Global Health Faculty Publications

BACKGROUND: Adverse birth outcomes, including low birth weight (LBW), defined as <2500 >grams, small-for-gestational-age (SGA), and prematurity, contribute to 60%-80% of infant mortality worldwide and may be related to infections during pregnancy. The aim of this study was to assess whether febrile human rhinovirus (HRV) illness is associated with adverse birth outcomes.

METHODS: Active household-based weekly surveillance was performed for respiratory illness episodes in pregnant women as part of a community-based, prospective, randomized trial of maternal influenza immunization in rural Nepal. Rhinovirus (HRV) febrile illness episodes were defined as fever plus cough, sore throat, runny nose, and/or myalgia with HRV detected …

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Food borne trematodes (FBTs) are an assemblage of platyhelminth parasites transmitted through the food chain, four of which are recognized as neglected tropical diseases (NTDs). Fascioliasis stands out among the other NTDs due to its broad and significant impact on both human and animal health, as Fasciola sp., are also considered major pathogens of domesticated ruminants. Here we present a reference genome sequence of the common liver fluke, Fasciola hepatica isolated from sheep, complementing previously reported isolate from cattle. A total of 14,642 genes were predicted from the 1.14 GB genome of the liver fluke. Comparative genomics indicated that F. …

The Herpevac Trial For Women: Sequence Analysis Of Glycoproteins From Viruses Obtained From Infected Subjects., Miguel A Minaya, Maria Korom, Hong Wang, Robert B Belshe, Lynda A Morrison

Microbiology, Immunology, and Tropical Medicine Faculty Publications

The Herpevac Trial for Women revealed that three dose HSV-2 gD vaccine was 58% protective against culture-positive HSV-1 genital disease, but it was not protective against HSV-2 infection or disease. To determine whether vaccine-induced immune responses had selected for a particular gD sequence in strains infecting vaccine recipients compared with viruses infecting control subjects, genetic sequencing studies were carried out on viruses isolated from subjects infected with HSV-1 or HSV-2. We identified naturally occurring variants among the gD sequences obtained from 83 infected subjects. Unique or low frequency amino acid substitutions in the ectodomain of gD were found in 6 …

Enriched Environment And Stress Exposure Influence Splenic B Lymphocyte Composition., Blake T Gurfein, Burcu Hasdemir, Jeffrey M Milush, Chadi Touma, Rupert Palme, Douglas F Nixon, Nicholas Darcel, Frederick M Hecht, Aditi Bhargava

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Prolonged chronic stress has deleterious effects on immune function and is associated with numerous negative health outcomes. The spleen harbors one-fourth of the body’s lymphocytes and mediates both innate and adaptive immune responses. However, the subset of splenic lymphocytes that respond, either adaptively or maladaptively, to various stressors remains largely unknown. Here we investigated the effects of unpredictable chronic mild stress (CMS) exposure on spleen composition in male mice housed in two different caging conditions: standard caging (Cntl) and enriched environment (EE). EE-caged mice exhibited the greatest absolute number of splenocytes and CMS exposure significantly lowered splenocyte numbers in both …

A Modified Fasp Protocol For High-Throughput Preparation Of Protein Samples For Mass Spectrometry., Jeremy Potriquet, Marut Laohaviroj, Jeffrey M Bethony, Jason Mulvenna

Microbiology, Immunology, and Tropical Medicine Faculty Publications

o facilitate high-throughput proteomic analyses we have developed a modified FASP protocol which improves the rate at which protein samples can be processed prior to mass spectrometry. Adapting the original FASP protocol to a 96-well format necessitates extended spin times for buffer exchange due to the low centrifugation speeds tolerated by these devices. However, by using 96-well plates with a more robust polyethersulfone molecular weight cutoff membrane, instead of the cellulose membranes typically used in these devices, we could use isopropanol as a wetting agent, decreasing spin times required for buffer exchange from an hour to 30 minutes. In a …

Schistosoma Mansoni Reinfection: Analysis Of Risk Factors By Classification And Regression Tree (Cart) Modeling., Andréa Gazzinelli, Roberta Oliveira-Prado, Leonardo Ferreira Matoso, Bráulio M Veloso, Gisele Andrade, Helmut Kloos, Jeffrey M Bethony, Renato M Assunção, Rodrigo Correa-Oliveira

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Praziquantel (PZQ) is an effective chemotherapy for schistosomiasis mansoni and a mainstay for its control and potential elimination. However, it does not prevent against reinfection, which can occur rapidly in areas with active transmission. A guide to ranking the risk factors for Schistosoma mansoni reinfection would greatly contribute to prioritizing resources and focusing prevention and control measures to prevent rapid reinfection. The objective of the current study was to explore the relationship among the socioeconomic, demographic, and epidemiological factors that can influence reinfection by S. mansoni one year after successful treatment with PZQ in school-aged children in Northeastern Minas …

Mycobacterium Tuberculosis Reactivates Latent Hiv-1 In T Cells In Vitro, Erica Larson, Camille Novis, Laura Martins, Amanda Macedo, Kadyn Kimball, Alberto Bosque, Vincent Planelles, Louis Barrows

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Following proviral integration into the host cell genome and establishment of a latent state, the human immunodeficiency virus type 1 (HIV-1) can reenter a productive life cycle in response to various stimuli. HIV-1 reactivation occurs when transcription factors, such as nuclear factor-κB (NF-κB), nuclear factor of activated T cells (NFAT), and activator protein -1 (AP-1), bind cognate sites within the long terminal repeat (LTR) region of the HIV-1 provirus to promote transcription. Interestingly, pattern recognition receptors (PRRs) that recognize pathogen-associated molecular patterns (PAMPs) can reactivate latent HIV-1 through activation of the transcription factor NF-κB. Some PRRs are expressed on central …

Downregulated Il-21 Response And T Follicular Helper Cell Exhaustion Correlate With Compromised Cd8 T Cell Immunity During Chronic Toxoplasmosis, Magali M. Moretto, Sujin Hwang, Imtiaz A. Khan

Microbiology, Immunology, and Tropical Medicine Faculty Publications

CD8 T cells are important for maintaining the chronicity of Toxoplasma gondii infection. In a T. gondii encephalitis susceptible model, we recently demonstrated that CD4 T cells play an essential helper role in the maintenance of the effector response and CD8 T cell dysfunctionality was linked to CD4 T cell exhaustion. However, CD4 T cells are constituted of different subsets with various functions and the population(s) providing help to the CD8 T cells has not yet been determined. In the present study, Tfh cells (T follicular helper), which are known to be essential for B cell maturation and are one …

Ancylostoma Ceylanicum Infective Third-Stage Larvae Are Activated By Co-Culture With Ht-29-Mtx Intestinal Epithelial Cells, Caitlin Feather, John M. Hawdon, John March

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background

Human hookworm larvae arrest development until they enter an appropriate host. This makes it difficult to access the larvae for studying larval development or host-parasite interactions. While there are in vivo and in vitro animal models of human hookworm infection, there is currently no human, in vitro model. While animal models have provided much insight into hookworm biology, there are limitations to how closely this can replicate human infection. Therefore, we have developed a human, in vitro model of the initial phase of hookworm infection using intestinal epithelial cell culture.

Results

Co-culture of the human hookworm Ancylostoma ceylanicum with …

Pediatric Cardiovascular Care In Uganda: Current Status, Challenges, And Opportunities For The Future., Twalib Olega Aliku, Sulaiman Lubega, Judith Namuyonga, Tom Mwambu, Michael Oketcho, John O Omagino, Craig Sable, Peter Lwabi

Pediatrics Faculty Publications

In many developing countries, concerted action against common childhood infectious diseases has resulted in remarkable reduction in infant and under-five mortality. As a result, pediatric cardiovascular diseases are emerging as a major contributor to childhood morbidity and mortality. Pediatric cardiac surgery and cardiac catheterization interventions are available in only a few of Sub-Saharan African countries. In Uganda, open heart surgeries (OHSs) and interventional procedures for pediatric cardiovascular disease are only possible at the Uganda Heart Institute (UHI), having been started with the help of expatriate teams from the years 2007 and 2012, respectively. Thereafter, independent OHS and cardiac catheterization have …

African Americans have higher rates of asthma prevalence, morbidity, and mortality in comparison with other racial groups. We sought to characterize endotypes of childhood asthma severity in African American patients in an inner-city pediatric asthma population. Baseline blood neutrophils, blood eosinophils, and 38 serum cytokine levels were measured in a sample of 235 asthmatic children (6-17 years) enrolled in the NIAID (National Institute of Allergy and Infectious Diseases)-sponsored Asthma Phenotypes in the Inner City (APIC) study (ICAC (Inner City Asthma Consortium)-19). Cytokines were quantified using a MILLIPLEX panel and analyzed on a Luminex analyzer. Patients were classified as Easy-to-Control or …

Plasmodium Falciparum Histidine-Rich Protein-2 Plasma Concentrations Are Higher In Retinopathy-Negative Cerebral Malaria Than In Severe Malarial Anemia., Gregory S Park, Robert O Opoka, Estela Shabani, Alexis Wypyszynski, Benjamin Hanisch, Chandy C John

Pediatrics Faculty Publications

Background

Malaria retinopathy has been proposed as marker of “true” cerebral malaria (CM), ie, coma due to Plasmodium falciparum vs coma due to other causes, with incidental P falciparum parasitemia. Plasma P falciparum histidine-rich protein-2 (PfHRP2) concentrations distinguish retinopathy-positive (RP) from retinopathy-negative (RN) CM but have not been compared between RN CM and other forms of severe malaria or asymptomatic parasitemia (AP). Methods

We compared plasma PfHRP2 concentrations in 260 children with CM (247 examined for retinopathy), 228 children with severe malarial anemia (SMA), and 30 community children with AP. Results

Plasmodium falciparum HRP2 concentrations were higher in children with …

H-Ipse Is A Pathogen-Secreted Host Nucleus Infiltrating Protein (Infiltrin) 3 Expressed Exclusively By The Schistosoma Haematobium Egg Stage, Luke Pennington, Abdulaziz Alouffi, Evaristus Mbanefo, Debalina Ray, David Heery, Theodore Jardetzky, Michael Hsieh, Franco Falcone

Urology Faculty Publications

Urogenital schistosomiasis, caused by the parasitic trematode Schistosoma haematobium, affects over 112 million people worldwide. As with S. mansoniinfections, the pathology in urogenital schistosomiasis is mainly related to the egg stage, which induces granulomatous inflammation of affected tissues. Schistosoma eggs and their secretions have been studied extensively for the related S. mansoniorganism which is more amenable to laboratory studies. Indeed, we have shown that IPSE/alpha-1 (M-IPSE herein), a major protein secreted from S .mansoni eggs, can infiltrate host cells. Although M-IPSE function is unknown, its ability to translocate to their nucleus and bind DNA suggests a possible …

Prevention and Community Health Faculty Publications

Background: Little is known about the clinical care experiences of HIV-infected persons in St. Petersburg who have experience with incarceration. To address this question, we conducted a capture-recapture study to identify individuals who had been diagnosed with HIV infection while incarcerated and who subsequently presented for medical care in St. Petersburg, Russia following release from prison.

Methods: We matched 292 HIV-positive prisoners tested by the prison system in 2010 to the medical records at the St. Petersburg AIDS Center in the following 4 years.

Results: The data analysis shows that as many as half of HIV+ prisoners fail to seek …

The Temporal Dynamics Of The Tracheal Microbiome In Tracheostomised Patients With And Without Lower Respiratory Infections., Marcos Pérez-Losada, Robert J Graham, Madeline Coquillette, Amenah Jafarey, Eduardo Castro-Nallar, Manuel Aira, Robert J Freishtat, Jonathan M Mansbach

Computational Biology Institute

Background: Airway microbiota dynamics during lower respiratory infection (LRI) are still poorly understood due, in part, to insufficient longitudinal studies and lack of uncontaminated lower airways samples. Furthermore, the similarity between upper and lower airway microbiomes is still under debate. Here we compare the diversity and temporal dynamics of microbiotas directly sampled from the trachea via tracheostomy in patients with (YLRI) and without (NLRI) lower respiratory infections. Methods: We prospectively collected 127 tracheal aspirates across four consecutive meteorological seasons (quarters) from 40 patients, of whom 20 developed LRIs and 20 remained healthy. All aspirates were collected when patients had no …

Pathology Faculty Publications

Hepatitis C virus infection induces inflammation and while it is believed that HIV co-infection enhances this response, HIV control may reduce inflammation and liver fibrosis in resolved or viremic HCV infection. Measurement of systemic biomarkers in co-infection could help define the mechanism of inflammation on fibrosis and determine if HIV control reduces liver pathology. A nested case-control study was performed to explore the relationship of systemic biomarkers of inflammation with liver fibrosis in HCV viremic and/or seropositive women with and without HIV infection. Serum cytokines, chemokines, growth factors and cell adhesion molecules were measured in HIV uninfected (HIV-, n = …

A Critical Appraisal Of Extracorporeal Photopheresis As A Treatment Modality For Acute And Chronic Graft-Versus-Host Disease, Hind Rafei, Mohamed Kharfan-Dabaja, Taiga Nishihori

Medicine Faculty Publications

Although significant advances have been made in the biologic understanding of graft-versus-host disease (GVHD) and its treatment options, GVHD remains the single most challenging obstacle to the success of allogeneic hematopoietic cell transplantation (HCT) due to high risk of disabling morbidity and mortality. Extracorporeal photopheresis (ECP) has promising effects in controlling steroid-refractory GVHD, both acute and chronic, and it has been studied extensively. Its putative immunomodulatory mechanisms, while not immunosuppressive, position ECP as an attractive treatment strategy for GVHD patients who are already receiving global immunosuppression. However, ECP is relatively underutilized due in part to limited access and time commitment. …

Sustained Nitric Oxide-Releasing Nanoparticles Interfere With Methicillin-Resistant Staphylococcus Aureus Adhesion And Biofilm Formation In A Rat Central Venous Catheter Model., Mircea Radu Mihu, Vitor Cabral, Rodney Pattabhi, Moses T Tar, Kelvin P Davies, Adam J Friedman, Luis R Martinez, Joshua D Nosanchuk

Dermatology Faculty Publications

Staphylococcus aureus is frequently isolated in the setting of infections of indwelling medical devices, which are mediated by the microbe's ability to form biofilms on a variety of surfaces. Biofilm-embedded bacteria are more resistant to antimicrobial agents than their planktonic counterparts and often cause chronic infections and sepsis, particularly in patients with prolonged hospitalizations. In this study, we demonstrate that sustained nitric oxide-releasing nanoparticles (NO-np) interfere with S. aureus adhesion and prevent biofilm formation on a rat central venous catheter (CVC) model of infection. Confocal and scanning electron microscopy showed that NO-np-treated staphylococcal biofilms displayed considerably reduced thicknesses and bacterial …

Ptpro Represses Erbb2-Driven Breast Oncogenesis By Dephosphorylation And Endosomal Internalization Of Erbb2., H Dong, L Ma, J Gan, W Lin, Rakesh Kumar, +9 Additional Authors

Biochemistry and Molecular Medicine Faculty Publications

The plasma membrane-associated tyrosine phosphatase PTPRO is frequently transcriptionally repressed in cancers and signifies poor prognosis of breast cancer patients. In this study, deletion of Ptpro inMMTV-Erbb2 transgenic mice dramatically shortened the mammary tumor latency and accelerated tumor growth due to loss of Ptpro within the breast cancer cells but not in surrounding tissue as confirmed by hetero-transplantation studies. Both in vitro and in vivo data demonstrated that the phosphatase activity was required for the inactivation of ERBB2 and its downstream signaling. PTPRO regulated the phosphorylation status of ERBB2 at Y1248. Co-immunoprecipitation and proximity ligation assay (Duolink) indicated that …

A Fashi Lymphoproliferative Phenotype Reveals Non-Apoptotic Fas Signalling In Htlv-1-Associated Neuroinflammation., Soraya Maria Menezes, Fabio E Leal, Tim Dierckx, Ricardo Khouri, Daniele Decanine, Gilvaneia Silva-Santos, +Several Additional Authors

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Human T-cell lymphotropic virus (HTLV)-1 was the first human retrovirus to be associated to cancer, namely Adult T-cell Leukemia (ATL), but its pathogenesis remains enigmatic, since only a minority of infected individuals develops either ATL or the neuroinflammatory disorder HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). A functional FAS -670 polymorphism in an interferon (IFN)-regulated STAT1-binding site has been associated to both ATL and HAM/TSP susceptibility. Fashi T stem cell memory (Tscm) cells have been identified as the hierarchical apex of ATL, but have not been investigated in HAM/TSP. In addition, both FAS and STAT1 have been identified in an IFN-inducible HAM/TSP …

Nasopharyngeal Microbiome Diversity Changes Over Time In Children With Asthma, Marcos Pérez-Losada, Lamia Alamri, Keith Crandall, Robert J. Freishtat

Pediatrics Faculty Publications

Background

The nasopharynx is a reservoir for pathogens associated with respiratory illnesses such as asthma. Next-generation sequencing (NGS) has been used to characterize the nasopharyngeal microbiome of infants and adults during health and disease; less is known, however, about the composition and temporal dynamics (i.e., longitudinal variation) of microbiotas from children and adolescents. Here we use NGS technology to characterize the nasopharyngeal microbiomes of asthmatic children and adolescents (6 to 18 years) and determine their stability over time.

Methods

Two nasopharyngeal washes collected 5.5 to 6.5 months apart were taken from 40 children and adolescents with asthma living in the …

Perspectives On Model Forecasts Of The 2014–2015 Ebola Epidemic In West Africa: Lessons And The Way Forward, Gerardo Chowell, Cecile Viboud, Lone Simonsen, Stefano Merler, Alessandro Vespignani

Global Health Faculty Publications

The unprecedented impact and modeling efforts associated with the 2014–2015 Ebola epidemic in West Africa provides a unique opportunity to document the performances and caveats of forecasting approaches used in near-real time for generating evidence and to guide policy. A number of international academic groups have developed and parameterized mathematical models of disease spread to forecast the trajectory of the outbreak. These modeling efforts often relied on limited epidemiological data to derive key transmission and severity parameters, which are needed to calibrate mechanistic models. Here, we provide a perspective on some of the challenges and lessons drawn from these efforts, …
