystis as a cause of human and animal disease remains unknown. It has been suggested that the organism is zoonotic. This study was undertaken to determine the prevalence of Blastocystis sp in stray dogs, which may be ...
