Abstract

Single-domain antibodies (sdAbs) represent the minimal antigen binding-competent form of the immunoglobulin domain and have unique properties and applications. SdAbs are naturally produced as the variable domains of the heavy chain-only antibodies of camelid ruminants and cartilaginous fishes, but can also be engineered synthetically from autonomous human or mouse VH or VL domains. The scope of this research topic and associated e-book covers current understanding and new developments in (i) the biology, immunology and immunogenetics of sdAbs in camelids and cartilaginous fishes, (ii) strategies for sdAb discovery, (iii) protein engineering approaches to increase the solubility, stability and antigen-binding affinity of sdAbs and (iv) specialized applications of sdAbs in areas such diagnostics, imaging and therapeutics.

Abstract

Monoclonal antibodies and Fc-fusion proteins used clinically are Fc-based therapeutics that grow fastest in the pharmaceutical industry. Since they both contain an Fc fragment, engineering of Fc fragments could be a platform for improving Fc-based drug efficacy. Fc engineering includes various aspects: stabilization of Fc; regulation of effector functions including antibody-dependent cell-mediated cytotoxicity, complement-dependent cytotoxicity; extension of serum half-life by modification of neonatal Fc receptor (FcRn) binding; monomerization or heterodimerization of Fc for design of new Fc formats. Currently, many new methods are being used in Fc engineering. Compared to traditional methods such as site mutagenesis on certain positions by amino acid replacement, new methods such as display-based technology can confer high throughput screening and obtain optimized variants relatively quickly, accelerating the drug development process. With the new methods, many new Fc variants were identified. On this Research Topic we are going to review the progress in current Fc engineering including the new engineering methods and the Fc variants or constructs they have produced, and the potential of these new Fcs in clinical use.

Abstract

The high effectiveness of antibodies as anti-tumor therapeutic agents has led to a burst of research aiming to increase their therapeutic applications by the use of antibodies against new targets, new antibody formats or new combinations. In this e-book we present relevant research depicting the current efforts in the field.
