The 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 کاملActin Engine in Immunological Synapse
T cell activation and function require physical contact with antigen presenting cells at a specialized junctional structure known as the immunological synapse. Once formed, the immunological synapse leads to sustained T cell receptor-mediated signalling and stabilized adhesion. High resolution microscopy indeed had a great impact in understanding the function and dynamic structure of immunologi...
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...
متن کاملImmunological Synapse Molecules
Immunological Synapse (IS) is a multi-molecular assembly functional structure formed at the interface of T lymphocyte and antigen presenting cell. These molecules include antigen presenting molecules, adhesion molecules, co-stimulatory molecules, and inhibitors or checkpoint molecules, etc. The spatial and temporal changes of these molecules determine the structure type and the function of the ...
متن کاملImmunological synapse arrays: patterned protein surfaces that modulate immunological synapse structure formation in T cells.
T cells are activated by recognition of foreign peptides displayed on the surface of antigen presenting cells (APCs), an event that triggers assembly of a complex microscale structure at the T cell-APC interface known as the immunological synapse (IS). It remains unresolved whether the unique physical structure of the synapse itself impacts the functional response of T cells, independent of the...
