A Review of the Current Status of Percutaneous Endovascular Arteriovenous Fistula Creation for Haemodialysis Access.

Surgical fistulas were first described over 50 years ago and have revolutionized the outlook for millions of dialysis-dependent patients. Despite many developments, results remain sub-optimal with high rates of primary failure and re-intervention to maintain patency. Surgical fistulas are known to fail in part due to intimal hyperplasia leading to stenosis, and vessel manipulation during anastomosis creation can be contributory. New technology is emerging that allows the endovascular creation of fistulas w...

All Aboard! Enteric Viruses Travel Together.

Individual virus particles have long been accepted as the infectious unit during cellular infection and host-to-host transmission. In this issue of Cell Host & Microbe, Santiana et al. (2018) uncover vesicle-cloaked rotavirus and norovirus clusters in feces of infected hosts that are more infectious than free virus particles during fecal-oral transmission.

Budding of Ebola Virus Particles Requires the Rab11-Dependent Endocytic Recycling Pathway.

The Ebola virus-encoded major matrix protein VP40 traffics to the plasma membrane, which leads to the formation of filamentous viral particles and subsequent viral egress. However, the cellular machineries underlying this process are not fully understood. In the present study, we have assessed the role of host endocytic recycling in Ebola virus particle formation. We found that a small GTPase Rab11, which regulates recycling of molecules among the trans-Golgi network, recycling endosomes, and the plasma mem...

Unveiling the RNA virosphere associated with marine microorganisms.

The study of extracellular DNA viral particles in the ocean is currently one of the most advanced fields of research in viral metagenomic analysis. However, even though the intracellular viruses of marine microorganisms might be the major source of extracellular virus particles in the ocean, the diversity of these intracellular viruses is not well understood. Here, our newly developed method, referred to herein as fragmented and primer ligated dsRNA sequencing (flds) version 2, identified considerable genet...

Incorporation of CD40 ligand or granulocyte-macrophage colony stimulating factor into Hantaan virus (HTNV) virus-like particles significantly enhances the long-term immunity potency against HTNV infection.

Hantavirus infections cause severe haemorrhagic fever with renal syndrome (HFRS) in humans and are associated with high fatality rates. In 2017, numerous outbreaks were reported in China and Germany. This represents a significant public-healthcare issue with no effective HFRS vaccines that offer a long-term immune response. In this study, we investigated the long-term humoral and cellular immune responses and protective immunity of Hantaan virus (HTNV) granulocyte-macrophage colony stimulating factor (GM-CS...

Self-assembly and stabilization of hybrid cowpea chlorotic mottle virus particles under nearly physiological conditions.

Capsids of the cowpea chlorotic mottle virus (CCMV) hold great promise for use as nanocarriers in vivo. A major drawback, however, is the lack of stability of the empty wild-type virus particles under physiological conditions. Here, we report on the assembly behavior and stability under nearly-physiological conditions of protein-based block copolymers composed of the CCMV capsid protein and two hydrophobic elastin-like polypeptides. UV-vis spectrometric studies, dynamic light scattering analysis, and transm...

The struggle for existence in the world market ecosystem.

The global trade system can be viewed as a dynamic ecosystem in which exporters struggle for resources: the markets in which they export. We can think that the aim of an exporter is to gain the entirety of a market share (say, car imports from the United States). This is similar to the objective of an organism in its attempt to monopolize a given subset of resources in an ecosystem. In this paper, we adopt a multilayer network approach to describe this struggle. We use longitudinal, multiplex data on trade ...

Human immunodeficiency virus status in malnourished children seen at Lagos.

Human immunodeficiency virus and protein energy malnutrition are still prevalent in Nigeria and the occurrence of the two conditions together confers a poor prognosis. The aim of this study was to determine the current categories of malnutrition amongst under-5 children in Lagos, document their HIV status and determine any peculiarities in the clinical features, haematological and some biochemical profile in these children.

The parts are greater than the whole: the role of semi-infectious particles in influenza A virus biology.

The influenza A virus (IAV) genome is incorporated into newly produced virions through a tightly orchestrated process that is one of the best studied examples of genome packaging by a segmented virus. Despite the remarkable selectivity and efficiency of this process, it is clear that the vast majority of IAV virions are unable to express the full set of essential viral gene products and are thus incapable of productive replication in the absence of complementation. Here, we attempt to reconcile the widespre...

Highly Sensitive Glycan Profiling of Hepatitis B Viral Particles and a Simple Method for Dane Particle Enrichment.

Hepatitis B virus (HBV) is a double-stranded DNA virus composed of three types of viral particles. The virions are called Dane particles and the others are non-infectious sub-viral particles (SVPs). In blood, SVPs are detected in abundance, about 1,000-10,000 fold higher than Dane particles. Dane particles are hazardous owing to their strong infectivity, unlike SVPs. Dane particles are covered with an envelope of glycoprotein called HBV surface antigen (HBsAg). HBsAg glycosylation is involved in viral parti...

HSP70 Copurifies with Zika Virus Particles.

Zika virus (ZIKV) has been identified as a cause of neurologic diseases in infants and Guillain-Barré Syndrome, and currently, no therapeutics or vaccines are approved. In this study, we sought to identify potential host proteins interacting with ZIKV particles to gain better insights into viral infectivity. Viral particles were purified through density-gradient centrifugation and subsequently, size-exclusion chromatography (SEC). Mass spectrometric analyses revealed viral envelope protein and HSP70 to c...

Efficient support of virus-like particle assembly by the HIV-1 packaging signal.

The principal structural component of a retrovirus particle is the Gag protein. Retroviral genomic RNAs contain a 'packaging signal' ('Ψ') and are packaged in virus particles with very high selectivity. However, if no genomic RNA is present, Gag assembles into particles containing cellular mRNA molecules. The mechanism by which genomic RNA is normally selected during virus assembly is not understood. We previously reported (Comas-Garcia et al., 2017) that at physiological ionic strength, recombinant HIV-1 ...

Flu Shows the Power of Diversity.

Morphological variation is a common yet poorly understood feature of influenza virus populations. Vahey and Fletcher reveal that the production of physically and phenotypically heterogeneous particles is an inherent feature of the influenza assembly process that may promote virus survival in challenging environments.

Targeted Elimination of Tumorigenic Human Pluripotent Stem Cells Using Suicide-inducing Virus-like Particles.

Sensitization to prodrugs via transgenic expression of suicide genes is a leading strategy for the selective elimination of potentially tumorigenic human pluripotent stem cells (hPSCs) in regenerative medicine, but transgenic modification poses safety risks such as deleterious mutagenesis. We describe here an alternative method of delivering suicide-inducing molecules explicitly to hPSCs using virus-like particles (VLPs), and demonstrate its use in eliminating undifferentiated hPSCs in vitro. VLPs were engi...

An in vitro and in vivo study on the properties of hollow polycaprolactone cell-delivery particles.

The field of dermal fillers is evolving rapidly and numerous products are currently on the market. Biodegradable polymers such as polycaprolactone (PCL) have been found to be compatible with several body tissues, and this makes them an ideal material for dermal filling purposes. Hollow PCL spheres were developed by the Council for Scientific and Industrial Research (CSIR) to serve both as an anchor point and a "tissue harbour" for cells. Particles were tested for cytotoxicity and cell adherence using mouse ...

Structural analysis of influenza vaccine virus-like particles reveals a multicomponent organization.

Influenza virus continues to be a major health problem due to the continually changing immunodominant head regions of the major surface glycoprotein, hemagglutinin (HA). However, some emerging vaccine platforms designed by biotechnology efforts, such as recombinant influenza virus-like particles (VLPs) have been shown to elicit protective antibodies to antigenically different influenza viruses. Here, using biochemical analyses and cryo-electron microscopy methods coupled to image analysis, we report the com...

Virus-like particles (VLP) in prophylaxis and immunotherapy of allergic diseases.

Apart from active allergen avoidance, immunotherapy is regarded as the most effective form of treatment available for type I allergies. Such treatments involve the administration of allergen preparations in various forms and by various routes. Virus-like particles (VLPs) offer a very effective platform for immunization with the allergen and are characterized by high immunogenicity, low allergenicity and high clinical efficacy. Formulations that include Toll-like receptor ligands, T cell stimulatory epito...

The Molecular Mechanism of Externalization of Phosphatidylserine on the Surface of Ebola Virus Particles.

Ebola virus (EBOV) is an enveloped filamentous virus that causes severe hemorrhagic fever in humans and nonhuman primates with up to 90% fatality. Accumulating evidence indicates that various viruses, including EBOV, exploit the host apoptotic clearance machinery to enhance their entry into host cells by externalizing phosphatidylserine (PS) in the viral envelope. PS is typically distributed in the inner layer of the plasma membrane (PM) in normal cells. Progeny EBOV virions bud from the PM of infected cell...
