    Trends Parasitol. (IF 8.02) Pub Date : 2020-04-06
    Borko Amulic; Christopher A. Moxon; Aubrey J. Cunnington

    Neutrophils are abundant innate immune cells with crucial roles in immunity and vascular inflammation. Recent evidence indicates that neutrophils have a dual role in malaria, contributing to both pathogenesis and control of Plasmodium. We discuss emerging mechanisms behind these opposing functions and identify key outstanding questions.

    Estimation of Plasmodium vivax biomass based on circulating biomarkers indicates the existence of a predominant biomass outside of the circulation that is not captured by peripheral parasitemia, in particular in patients with complicated outcomes. A series of recent studies have suggested that the hematopoietic niche of the bone marrow (BM) is a major reservoir for parasite replication and the development

  • The Human Spleen in Malaria: Filter or Shelter?
    Trends Parasitol. (IF 8.02) Pub Date : 2020-03-30
    Benoît Henry; Camille Roussel; Mario Carucci; Valentine Brousse; Papa Alioune Ndour; Pierre Buffet

    The human spleen is an immune sentinel and controls red blood cell (RBC) quality. By mechanically retaining subsets of infected RBCs, the spleen may reduce the pace at which the parasite biomass increases before the adaptive immune response operates. Conversely, the spleen may contribute to malaria pathogenesis, particularly anemia that is associated with splenomegaly. Large spleens may also shelter

  • Inflammasome Activation in Response to Intracellular Protozoan Parasites
    Trends Parasitol. (IF 8.02) Pub Date : 2020-03-23
    Renan V.H. de Carvalho; Dario S. Zamboni

    Inflammasomes are cytosolic complexes that assemble in response to cellular stress or upon sensing microbial molecules, culminating in cytokine processing and an inflammatory form of cell death called pyroptosis. Inflammasomes are usually composed of a sensor molecule, an adaptor protein, and an inflammatory caspase, such as Caspase-1, which cleaves and activates multiple substrates, including Gasdermin-D

  • Malaria Parasite Clearance: What Are We Really Measuring?
    Trends Parasitol. (IF 8.02) Pub Date : 2020-03-21
    David S. Khoury; Sophie G. Zaloumis; Matthew J. Grigg; Ashraful Haque; Miles P. Davenport

    Antimalarial drugs are vital for treating malaria and controlling transmission. Measuring drug efficacy in the field requires large clinical trials and thus we have identified proxy measures of drug efficacy such as the parasite clearance curve. This is often assumed to measure the rate of drug activity against parasites and is used to predict optimal treatment regimens required to completely clear

  • Reinventing the Wheel of Echinococcus granulosus sensu lato Transmission to Humans
    Trends Parasitol. (IF 8.02) Pub Date : 2020-03-21
    Francesca Tamarozzi; Peter Deplazes; Adriano Casulli

    Control of cystic echinococcosis (CE) relies on interrupting Echinococcus granulosus sensu lato transmission through interventions in dogs and livestock. However, primary prevention measures aimed at avoiding ingestion of Echinococcus eggs may help reduce the burden of human CE. CE is generally considered, to variable extents, to be foodborne, but there is little evidence on the actual contamination

  • Not Just from Blood: Mosquito Nutrient Acquisition from Nectar Sources
    Trends Parasitol. (IF 8.02) Pub Date : 2020-03-17
    Elina Barredo; Matthew DeGennaro

    Anthropophilic female mosquitoes are well known for their strong attraction to human hosts, but plant nectar is a common energy source in their diets. When sugar sources are scarce, female mosquitoes of some species can compensate by taking larger and more frequent blood meals. Male mosquitoes are exclusively dependent on plant nectar or alternative sugar sources. Plant preference is likely driven

  • An Omnivore’s Dilemma: Toxoplasma gondii’s Flexible Metabolic Networks
    Trends Parasitol. (IF 8.02) Pub Date : 2020-03-08
    Kami Kim

    Host cells provide protection from the environment for intracellular pathogens, but acquisition of nutrients and sensing of changes in the host cell bring new challenges. Krishnan et al. have recently developed a comprehensive genome-scale metabolic model (GEM) of the Toxoplasma gondii metabolic network that incorporates genetic, transcriptomic, and metabolomic data.

    Trends Parasitol. (IF 8.02) Pub Date : 2020-03-04
    Karthikeyan Chandrasegaran; Chloé Lahondère; Luis E. Escobar; Clément Vinauger

    Mosquitoes are considered to be the deadliest animals on Earth because the diseases they transmit claim at least a million human lives every year globally. Here, we discuss the scales at which the effects of ecological factors cascade to influence epidemiologically relevant behaviors of adult mosquitoes. In particular, we focused our review on the environmental conditions (coarse-scale variables) that

  • Chimeras of P4-ATPase and Guanylate Cyclase in Pathogenic Protists
    Trends Parasitol. (IF 8.02) Pub Date : 2020-03-04
    Özlem Günay-Esiyok; Nishith Gupta

    Apicomplexan parasites harbor chimeric proteins embodying P4-type ATPase and guanylate cyclase domains. Such proteins – serving as the actuator of cGMP signaling in this group of important pathogens – are indeed unusual in terms of their sheer size, modus operandi, and evolutionary repurposing. Much like the mythological Sphinx, a human-lion chimeric creature that posed challenging riddles, the P4-type

McDermott; Torsten Ochsenreiter; Laurie K. Read; Reza Salavati; Achim Schnaufer; André Schneider; Larry Simpson; Kenneth Stuart; Ruslan Aphasizhev

    Trypanosoma brucei spp. cause African human and animal trypanosomiasis, a burden on health and economy in Africa. These hemoflagellates are distinguished by a kinetoplast nucleoid containing mitochondrial DNAs of two kinds: maxicircles encoding ribosomal RNAs (rRNAs) and proteins and minicircles bearing guide RNAs (gRNAs) for mRNA editing. All RNAs are produced by a phage-type RNA polymerase as 3′

  • Trypanosoma cruzi Calreticulin: Immune Evasion, Infectivity, and Tumorigenesis
    Trends Parasitol. (IF 8.02) Pub Date : 2020-02-24
    Galia Ramírez-Toloza; Eduardo Sosoniuk-Roche; Carolina Valck; Lorena Aguilar-Guzmán; Viviana P. Ferreira; Arturo Ferreira

    To successfully infect, Trypanosoma cruzi evades and modulates the host immune response. T. cruzi calreticulin (TcCalr) is a multifunctional, endoplasmic reticulum (ER)-resident chaperone that, translocated to the external microenvironment, mediates crucial host–parasite interactions. TcCalr binds and inactivates C1 and mannose-binding lectin (MBL)/ficolins, important pattern- recognition receptors

  • Transition from Plasmodial Hypnozoite to Schizont Demonstrated
    Trends Parasitol. (IF 8.02) Pub Date : 2020-02-19
    Miles B. Markus

    The progression to schizont formation of individual activated hypnozoites has been observed in vitro for the first time by Voorberg-van der Wel et al. Green-fluorescent protein-positive hypnozoites turned red-fluorescent (mCherry) upon activation. Thus, we now have empirical parasitological proof that supports the 40-year-old hypnozoite theory of relapse in malaria.

    Trends Parasitol. (IF 8.02) Pub Date : 2020-02-19
    Swati Dass; Michael W. Mather; Hangjun Ke

    The mitochondrion in parasitic protozoans is a clinically proven drug target. A specialized ribosome (mitoribosome) is required to translate genes encoded on the mitochondrial (mt) DNA. Despite the significance, little is known about mitoribosomes in many medically and economically important unicellular protozoans.

  • Next-Generation Molecular Surveillance of TriTryp Diseases
    Trends Parasitol. (IF 8.02) Pub Date : 2020-02-17
    Malgorzata Anna Domagalska; Jean-Claude Dujardin

    Elimination programs targeting TriTryp diseases (Leishmaniasis, Chagas' disease, human African trypanosomiasis) significantly reduced the number of cases. Continued surveillance is crucial to sustain this progress, but parasite molecular surveillance by genotyping is currently lacking. We explain here which epidemiological questions of public health and clinical relevance could be answered by means

    Trends Parasitol. (IF 8.02) Pub Date : 2020-02-08
    Jianchun Xiao

    A key strategy that many parasites use to facilitate transmission involves behavioral modification of their hosts. Toxoplasma gondii has been taken as an example for this strategy. A recent study by Boillat et al. reported that attraction to predator odor following Toxoplasma infection is not specific to felines.

    Trends Parasitol. (IF 8.02) Pub Date : 2020-02-06
    Danielle L Cantrell,Maya L Groner,Tal Ben-Horin,Jon Grant,Crawford W Revie

    In marine ecosystems, oceanographic processes often govern host contacts with infectious agents. Consequently, many approaches developed to quantify pathogen dispersal in terrestrial ecosystems have limited use in the marine context. Recent applications in marine disease modeling demonstrate that physical oceanographic models coupled with biological models of infectious agents can characterize dispersal

    Trends Parasitol. (IF 8.02) Pub Date : 2020-01-31
    Balázs Szöőr,Eleanor Silvester,Keith R Matthews

    African trypanosomes are mainly transmitted by tsetse flies. In recent years there has been good progress in understanding how the parasites prepare for transmission, detect their changed environment through the perception of different environmental cues, and respond by changing their developmental gene expression. In this review, we discuss the different signals and signaling mechanisms used by the

  • Skin Interface, a Key Player for Borrelia Multiplication and Persistence in Lyme Borreliosis.
    Trends Parasitol. (IF 8.02) Pub Date : 2020-01-29
    Quentin Bernard,Antoine Grillon,Cédric Lenormand,Laurence Ehret-Sabatier,Nathalie Boulanger

    The skin plays a key role in vector-borne diseases because it is the site where the arthropod coinoculates pathogens and its saliva. Lyme borreliosis, particularly well investigated in this context, is a multisystemic infectious disease caused by Borrelia burgdorferi sensu lato and transmitted by the hard tick Ixodes. Numerous in vitro studies were conducted to better understand the role of specific

    Trends Parasitol. (IF 8.02) Pub Date : 2019-12-19
    Daniel E Goldberg,Joshua Zimmerberg

    When a malaria parasite invades a host erythrocyte it pushes itself in and invaginates a portion of the host membrane, thereby sealing itself inside and establishing itself in the resulting vacuole. The parasitophorous vacuolar membrane (PVM) that surrounds the parasite is modified by the parasite, using its secretory organelles. To survive within this enveloping membrane, the organism must take in

    Grazing mammals, ungulates, pose two evolutionary puzzles as helminth hosts. First, why do some helminths infect intermediate hosts prior to infecting ungulates, given that grazers could directly consume propagules on vegetation? Second, ungulates are large and long-lived, so why are they occasionally intermediate instead of definitive hosts, as in taeniid cestodes? We comprehensively surveyed helminth
