(De)glutamylation and cell death in Leishmania parasites.

PLoS Negl Trop Dis 2019 Apr 24;13(4):e0007264. Epub 2019 Apr 24.

Aix Marseille Univ, IRD, AP-HM, SSA, VITROME, Marseille, France.

Trypanosomatids are flagellated protozoan parasites that are very unusual in terms of cytoskeleton organization but also in terms of cell death. Most of the Trypanosomatid cytoskeleton consists of microtubules, forming different substructures including a subpellicular corset. Oddly, the actin network appears structurally and functionally different from other eukaryotic actins. Read More

Side chain rotameric changes and backbone dynamics enable specific cladosporin binding in Plasmodium falciparum lysyl-tRNA synthetase.

Proteins 2019 Apr 24. Epub 2019 Apr 24.

Structural Parasitology, Molecular Medicine Group, International Center for Genetic Engineering and Biotechnology, New Delhi, India.

Cladosporin (CLD) is a fungal metabolite that kills malaria parasite via inhibiting its cytoplasmic lysyl-tRNA synthetase (KRS) and abrogating protein translation. Here we provide structural and drug selectivity analyses on CLD interacting residues in apo and holo KRSs from Plasmodium falciparum, Homo sapiens, Cryptosporidium parvum and Mycobacterium ulcerans. We show that both gross and subtle alterations in protein backbone and sidechains drive the active site structural plasticity that allows integration of CLD in KRSs. Read More

As the largest and most complex ecosystem in humans, gut microbiota resides in human or animal gastrointestinal tract with intestinal viruses and parasites. Previous studies have demonstrated that gut microbiotadysbiosis is strongly correlated with the development, progression and prognosis of multiple diseases. The parasites that are colonized in the host, may directly or indirectly affect gut microbiota and the gut microbiota-host homeostasis, and changes in the composition and diversity of gut microbiota may also affect parasitic infections and the development, progression and prognosis of parasitic diseases.

Zhongguo Xue Xi Chong Bing Fang Zhi Za Zhi 2019 Apr;31(1):40-46

Shanghai Veterinary Research Institute, Chinese Academy of Agricultural Sciences; Key Laboratory of Animal Parasitology, Minis-try of Agriculture; National Reference Laboratory of Animal Schistosomiasis, Shanghai 200241, China.

This paper describes the damages caused by animal schistosomiasis and the role of animals in the transmission of schistosomiasis in China and reviews the progress of animal schistosomiasis control and the endemic status of animal schistosomiasis at various stages. Although the endemic situation of animal schistosomiasis has been effectively controlled, there are still multiple factors that affect the transmission of schistosomiasis, and there are still risks leading to reemergence or rebounding of schistosomiasis in local areas. Strengthening of schistosomiasis surveillance as well as the prevention and control effects in key areas, consolidation of schistosomiasis control achievements, resolving of key technical problems in the elimination of animal schistosomiasis and development of precise technical measures and strategies are needed to accelerate the progress towards the elimination of schistosomiasis in China.

The role of polyamines in the regulation of macrophage polarization and function.

Amino Acids 2019 Apr 23. Epub 2019 Apr 23.

Division of Gastroenterology, Hepatology and Nutrition, Department of Medicine, Vanderbilt University Medical Center, Vanderbilt University School of Medicine, 2215 Garland Avenue, Room 1030C Medical Research Building IV, Nashville, TN, 37232, USA.

Naturally occurring polyamines are ubiquitously distributed and play important roles in cell development, amino acid and protein synthesis, oxidative DNA damage, proliferation, and cellular differentiation. Macrophages are essential in the innate immune response, and contribute to tissue remodeling. Naïve macrophages have two major potential fates: polarization to (1) the classical pro-inflammatory M1 defense response to bacterial pathogens and tumor cells, and (2) the alternatively activated M2 response, induced in the presence of parasites and wounding, and also implicated in the development of tumor-associated macrophages.

The Impact of Anthelmintic Treatment on Human Gut Microbiota Based on Cross-Sectional and Pre- and Postdeworming Comparisons in Western Kenya.

MBio 2019 Apr 23;10(2). Epub 2019 Apr 23.

Helminth Immunology Section, Laboratory of Parasitic Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, Maryland, USA.

Murine studies suggest that the presence of some species of intestinal helminths is associated with changes in host microbiota composition and diversity. However, studies in humans have produced varied conclusions, and the impact appears to vary widely depending on the helminth species present. To demonstrate how molecular approaches to the human gut microbiome can provide insights into the complex interplay among disparate organisms, DNA was extracted from cryopreserved stools collected from residents of 5 rural Kenyan villages prior to and 3 weeks and 3 months following albendazole (ALB) therapy.

Immunity of leaf-cutting ants and its role in host-parasitoid relationships.

J Insect Physiol 2019 Apr 20. Epub 2019 Apr 20.

School of Life Sciences, University of Sussex, Brighton, BN1 9QG, United Kingdom.

Parasites are an important selection pressure for all organisms, and host immune responses are key in shaping host-parasite interactions. Host species with strong immune defences may be expected to experience lower parasitism; on the other hand, investment in immune function is costly, so hosts that have evolved to invest more in immune defence may be expected to have been under greater selection pressure from parasites. Disentangling the coevolutionary dynamics requires comparative studies that quantify the immune responses of potential hosts of parasites in a community, but such studies are rare. Read More

Prevalence and zoonotic potential of intestinal protozoans in bovines in Northern India.

Vet Parasitol Reg Stud Reports 2018 Aug 12;13:92-97. Epub 2018 Apr 12.

Parasitology Lab, Department for Food Safety and Infection Biology, Faculty of Veterinary Medicine, Norwegian University of Life Sciences, Adamstuen Campus, PO Box 8146 Dep., 0033 Oslo, Norway.

Bovines, and especially cattle, have a dual position of appreciation in India, being both important in the food industry as providers of dairy products, and, culturally, being considered as holy creatures that must not be harmed, killed or eaten. This status means that cattle have a paradoxical existence in India; as they are worshipped and protected, they are able to roam freely among humans, but they are also often left to fend for themselves. The water buffalo represents a significant contributor to the Indian agricultural economy as well as general social development, and are in this way somehow replacing the indigenous cattle.
