The Comprehensive Sourcebook of Bacterial Protein Toxins, Fourth Edition, contains chapters written by internationally known and well-respected specialists. This book contains chapters devoted to individual toxins, as well as chapters that consider the different applications of these toxins. Considerable progress has been made in understanding the structure, function, interaction and trafficking into cells, as well as mechanism of action of toxins. Bacterial toxins are involved in the pathogenesis of many bacteria, some of which are responsible for severe diseases in human and animals, but can also be used as tools in cell biology to dissect cellular processes or used as therapeutic agents. Novel recombinant toxins are already proposed in the treatment of some diseases, as well as new vaccines. Alternatively, certain toxins are also considered as biological weapons or bioterrorism threats. Given the multifaceted aspects of toxin research and the multidisciplinary approaches adopted, toxins are of great interest in many scientific areas from microbiology, virology, cell biology to biochemistry and protein structure. This new edition is written with a multidisciplinary audience in mind and contains 5 new chapters that reflect the latest research in this area. Other chapters have been combined, deleted and fully revised as necessary to deliver relevant and valuable content.

Daniel Ladant is Director of Research at French CNRS (National Center for Scientific Research) and head of the “Biochemistry of Macromolecular Interactions” unit at Institut Pasteur, Paris, France. He obtained a Ph.D. in Microbiology in 1989 and a « Habilitation à Diriger des Recherches » (HDR), in 1999 from the Université Paris Diderot, Paris, France. His research has been mainly focused on the study of the molecular mechanisms that underlie protein-protein and protein-membrane interactions, using as a model system a bacterial toxin, the adenylate cyclase (CyaA) produced by Bordetella pertussis, the causative agent of whooping cough. CyaA is an essential virulence factor from B. pertussis, and belongs to the large family of RTX (Repeat in ToXins) cytolysins produced by diverse Gram-negative bacteria. By combining molecular genetics, biochemical and biophysical approaches, he has characterized the structure, function and biogenesis of the CyaA toxin, with a particular emphasis on deciphering the molecular basis of its original entry pathway that involves a direct translocation of its catalytic domain across the plasma membrane. Basic knowledge gained on the mechanisms of CyaA entry into eukaryotic target cells and its interaction with cellular effectors has been used to develop various applications in vaccinology and biotechnology. In particular, the natural property of the CyaA toxin to target immune cells has been exploited to create innovative vaccines capable of stimulating potent cell-mediated immune responses against specific antigens. Two CyaA-based recombinant vaccines are currently evaluated in clinical trials. D. Ladant also designed a CyaA-based two-hybrid (BACTH) technology that has been exploited for studying, in bacteria, the assembly of protein complexes, and particularly to analyze membrane associated machineries such as bacterial secretion systems or the bacterial cell division apparatus. His other research interests include the other class II bacterial adenylate cyclase toxins, such as Edema Factor (EF) from Bacillus anthracis and ExoY toxin from Pseudomonas aeruginosa, in particular to explore of the allosteric mechanisms implicated in the activation of these enzymes by eukaryotic factors.

He has published more than 90 articles in peer-reviewed journals, 20 review articles or Book chapters and co-authored 11 patents.
