Information transfer at the immunological synapse
Antigen-specific activation of T lymphocytes requires the interaction of their clonally distributed T-cell receptors with plasma membrane ligands composed of foreign peptide antigens bound to major histocompatibility complex molecules. For proliferation and differentiation to ensue, a variety of other adhesive and accessory proteins must also interact with their counter-receptors on the antigen...
متن کاملIntercellular Transfer of Oncogenic H-Ras at the Immunological Synapse
Immune cells establish dynamic adhesive cell-cell interactions at a specific contact region, termed the immunological synapse (IS). Intriguing features of the IS are the formation of regions of plasma membrane fusion and the intercellular exchange of membrane fragments between the conjugated cells. It is not known whether upon IS formation, intact intracellular proteins can transfer from target...
متن کاملEditorial: Molecular Dynamics at the Immunological Synapse
The immunological synapse (IS) is a specialized cell–cell adhesion that mediates antigen acquisition , lymphocyte activation, and effector function. Seminal studies showed a structure composed of stable central and peripheral supramolecular activation clusters (cSMAC and pSMAC) organized at the interface of interacting helper T lymphocytes and B lymphocytes. The T cell receptor (TCR) and signal...
متن کاملThe Immunological Synapse T. Klemmensen: The Immunological Synapse
The induction of a proper adaptive immune response is dependent on the correct transfer of information between antigen-presenting cells (APCs) and antigen-specific T cells. Defects in information transfer may result in the development of diseases, e.g. immunodeficiencies and autoimmunity. A distinct 3-dimensional supramolecular structure at the T cell/APC interface has been suggested to be invo...
متن کاملThe immunological synapse
T-cell activation requires interaction of T-cell antigen receptors with proteins of the major histocompatibility complex (antigen). This interaction takes place in a specialized cell-cell junction referred to as an immunological synapse. The immunological synapse contains at least two functional domains: a central cluster of engaged antigen receptors and a surrounding ring of adhesion molecules...
