A host transcriptional signature for presymptomatic detection of infection in humans exposed to influenza H1N1 or H3N2.
(PLoS One, 2013)There is great potential for host-based gene expression analysis to impact the early diagnosis of infectious diseases. In particular, the influenza pandemic of 2009 highlighted the challenges and limitations of traditional ... -
BPIFB3 regulates autophagy and coxsackievirus B replication through a noncanonical pathway independent of the core initiation machinery.
(mBio, 2014-12-09)<h4>Unlabelled</h4>Enteroviruses require autophagy to facilitate the formation of autophagosome (AP)-like double-membrane vesicles that provide the scaffolding for RNA replication. Here, we identify bactericidal/permeabi... -
Dual impact of elevated temperature on plant defence and bacterial virulence in Arabidopsis.
(Nature communications, 2017-11-27)Environmental conditions profoundly affect plant disease development; however, the underlying molecular bases are not well understood. Here we show that elevated temperature significantly increases the susceptibility of ... -
Elucidation of hepatitis C virus transmission and early diversification by single genome sequencing.
(PLoS Pathog, 2012)A precise molecular identification of transmitted hepatitis C virus (HCV) genomes could illuminate key aspects of transmission biology, immunopathogenesis and natural history. We used single genome sequencing of 2,922 half ... -
Enteroviruses: A Gut-Wrenching Game of Entry, Detection, and Evasion.
(Viruses, 2019-05-21)Enteroviruses are a major source of human disease, particularly in neonates and young children where infections can range from acute, self-limited febrile illness to meningitis, endocarditis, hepatitis, and acute flaccid ... -
Gene expression-based classifiers identify Staphylococcus aureus infection in mice and humans.
(PLoS One, 2013)Staphylococcus aureus causes a spectrum of human infection. Diagnostic delays and uncertainty lead to treatment delays and inappropriate antibiotic use. A growing literature suggests the host's inflammatory response to the ... -
Host gene expression classifiers diagnose acute respiratory illness etiology.
(Sci Transl Med, 2016-01-20)Acute respiratory infections caused by bacterial or viral pathogens are among the most common reasons for seeking medical care. Despite improvements in pathogen-based diagnostics, most patients receive inappropriate antibiotics. ... -
Host genetics and HIV-1: the final phase?
(PLoS Pathog, 2010-10-14)This is a crucial transition time for human genetics in general, and for HIV host genetics in particular. After years of equivocal results from candidate gene analyses, several genome-wide association studies have been published ... -
Imaging-Based Reporter Systems to Define CVB-Induced Membrane Remodeling in Living Cells.
(Viruses, 2020-09-25)Enteroviruses manipulate host membranes to form replication organelles, which concentrate viral and host factors to allow for efficient replication. However, this process has not been well-studied in living cells throughout ... -
Minimal within-host dengue models highlight the specific roles of the immune response in primary and secondary dengue infections.
(J R Soc Interface, 2015-02-06)In recent years, the within-host viral dynamics of dengue infections have been increasingly characterized, and the relationship between aspects of these dynamics and the manifestation of severe disease has been increasingly ... -
Search for microRNAs expressed by intracellular bacterial pathogens in infected mammalian cells.
(PLoS One, 2014)MicroRNAs are expressed by all multicellular organisms and play a critical role as post-transcriptional regulators of gene expression. Moreover, different microRNA species are known to influence the progression of a range ... -
Shared monocyte subset phenotypes in HIV-1 infection and in uninfected subjects with acute coronary syndrome.
(Blood, 2012-11-29)The mechanisms responsible for increased cardiovascular risk associated with HIV-1 infection are incompletely defined. Using flow cytometry, in the present study, we examined activation phenotypes of monocyte subpopulations ... -
Stem Cell-Derived Models of Viral Infections in the Gastrointestinal Tract.
(Viruses, 2018-03-10)Studies on the intestinal epithelial response to viral infection have previously been limited by the absence of in vitro human intestinal models that recapitulate the multicellular complexity of the gastrointestinal tract. ... -
Systematic comparison of published host gene expression signatures for bacterial/viral discrimination.
(Genome medicine, 2022-02-21)<h4>Background</h4>Measuring host gene expression is a promising diagnostic strategy to discriminate bacterial and viral infections. Multiple signatures of varying size, complexity, and target populations have been described. ... -
Temporal dynamics of host molecular responses differentiate symptomatic and asymptomatic influenza a infection.
(PLoS Genet, 2011-08)Exposure to influenza viruses is necessary, but not sufficient, for healthy human hosts to develop symptomatic illness. The host response is an important determinant of disease progression. In order to delineate host molecular ... -
The host transcriptional response to Candidemia is dominated by neutrophil activation and heme biosynthesis and supports novel diagnostic approaches.
(Genome medicine, 2021-07)<h4>Background</h4>Candidemia is one of the most common nosocomial bloodstream infections in the United States, causing significant morbidity and mortality in hospitalized patients, but the breadth of the host response to ... -
The Impact of Surfactant Protein D, Interleukin‑5, and Eosinophilia on Cryptococcosis
(2013)<italic>Cryptococcus neoformans</italic> is an opportunistic fungal pathogen that initiates infection following inhalation. As a result, the pulmonary immune response provides a first line of defense against <italic>C. ... -
The Macrophage-Specific Promoter mfap4 Allows Live, Long-Term Analysis of Macrophage Behavior during Mycobacterial Infection in Zebrafish.
(PLoS One, 2015)Transgenic labeling of innate immune cell lineages within the larval zebrafish allows for real-time, in vivo analyses of microbial pathogenesis within a vertebrate host. To date, labeling of zebrafish macrophages has been ... -
The Role of Erythrocytic miRNA in the lifecycle of Plasmodium falciparum
(2012)Malaria, caused by the apicomplexan parasite Plasmodium, is a disease which affects up to 500 million people each year. Historically, malaria infection has been combated both through the control of its vector, the Anopheles ... -
Transcriptomic Analysis of the Host Response and Innate Resilience to Enterotoxigenic Escherichia coli Infection in Humans.
(J Infect Dis, 2016-05-01)BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is a globally prevalent cause of diarrhea. Though usually self-limited, it can be severe and debilitating. Little is known about the host transcriptional response to infection. ...
