4C3 Human Monoclonal Antibody: A Proof of Concept for Non-pathogenic Proteinase 3 Anti-neutrophil Cytoplasmic Antibodies in Granulomatosis With Polyangiitis
Granulomatosis with polyangiitis (GPA) is a severe autoimmune vasculitis associated with the presence of anti-neutrophil cytoplasmic antibodies (ANCA) mainly targeting proteinase 3 (PR3), a neutrophilic serine proteinase. We obtained for the first time a non-activating human IgG1κ anti-PR3 monoclonal antibody (mAb) named 4C3. This new mAb binds soluble PR3 with a high affinity and membrane-bound PR3 on an epitope close to the PR3 hydrophobic patch and in the vicinity of the active site.

MAbSilico deploys its AI tools for a fast response in context of pandemic threat
The use of MAbSilico technologies accelerates the development of antibodies drug candidates against SARS-CoV-2
In the context of the Covid-19 crisis, MAbSilico deploys its AI technologies to develop faster antibody drug candidates against SARS-CoV-2. Within a group of experts gathered around MAbSilico, the use of two tools is engaged to deliver candidates in a few weeks:
i/The antibody maturation with MAbMature® method is used to convert anti-SARS-CoV antibodies into anti-SARS-CoV2 antibodies (cf figure, strategy 1). Previously described anti-SARS-Co-V antibodies have already been identified, like the one shown in the figure which inhibits the binding of the spike protein on its receptor ACE2 and subsequent viral entry in its target cells. The comparison between the scFv epitopes on the spike proteins of SARS-CoV and SARS-CoV-2 (this latter one being defined by MAbSilico’s method MAbTope®) shown that the homology between the 2 proteins in the VL interface is too low to predict an actual binding of the scFv on SARS-CoV-2 spike. MAbMature® method is thus applied only to the VH domain which matured CDRs are illustrated in red.
ii/ The antibody selection method MAbSelect® (cf figure, strategy 2) which combines MAbSilico’s similarity-based antibody clustering and affinity prediction methods in the aim of retrieving anti-SARS-Cov2 antibodies from healed patients’ blood samples.
The antibodies drug candidates identified by both methods will be tested in vitro and in vivo.
By engaging these developments, MAbSilico creates a fast track and breakthrough pipeline for antibody drug candidates development to react to the next pandemics.

Biasing HER4 Tyrosine Kinase Signaling with Antibodies: Induction of Cell Death by antibody-dependent 4ICD Trafficking
In this paper, we demonstrated that Neuregulin 1 (NRG1) induces cell death through JMa/CYT1 HER4 retention into mitochondria, and selected anti-HER4 antibody C6 mimics these NRG1-induced effects leading to tumor growth regression of ovarian and breast cancer xenografts

Methods to Determine Interaction Interfaces Between β-Arrestins and Their Protein Partners
We present here a method in two steps: protein–protein docking allows finding a limited number of peptides predicted to be involved in the interaction, and then experimental approaches that might be used for validating the prediction.

G protein–dependent signaling triggers a β-arrestin–scaffolded p70S6K/ rpS6 module that controls 5′TOP mRNA translation
This work highlights new relationships between G proteins and β-arrestins when acting cooperatively on a common signaling pathway, contrasting with their previously shown parallel action on the ERK MAP kinase pathway. In addition, this study provides insights into how GPCR can exert trophic effects in the cell.
