Infection with Schistosoma causes aberrant expression of host microRNAs (miRNAs), and normalizing the levels of dysregulated miRNAs can attenuate pathology. Here, we show that the host miRNA, miR-96, is markedly upregulated during the progression of hepatic schistosomiasis. We demonstrate that elevation of miR-96 induces hepatic fibrosis in infected mice by suppressing the expression of its target gene, Smad7. We show that infection with Schistosoma induces the expression of transforming growth factor beta1 (TGF-beta1), which in turn upregulates the expression of miR-96 through SMAD2/3-DROSHA-mediated post-transcriptional regulation. Furthermore, inhibition of miR-96 with recombinant adeno-associated virus 8 (rAAV8)-mediated delivery of Tough ...

Necroptosis is a pro-inflammatory cell death, which happens in the context of caspase-8 inhibition, allowing activation of the receptor interacting protein kinase 1-receptor interacting protein kinase 3-mixed lineage kinase domain-like (RIPK1-RIPK3-MLKL) axis. Recently, necroptosis has emerged as a key component of resistance against pathogens including infected macrophage by Leishmania infantum, the ethiologic agent of Visceral leishmaniasis (VL). VL is the most severe form of Leishmaniasis, characterized by systemic inflammation and neutropenia. However, the role of neutrophil cell death in VL has not been characterized. Here, we showed that VL patients exhibited increased lactate dehydrogenase levels in the serum, a hallmark ...

Drug-Resistance And Population Structure Of Plasmodium Falciparum Across The Democratic Republic Of Congo Using High-Throughput Molecular Inversion Probes, Ozkan Aydemir, Nicholas J. Hathaway, Patrick W. Marsh, Alice Tran, Thomas Reimonn, Jeffrey A. Bailey

Open Access Articles

A better understanding of the drivers of the spread of malaria parasites and drug resistance across space and time is needed. These drivers can be elucidated using genetic tools. Here, a novel molecular inversion probe (MIP) panel targeting all major drug-resistance mutations and a set of microsatellites was used to genotype Plasmodium falciparum infections of 552 children from the 2013-2014 Demographic and Health Survey conducted in the Democratic Republic of the Congo (DRC). Microsatellite-based analysis of population structure suggests that parasites within the DRC form a homogeneous population. In contrast, sulfadoxine-resistance markers in dihydropteroate synthase show marked spatial structure with ...

Hookworms are intestinal nematode parasites that infect nearly half a billion people and are globally one of the most important contributors to iron-deficiency anemia. These parasites have significant impacts in developing children, pregnant women and working adults. Of all the soil-transmitted helminths or nematodes (STNs), hookworms are by far the most important, with disease burdens conservatively estimated at four million DALYs (Disability-Adjusted Life Years) and with productivity losses of up to US$139 billion annually. To date, mainly one drug, albendazole is used for hookworm therapy in mass drug administration, which has on average approximately 80% cure rate that is ...

In Vivo And In Vitro Studies Of Cry5b And Nicotinic Acetylcholine Receptor Agonist Anthelmintics Reveal A Powerful And Unique Combination Therapy Against Intestinal Nematode Parasites, Yan Hu, Melanie Miller, Bo Zhang, Thanh-Thanh Nguyen, Martin K. Nielsen, Raffi V. Aroian

Open Access Articles

BACKGROUND: The soil-transmitted nematodes (STNs) or helminths (hookworms, whipworms, large roundworms) infect the intestines of ~1.5 billion of the poorest peoples and are leading causes of morbidity worldwide. Only one class of anthelmintic or anti-nematode drugs, the benzimidazoles, is currently used in mass drug administrations, which is a dangerous situation. New anti-nematode drugs are urgently needed. Bacillus thuringiensis crystal protein Cry5B is a powerful, promising new candidate. Drug combinations, when properly made, are ideal for treating infectious diseases. Although there are some clinical trials using drug combinations against STNs, little quantitative and systemic work has been performed to define ...

Comparing The Efficacy Of Copper Oxide Wire Particles And Copper Sulfate On Haemonchus Contortus In Goats, James Mackey 2018 Murray State University

Comparing The Efficacy Of Copper Oxide Wire Particles And Copper Sulfate On Haemonchus Contortus In Goats, James Mackey

Honors College Theses

This is a comparative study on the anthelmintic effects of copper oxide wire particles (COWP), copper sulfate (CuSO4), and Levamisole on Haemonchus contortus in goats. This study was designed to compare the efficiency of COWP and CuSO4 at controlling H. contortus populations in goats. A study group of 60 female goats was randomly separated into 3 groups. The does in each group were administered either a copper sulfate drench by weight, a Levamisole drench by weight, or a 4g bolus of COWP. Fecal egg counts and Faffa Malan Charts (FAMACHA), were performed every 2 weeks, and Packed Cell ...

BACKGROUND: Blood flukes of the genus Schistosoma cause schistosomiasis-a neglected tropical disease (NTD) that affects more than 200 million people worldwide. Studies of schistosome genomes have improved our understanding of the molecular biology of flatworms, but most of them have focused largely on protein-coding genes. Small non-coding RNAs (sncRNAs) have been explored in selected schistosome species and are suggested to play essential roles in the post-transcriptional regulation of genes, and in modulating flatworm-host interactions. However, genome-wide small RNA data are currently lacking for key schistosomes including Schistosoma haematobium-the causative agent of urogenital schistosomiasis of humans.

METHODOLOGY: MicroRNAs (miRNAs) and other ...

Can Prescribed Fire Reduce Tick Parasitism Of Birds?, Leslie A. Sterling, Kim Medley, Katie Westby, Solný Adalsteinsson

Undergraduate Research Symposium Posters

Tick-borne diseases spread through enzootic transmission cycles that often involve ticks parasitizing bird hosts. Some avian species are competent reservoirs, amplifying the pathogens that cause tick-borne illnesses in humans. Prescribed burns in forests have the potential to reduce tick-borne disease risk if they limit interactions between ticks and infectious wildlife hosts. Although prescribed burns are increasingly being used for a variety of habitat management purposes, little is known about how they affect tick-host interactions. We hypothesize that if prescribed fires reduce tick abundance, then birds in burned forest plots will host fewer ticks than birds in unburned forest plots. Experimental ...

Evaluation Of The Carestarttm Glucose-6-Phosphate Dehydrogenase (G6pd) Rapid Diagnostic Test At Community And Health Center Level, Cambodia, Bertha Nyagaya-Wojnarski, DNP, FNP-BC, MPH 2018 George Washington University

Evaluation Of The Carestarttm Glucose-6-Phosphate Dehydrogenase (G6pd) Rapid Diagnostic Test At Community And Health Center Level, Cambodia, Bertha Nyagaya-Wojnarski, Dnp, Fnp-Bc, Mph

Doctor of Nursing Practice Projects

Background: Primaquine (PQ) is the only FDA-approved drug for radical cure of Plasmodium vivax (P.v) malaria, but treatment can result in life-threatening hemolysis if given to a glucose-6- phosphate dehydrogenase deficient (G6PDd) patient. Therefore, the G6PD status of the patient with P.v must be known prior to prescribing PQ. However, patient G6PD status in rural malaria endemic settings is generally unknown, illuminating the need for reliable point of care G6PD diagnostic tests as a prerequisite to safely administer PQ. To increase community PQ access in Cambodia, performance of CareStartTM G6PD rapid diagnostic tests (RDTs) needs to be evaluated ...

Chad63 Cs And Mva Cs, Novel Malaria Vaccine Candidates, Eoghan De Barra

MD theses

Plasmodium falciparum (P. falciparum) malaria remains a significant cause of mortality and morbidity throughout the world. Development of an effective vaccine would be key intervention to reduce the considerable social and economic impact of malaria. Following review of previous work on malaria vaccines, we conducted a Phase Ia, non-randomized clinical trial in 24 healthy, malaria-naïve adults of the chimpanzee adenovirus 63 (ChAd63) and modified vaccinia virus Ankara (MVA) replication-deficient viral vectored vaccines encoding the circumsporozoite protein (CS) of P. falciparum. ChAd63-MVA CS administered in a heterologous prime-boost regime was shown to be safe and immunogenic, inducing high-level T cell responses ...


Down-Regulation Of Microrna-203-3p Initiates Type 2 Pathology During Schistosome Infection Via Elevation Of Interleukin-33, Xing He, Jun Xie, Yange Wang, Xiaobin Fan, Qin Su, Yue Sun, Nanhang Lei, Dongmei Zhang, Guangping Gao, Weiqing Pan 2018 Second Military Medical University

The type 2 immune response is the central mechanism of disease progression in schistosomiasis, but the signals that induce it after infection remain elusive. Aberrant microRNA (miRNA) expression is a hallmark of human diseases including schistosomiasis, and targeting the deregulated miRNA can mitigate disease outcomes. Here, we demonstrate that efficient and sustained elevation of miR-203-3p in liver tissues, using the highly hepatotropic recombinant adeno-associated virus serotype 8 (rAAV8), protects mice against lethal schistosome infection by alleviating hepatic fibrosis. We show that miR-203-3p targets interleukin-33 (IL-33), an inducer of type 2 immunity, in hepatic stellate cells to regulate the expansion and ...

Visceral leishmaniasis (VL) is a major public health issue reported as the second illness in mortality among all tropical diseases. Clinical trials have shown that protection against VL is associated with robust T cell responses, especially those producing IFN-gamma. The Leishmania amastigote 2 (A2) protein has been repeatedly described as immunogenic and protective against VL in different animal models; it is recognized by human T cells, and it is also commercially available in a vaccine formulation containing saponin against canine VL. Moving toward a more appropriate formulation for human vaccination, here, we tested a new optimized version of the recombinant ...
