Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Characterization of Primate Antibody Responses to Administered Murine Monoclonal Immunoglobulin

The International Journal of Biological Markers, 1990
Murine monoclonal antibodies (MAb) are currently being assessed for their utility as tools in cancer management. Anti-murine immunoglobulin responses have been observed in many patients receiving monoclonal antibody treatment. In this study, we evaluated

Optimized Ex Vivo Human Liver Slice Culture Maintains Extended Viability and Function for Hepatotoxicity Testing

Advanced Science, EarlyView.
An optimized ex vivo human liver slice culture system preserves tissue architecture, hepatocyte function, and immune‐stromal complexity for at least five days. By refining slice thickness, oxygenation, air‐liquid interface, and extracellular matrix support, the platform enables human‐relevant hepatotoxicity testing and mechanistic studies, offering a ...

Engineering Antibodies into Targeted Chimeras: From Recognition Modules to Programmable Degraders

Advanced Science, EarlyView.
Antibody can be engineered into diverse lysosome‐targeting chimeras that convert target recognition into active degradation. By coupling antibody binding with recruited receptors, encoded domains, conjugated ligands, or nanoparticle scaffolds, these antibody‐associated targeted chimeras (AbTACs) platforms direct extracellular and membrane proteins ...

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

Advanced Science, EarlyView.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

Allosteric inhibition of IgE–FcεRI interactions by simultaneous targeting of IgE F(ab’)2 epitopes

Communications Biology
Immunoglobulin E (IgE) plays pivotal roles in allergic diseases through interaction with a high-affinity receptor (FcεRI). We established that Fab fragments of anti-IgE antibodies (HMK-12 Fab) rapidly dissociate preformed IgE-FcεRI complexes in a ...

A Synthetic Platform for Antibody Junctional Diversification Beyond Natural Constraints

Advanced Science, EarlyView.
ARESEC is a synthetic platform that reconstructs functional V(D)J recombination in HEK293T cells. By introducing RSS elements and co‐expressing RAG1/2 and TdT across all three antibody CDRs, it enables programmable junctional diversification and direct generation of high‐affinity variants targeting PD‐1/PD‐L1, overcoming the evolutionary constraints of
