Convalescent human plasma candidate reference materials protect against Crimean-Congo haemorrhagic fever virus (CCHFV) challenge in an A129 mouse model

Frank William Charlton

Crimean-Congo Haemorrhagic Fever Virus (CCHFV) is spread by infected ticks or direct contact with blood, tissues and fluids from infected patients or livestock. Infection with CCHFV causes severe haemorrhagic fever in humans which is fatal in up to 83 % of ...

Glycan heterogeneity as a cause of the persistent fraction in HIV-1 neutralization

Aleksandar Antanasijevic, Philippe André Guy Colin

Neutralizing antibodies (NAbs) to multiple epitopes on the HIV-1-envelope glycoprotein (Env) have been isolated from infected persons. The potency of NAbs is measured more often than the size of the persistent fraction of infectivity at maximum neutralizat ...

Host-Pathogen Interactions Through the Genomic Lens

Zhi Ming Xu

Hosts and pathogens are involved in a long-standing evolutionary arms race characterized by successive rounds of evolution. Specifically, while hosts evolve resistance against infections, pathogens adapt to re-establish virulence. Since the signatures of t ...

A high-throughput cell- and virus-free assay shows reduced neutralization of SARS-CoV-2 variants by COVID-19 convalescent plasma

Didier Trono, Priscilla Turelli, Florence Pojer, Valeria Cagno, Charlène Mireille Raymonde Raclot, Jérémy Campos

The detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific antibodies in the serum of an individual indicates previous infection or vaccination. However, it provides limited insight into the protective nature of this immune resp ...

Immune serum-activated human macrophages coordinate with eosinophils to immobilize Ascaris suum larvae

Nicola Harris, Beatrice Volpe, Tiffany Babette Angélique Bouchery, Julia Esser-von Bieren, Kathleen Shah

Helminth infection represents a major health problem causing approximately 5 million disability-adjusted life years worldwide. Concerns that repeated anti-helminthic treatment may lead to drug resistance render it important that vaccines are developed but ...

Functional de novo Protein Design for Targeted Vaccines and Synthetic Biology Applications

Che Yang

Evolution has created, selected and evolved large repertoires of proteins that operate in various biological systems. Nowadays biotechnological needs are coming up orders of magnitude faster than proteins naturally evolve. The emergence of de novo protein ...

Role of myeloid cells in mediating protection against parasitic helminth larvae

Beatrice Volpe

Helminth infections affect around one fourth of the world population living in the poorest regions of our planet. Helminths mainly cause debilitating chronic effects on health, development and nutritional status of infected people. The development of a vac ...

The memristive effect as a novelty in drug monitoring

Giovanni De Micheli, Sandro Carrara, Ioulia Tzouvadaki, Nima Aliakbarinodehi

Nanoscale devices exhibiting memristive properties show great potential in a plethora of applications. In this work, memristive nanowires are presented for the first time as ideal candidates for absolutely novel, ultrasensitive, highly specific and selecti ...

Immune Antibodies and Helminth Products Drive CXCR2-Dependent Macrophage-Myofibroblast Crosstalk to Promote Intestinal Repair

Nicola Harris, Beatrice Volpe, Julia Esser-von Bieren, Duncan-Bruce Sutherland, Jérôme Bürgi

Helminth parasites can cause considerable damage when migrating through host tissues, thus making rapid tissue repair imperative to prevent bleeding and bacterial dissemination particularly during enteric infection. However, how protective type 2 responses ...

Antibody-Mediated Trapping of Helminth Larvae Requires CD11b and Fc gamma Receptor I

Nicola Harris, Romain Guiet, Arne Seitz, Beatrice Volpe, Julia Esser-von Bieren, Duncan-Bruce Sutherland, Manuel Kulagin

Infections with intestinal helminths severely impact on human and veterinary health, particularly through the damage that these large parasites inflict when migrating through host tissues. Host immunity often targets the motility of tissue-migrating helmin ...

Encapsulated Cellular Implants for Recombinant Protein Delivery and Therapeutic Modulation of the Immune System

Bernard Schneider, Aurélien Lathuilière

Ex vivo gene therapy using retrievable encapsulated cellular implants is an effective strategy for the local and/or chronic delivery of therapeutic proteins. In particular, it is considered an innovative approach to modulate the activity of the immune syst ...

Pathogen-free husbandry conditions alleviate behavioral deficits and neurodegeneration in AD10 anti-NGF mice

Maria del Carmen Sandi Perez, Daniel Constam, Stamatina Tzanoulinou

It has been suggested that systemic infection, occurring during aging and chronic neurodegenerative diseases, can evoke an immune response that aggravates the progression of neurodegeneration and cognitive decline. It has been shown that the AD11 neurodege ...

Efficient voltammetric discrimination of free bilirubin from uric acid and ascorbic acid by a CVD nanographite-based microelectrode

Giovanni De Micheli, László Forró, Sandro Carrara, Arnaud Magrez, Irene Taurino

We report a novel electrochemical sensor based on nanographite grown on platinum microelectrodes for the determination of bilirubin in the presence of normal concentrations of albumin. The albumin is a protein with an intrinsic ability to bind the bilirubi ...

Antibodies and IL-3 support helminth-induced basophil expansion

Nicola Harris, Mario Michael Zaiss, Julia Esser-von Bieren, Tina Herbst, Manuel Kulagin

Basophils are powerful mediators of Th2 immunity and are present in increased numbers during allergic inflammation and helminth infection. Despite their ability to potentiate Th2 immunity the mechanisms regulating basophil development remain largely unknow ...

Total serum IgE quantification by microfluidic ELISA using magnetic beads

Hubert Girault, Anne-Laure Gassner

The present work reports on the quantification of total IgE in human serum using a microanalytical device whose fluidics is driven by gravity and capillary forces only. Thanks to the eight parallel microchannels in each microchip, calibration and sample an ...

Immunoisolated cell implants for intracerebral delivery of anti-Aß single chain Fv antibodies in the APP23 Alzheimer's mouse model

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease in the elderly population. AD currently affects approximately 27 million people worldwide. A pathological hallmark of AD is the accumulation and deposition of the amyloid beta (Aβ) pe ...

Genome plasticity of BCG and impact on vaccine efficacy

Stewart Cole

To understand the evolution, attenuation, and variable protective efficacy of bacillus Calmette-Guérin (BCG) vaccines, Mycobacterium bovis BCG Pasteur 1173P2 has been subjected to comparative genome and transcriptome analysis. The 4,374,522-bp genome conta ...
