This third volume of the Selected Works focusses on a detailed study of fraction Brownian motions. The fractal themes of "self-affinity" and "globality" are presented, while extensive introductory material, written especially for this book, precedes the papers and presents a number of striking new observations and conjectures. The mathematical tools so discussed will be valuable to diverse scientific communities.

T-cells are an essential component of the immune system that provide protection against pathogen infections and cancer and are involved in the aetiology of numerous autoimmune and autoinflammatory pathologies. Their importance in disease, the relative ease to isolate, expand and manipulate them ex vivo have put T-cells at the forefront of basic and translational research in immunology. Decades of study have shed some light on the unique way T-cells integrate extrinsic environmental cues influencing an activation program triggered by interactions between peptide-MHC complexes and the antigen-recognition machinery constituted of clonally distributed T-cell receptors and their co-receptor CD4 or CD8. The manipulation of these molecular determinants in cellular systems or as recombinant proteins has considerably enhanced our ability to understand antigen-specific T-cell activation, to monitor ongoing T-cell responses and to exploit T-cells for therapy. Even though these principles have given numerous insights in the biology of CD8+ T-cells that translate into promising therapeutic prospects, as illustrated by recent breakthroughs in cancer therapy, they have proven more challenging to apply to CD4+ T-cells. This Research Topic aims to provide a comprehensive view of the recent insights provided by the use of engineered antigen receptors and their ligands on T-cell activation and how they have been or could be harnessed to design efficient immunotherapies.

This volume presents discussions of theoretical and experimental considerations that have led to the analytical affinity chromatography field, as well as current efforts to use this methodology to characterize the interaction mechanisms of biological macromolecules and to establish conditions for employing bioaffinity chromatographic systems as preparative tools. The chapters include a comprehensive discussion of interactive chromatography theory (DeLisi and Hethcote), a review of experimental data obtained for biological macromolecules and the relevant theoretical considerations of affinity chromatography which led to them (Swaisgood and Chaiken), an evaluation of rate processes in affinity chromatography and the potential to determine biologically meaningful chemical rate constants (Walters), and the use of quantitative and molecular considerations to design affinity chromatographic systems (Stellwagen and Liu).
