Arrestins - Pharmacology and Therapeutic Potential
This volume describes our current understanding of the biological role of visual and non-visual arrestins in different cells and tissues, focusing on the mechanisms of arrestin-mediated regulation of GPCRs and non-receptor signaling proteins in health and disease. The book covers wide range of arrestin functions, emphasizing therapeutic potential of targeting arrestin interactions with individual partners.
The Molecular Biology of Arrestins
This special volume of Progress in Molecular Biology and Translational Science focuses on the molecular biology of arrestins, with contributions from leaders in the field. Arrestins have emerged as central players in the regulation of many facets of G protein-coupled receptor signaling. This volume covers a variety of topics with reviews written by experts in the field. - Contributions from leading authorities - Informs and updates on all the latest developments in the field
Peptidergic G Protein-coupled Receptors
Peptides are a rapidly growing class of mediators whose activity regulates homeostasis as well as pathological processes. Most of the peptide-activated receptors belong to the superfamily of 7 transmembrane domain receptors coupled to G proteins. Peptides of different sizes (from a few to more than 100 aminoacids) activate peptidergic receptors by interacting at specific sites, that often differ from those where antagonists bind. Other receptors are activated by proteases that, by cleaving the receptor extracellular region, unmask a tethered ligand. G protein-coupled receptors for chemokines represent the way of entry of the HIV virus in target cells. The great impact of non peptide agonist/antagonists in current and future medicine reflects these large variety of functions and modes of activation of peptidergic G protein-coupled receptors.
Proteases and Their Receptors in Inflammation
Proteases are everywhere from prokaryotes to eukaryotes, from virus to bacteria and in all human tissues, playing a role in many biological functions. Among these functions, the inflammatory reaction is of particular interest. In inflamed tissues, proteases can have a microbial and/or host origin and are involved not only in tissue remodeling, but also in specific signaling to resident or inflammatory cells, thereby contributing to the innate immune response. This volume presents all advances in our knowledge of the role proteases and their inhibitors play in various diseases associated with inflammatory response. Mechanisms involved in protease signaling to cells are presented, and the different types of proteases that are present at inflammatory sites and their effects on the course of inflammation are discussed. Finally, the evidence for considering proteases and their receptors as potential molecular targets for therapeutic interventions in the treatment of inflammatory diseases is discussed in the context of specific organ inflammatory pathologies (the lung, gastrointestinal tract, skin, joints, etc.).
