The Immune Synapse as a Novel Target for Therapy [Hardcover]

This volume gives an overview on the progress in immune synapse research, from basic science to clinical trials, and the major mechanisms involved. It discusses how interfering with T cell activation may lead to immune tolerance, immune modulation, and the recruitment of regulatory T cells; the role of monoclonal antibodies in tolerance induction; and mechanisms maintaining dominant tolerance.

It is now accepted that T cell activation by an antigen-presenting cell requires the organization of a supramolecular structure  the immune synapse. This structure, with different types of molecules spatially segregated, is involved in the delivery of quantitative and qualitative signals critical for T cell activation, and therefore in controlling the nature of the immune response. This volume discusses the progress in manipulating components of the immune synapse as a strategy to regulate the immune response in immune pathology, such as transplantation, autoimmunity and allergy. Donnadieu reviews the current knowledge on the molecular composition and organization of the immune synapse and how the formation of this structure can be modulated by chemokines. It is also known that the immune synapse formation is critical for the activation of naive T cells, as well as their functional polarization. The second chapter discusses the conversion of naive T cells into regulatory T cells (Treg) when components of the immune synapse are manipulated in such a way that the T cells receive suboptimal activation signals.The immune synapse and T cell activation: regulation by chemokines.- The induction of regulatory T cells by targeting the immune synapse.- Infiltrating the immunological synapse: prospects for the use of altered petide ligands for the treatment of immune pathology.- Targeting CD4 for the induction of dominant tolerance.- Anti-CD3: from T cell depletion to tolerance induction.- Immune modulation by CD40L blockade.- CTLA-4-Ig and indoleamine 2,3-dioxygenase lc)
