This book intends to assemble reviews on the progress in defining and controlling the spatiotemporal organization of key events in immune cell activation. Improved understanding of MIRR-mediated signaling has a number of potential practical applications, from the rational design of drugs and vaccines to the engineering of cells for biotechnological purposes. In Section 1, spatial organization and physiological function of the MIRR family members such as T cell receptor (TCR), B cell receptor (BCR), Fc receptors, natural killer (NK) cell receptors, and platelet glycoprotein VI (GPVI) will be reviewed. Section 2 will focus on current models of MIRR-triggering and highlight modern technologies to visualize cell-cell interaction contacts such as immunological synapse and to measure protein-protein interactions in space in real time. Potential therapeutic strategies targeting the MIRR-mediated transmembrane signal transduction will be shortly reviewed in Section 3. This book will summarize our current knowledge in this field and illustrate how control of the MIRR-triggered signaling could become a potential target of medical intervention, thus bridging basic and clinical immunology.

About the Author

ALEXANDER SIGALOV, PhD, is a Research Assistant Professor in the Department of Pathology at the University of Massachusetts Medical School in Worcester, Massachusetts, USA. His main research interests include protein intrinsic disorder and oligomericity in the context of transmembrane signal transduction, the molecular mechanisms underlying immune receptor-mediated signaling and ways to control these processes and thus to modulate the immune response, as well as the development and applications of novel targets and strategies for innovative immune therapy. He discovered and investigated a very unusual and unique biophysical phenomenon, the homooligomerization of intrinsically disordered proteins, thus providing the first evidence for the existence of specific interactions between unfolded protein molecules. In the field of immunology, he unraveled a long-standing mystery of transmembrane signaling and immune cell activation triggered by multichain immune recognition receptors. Later, he developed a novel concept of platelet inhibition and invented a novel class of platelet inhibitors. In the field of immune therapy, he proposed new therapeutic strategies for a variety of malignancies and immune disorders, including immunodeficiencies, inflammatory and autoimmune diseases, allergy and HIV. He is a member of the American Association for the Advancement of Science and the Biophysical Society, USA. Alexander Sigalov received his academic degrees (MSc in Chemistry and a PhD in Organic Chemistry) from Moscow State University, Russia.
