Enhancing the Protein Stability of an Anticancer VHH‐Fc Heavy Chain Antibody through Computational Modeling and Variant Design

Advanced Science, EarlyView.
In this study, a computational pipeline is developed to systematically evaluate the conformational stability, disulfide bond reduction state, and aggregation and degradation tendencies of an anticancer VHH‐Fc fusion antibody. Based on the mechanistic insights, antibody variants with enhanced stability and increased yield are successfully designed. This

Application of humanized mice in the safety experiments of antibody drugs

Animal Models and Experimental Medicine, EarlyView.
The graphical abstract of this review highlights the critical role of humanized mice in the safety evaluation of antibody drugs. First, the inherent immunogenicity of antibody drugs can lead to the production of antidrug antibodies and hypersensitivity reactions on repeated administration.

Selection of IgG variants with increased FcRn binding using random and directed mutagenesis: impact on effector functions

Frontiers in Immunology, 2015
Despite the reasonably long half-life of IgGs, market pressure for higher patient convenience while conserving efficacy continues to drive IgG half-life improvement.

Podocyte-specific knockout of the neonatal Fc receptor (FcRn) results in differential protection depending on the model of glomerulonephritis.

PLoS ONE, 2020
Podocytes have been proposed to be antigen presenting cells (APCs). In traditional APCs, the neonatal Fc receptor (FcRn) is required for antigen presentation and global knockout of FcRn protects against glomerulonephritis.

Delanzomib, a Novel Proteasome Inhibitor, Combined With Adalimumab Drastically Ameliorates Collagen-Induced Arthritis in Rats by Improving and Prolonging the Anti-TNF-α Effect of Adalimumab

Frontiers in Pharmacology, 2021
Delanzomib is a novel proteasome inhibitor initially developed for treating multiple myeloma. It was found to inhibit the expression of tumor necrosis factor alpha (TNF-α). This study aimed to investigate the ameliorating effect of delanzomib on collagen-

Does a PESQNet (Loss) Require a Clean Reference Input? The Original PESQ Does, But ACR Listening Tests Don't [PDF]

arXiv, 2022
Perceptual evaluation of speech quality (PESQ) requires a clean speech reference as input, but predicts the results from (reference-free) absolute category rating (ACR) tests. In this work, we train a fully convolutional recurrent neural network (FCRN) as deep noise suppression (DNS) model, with either a non-intrusive or an intrusive PESQNet, where ...

Engineering antibodies with cancer‐associated binding sites

BMEMat, EarlyView.
This review describes antibodies that perform direct/indirect roles in cancer treatment by binding to effective targets and discusses how antibodies kill tumors and modulate tumor microenvironment through these targets. The classification of expression systems for antibody production is summarized to guide appropriate selection based on different ...

Regulation of immune responses by the neonatal Fc receptor and its therapeutic implications

Frontiers in Immunology, 2015
As a single receptor, the neonatal Fc receptor (FcRn) is critically involved in regulating albumin and IgG serum concentrations by protecting these two ligands from degradation.

The Fab region of IgG impairs the internalization pathway of FcRn upon Fc engagement

Nature Communications, 2022
Disrupting the association between the Immunoglobulin G constant fragment (Fc) and the neonatal Fc receptor (FcRn) by engineered antibodies is a promising strategy to reduce autoantibody levels in autoimmune diseases.

Engineering and Structural Elucidation of a Sac7d‐Derived IgG Fc‐Specific Affitin and Its Application for the Light‐Controlled Affinity Purification of Antibodies

ChemBioChem, EarlyView.
An affitin derived from the Sac7d scaffold enables the light‐controlled affinity purification of antibodies under physiological conditions, thus overcoming limitations of protein A chromatography. X‐ray crystallographic analysis and affinity measurements reveal complex formation with Fc at the CH2/CH3 junction, similar to protein A/G and FnRn. Combined
