Research Article | Host-Microbe BiologyMoLAEA Regulates Secondary Metabolism in Magnaporthe oryzaeM. oryzae causes blast disease, the most serious disease of cultivated rice affecting global rice production. The genome of M. oryzae has been shown to have a number of genes involved in secondary metabolism, but most of them are uncharacterized. In fact, compared to studies of other filamentous...
Research Article | Host-Microbe BiologyEnterotoxigenic Escherichia coli Heat-Stable Toxin Increases the Rate of Zinc Release from Metallothionein and Is a Zinc- and Iron-Binding PeptideEnterotoxigenic Escherichia coli (ETEC) is a major diarrheal pathogen in children in low- to middle-income countries, deployed military personnel, and travelers to regions of endemicity. The heat-stable toxin (ST) is a small nonimmunogenic secreted peptide with 3 disulfide bonds. It has been appreciated that dietary disulfides modulate intestinal redox potential and...
Research Article | Host-Microbe BiologyIdentification of the Neuroinvasive Pathogen Host Target, LamR, as an Endothelial Receptor for the Treponema pallidum Adhesin Tp0751Syphilis is a sexually transmitted infection caused by the spirochete bacterium Treponema pallidum subsp. pallidum. The continued incidence of syphilis demonstrates that screening and treatment strategies are not sufficient to curb this infectious disease, and there is currently no vaccine available. Herein we demonstrate that the...
Observation | Host-Microbe BiologyNatural Transmission of Helicobacter saguini Causes Multigenerational Inflammatory Bowel Disease in C57/129 IL-10−/− MiceWhile family history is a significant risk factor for developing inflammatory bowel disease (IBD), it is unclear whether the microbiome from parents is a transmissible influence on disease in their offspring. Furthermore, it is unknown whether IBD-associated microbes undergo genomic adaptations during multigenerational transmission and chronic colonization in their hosts. Herein, we show that a single bacterial species,...
Commentary | Host-Microbe BiologymSphere of Influence: Understanding Virus-Host Interactions Requires a Multifaceted ApproachRory de Vries works in the field of viral pathogenesis and focuses on interactions between respiratory viruses (or corresponding vaccines) and the host immune system. In this mSphere of Influence article, he reflects on how the articles “Predominant infection of CD150+ lymphocytes and dendritic cells during measles virus infection of macaques” by R. L. de Swart et al. (R. L. de Swart, M. Ludlow, L. de Witte, Y. Yanagi, et al...
Commentary | Host-Microbe BiologymSphere of Influence: Interferon Ultra Is a Means To Fight Viral DiseaseConnor G. G. Bamford works in the fields of virology and innate immunity. In this mSphere of Influence article, he reflects on how three papers by Manry et al. (J. Manry, G. Laval, E. Patin, S. Fornarino, et al., J Exp Med 208:2747–2759, 2011, https://doi.org/10.1084/jem.20111680), Terczyńska-Dyla et al. (E. Terczyńska-Dyla, S. Bibert, F. H. T. Duong, I. Krol, et al., Nat Commun 5:5699...
Perspective | Host-Microbe BiologyDoes the Evidence Support the Existence of the Simian Polyomavirus SV40 Vp4 Viroporin?The simian polyomavirus SV40 was reported to express Vp4, an N-terminally truncated form of the minor capsid proteins Vp2 and Vp3. Since a missense mutation of the putative Vp4 start codon (Vp2M228I) was found to give reduced progeny release and delayed lysis, Vp4 was claimed to be a viroporin. However, two independent research groups, including our own, were unable to replicate these findings. In contrast, we found no Vp4 expression in...
Commentary | Host-Microbe BiologymSphere of Influence: Predicting Immune Responses and Susceptibility to Influenza Virus—May the Data Be with YouIrene Ramos works in the field of immunology to viral infections. In this mSphere of Influence article, she reflects on how “Global analyses of human immune variation reveal baseline predictors of postvaccination responses” by Tsang et al. (Cell 157:499–513, 2014, https://doi.org/10.1016/j.cell.2014.03.031) and “A crowdsourced analysis to identify ab initio molecular signatures...
Editor's Pick Commentary | Host-Microbe BiologyCOVID-19: Knowns, Unknowns, and QuestionsThe recent emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from the Hubei province in China in late 2019 demonstrates the epidemic potential of coronaviruses. The rapid spread of this virus across the world in only 2 months highlights the transmissibility of this family of viruses and the significant morbidity and mortality that they can cause. We highlight the current state of knowledge of coronavirus biology...
Editor's Pick Research Article | Host-Microbe BiologyType III Secretion Effector VopQ of Vibrio parahaemolyticus Modulates Central Carbon Metabolism in Epithelial CellsThe metabolic response of host cells upon infection is pathogen specific, and infection-induced host metabolic reprogramming may have beneficial effects on the proliferation of pathogens. V. parahaemolyticus contains a range of virulence factors to manipulate host signaling pathways and metabolic processes. In this study, we identified that the T3SS1 VopQ effector...
