NaLi-H1: A universal synthetic library of humanized nanobodies providing highly functional antibodies and intrabodies
Jean-Christophe Rain, Laetitia Ligat, Ario de Marco, Emilie Lemesre, Laura Keller, Virginie Bernard, Nicolas Bery, Sandrine Moutel, Gilles Fevre, Aurelien Olichon, Franck Perez, 2016, izvirni znanstveni članek

Opis: In vitro selection of antibodies allows to obtain highly functional binders, rapidly and at lower cost. Here, we describe the first fully synthetic phage display library of humanized llama single domain antibody (NaLi-H1: Nanobody Library Humanized 1). Based on a humanized synthetic single domain antibody (hs2dAb) scaffold optimized for intracellular stability, the highly diverse library provides high affinity binders without animal immunization. NaLi-H1 was screened following several selection schemes against various targets (Fluorescent proteins, actin, tubulin, p53, HP1). Conformation antibodies against active RHO GTPase were also obtained. Selected hs2dAb were used in various immunoassays and were often found to be functional intrabodies, enabling tracking or inhibition of endogenous targets. Functionalization of intrabodies allowed specific protein knockdown in living cells. Finally, direct selection against the surface of tumor cells produced hs2dAb directed against tumor-specific antigens further highlighting the potential use of this library for therapeutic applications.

Molecular dynamics simulations and docking enable to explore the biophysical factors controlling the yields of engineered nanobodies
Ario de Marco, Miguel Soler, Sara Fortuna, 2016, izvirni znanstveni članek

Opis: Nanobodies (VHHs) have proved to be valuable substitutes of conventional antibodies for molecular recognition. Their small size represents a precious advantage for rational mutagenesis based on modelling. Here we address the problem of predicting how Camelidae nanobody sequences can tolerate mutations by developing a simulation protocol based on all-atom molecular dynamics and wholemolecule docking. The method was tested on two sets of nanobodies characterized experimentally for their biophysical features. One set contained point mutations introduced to humanize a wild type sequence, in the second the CDRs were swapped between single-domain frameworks with Camelidae and human hallmarks. The method resulted in accurate scoring approaches to predict experimental yields and enabled to identify the structural modifications induced by mutations. This work is a promising tool for the in silico development of single-domain antibodies and opens the opportunity to customize single functional domains of larger macromolecules

Nanobodies against surface biomarkers enable the analysis of tumor genetic heterogeneity in uveal melanoma Patient Derived Xenografts

Opis: Monoclonal antibodies specific for biomarkers expressed on the surface of uveal melanoma (UM) cells would simplify the immune-capture and genomic characterization of heterogeneous tumor cells originated from patient derived xenografts (PDXs). Antibodies against four independent tumor antigens were isolated by panning a nanobody synthetic library. Such antibodies enabled flow-cytometry-based sorting of distinct cell sub-populations from UM PDXs and to analyze their genomic features. The complexity and specificity of the biochemical and genomic biomarker combinations mirrored the UM tumor polyclonality. The data showed that MUC18 is highly and universally displayed at the surface of UM cells with different genetic background and consequently represents a reliable pan-biomarker for their identification and purification. In contrast, the other three biomarkers were detected in very variable combinations in UM PDX cells. The availability of the identified nanobodies will be instrumental in developing clone-specific drug evaluation and rational clinical strategies based on accurate genomic profiling

Nanobody technology: principles & applications
Ario De Marco, predavanje na tuji univerzi

Opis: Antibodies possess unattainable capacity to bind selectively and at high affinity their cognates. For this reason they have been largely used in applications which rely on specific molecular recognition. Biosensors, nanoparticles, and even cells can be functionalized with antibodies for improving sensitivity and target specificity. However, conventional antibodies (IgGs) are large molecules (150 kDa) that are difficult to engineer. In the last years, antibody fragments have become more and more popular as an effective alternative and specifically nanobodies raised enthusiasm because of their minimal mass (14 kDa), high stability, relative similarity to human sequences, and simplified mutagenesis. Pre-immune nanobody libraries have the further advantage of enabling blind selection for antigens that can be used to discriminate between subpopulations of cells and vesicles. The panning can be performed directly on intact cells and the resulting binders are specific for the native antigen conformation
