BACKGROUND Venezuelan equine encephalitis virus (VEEV) belongs to the Alphavirus group. Several species of this family are also pathogenic to humans and are recognized as potential agents of biological warfare and terrorism. The objective of this work was the generation of recombinant antibodies for the detection of VEEV after a potential bioterrorism assault or an natural outbreak of VEEV. R...
Host antibody response is a crucial defense against pathogenic infection. Here, we report a novel technique allowing quantitative measurement of polyclonal antibody response in vivo. This involves expression of a combinatorial library of target proteins from a candidate pathogen on the surface of yeast Saccharomyces cerevisiae. After mixing with serum/plasma from infected or immunized subjects,...
Clinical trials using monoclonal antibodies (mAb) against cell-surface markers have yielded encouraging therapeutic results in several cancer types. Generally, however, anticancer antibodies are only efficient against a subpopulation of cancers, and there is a strong need for identification of novel targets and human antibodies against them. We have isolated single-chain human mAbs from a large...
Abstract Vaccines and therapeutics are urgently needed for the pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Here, we screen human monoclonal antibodies (mAb) targeting receptor binding domain (RBD) of viral spike protein via antibody library constructed from peripheral blood mononuclear cells a convalescent patient. The CT-P59 mAb potently neutralizes SARS-Co...
The adaptive immune system confers protection by generating a diverse repertoire of antibody receptors that are rapidly expanded and contracted in response to specific targets. Next-generation DNA sequencing now provides the opportunity to survey this complex and vast repertoire. In the present work, we describe a set of tools for the analysis of antibody repertoires and their application to el...
We describe here a method, based on iterative colony filter screening, for the rapid isolation of binding specificities from a large synthetic repertoire of human antibody fragments in single-chain Fv configuration. Escherichia coli cells, expressing the library of antibody fragments, are grown on a porous master filter, in contact with a second filter coated with the antigen, onto which antibo...
The major route of iron uptake by cells occurs through transferrin receptor (TfR)-mediated endocytosis of diferric-charged plasma transferrin (holo-Tf). In this work, we pursued TfR antibodies as potential cancer therapeutics, characterizing human single-chain variable antibody fragments (scFv) specific for the human TfR isolated from a phage display library. We hypothesized that many of these ...
BACKGROUND Aspergillus fumigatus is a common airborne fungal pathogen for humans. It frequently causes an invasive aspergillosis (IA) in immunocompromised patients with poor prognosis. Potent antifungal drugs are very expensive and cause serious adverse effects. Their correct application requires an early and specific diagnosis of IA, which is still not properly achievable. This work aims to a ...
