Dynamics and spatial organization of Kv1.3 at the immunological synapse of human CD4+ T cells.

Formation of the immunological synapse (IS) is a key event during initiation of an adaptive immune response to a specific antigen. During this process, a T cell and an antigen presenting cell form a stable contact that allows the T cell to integrate both internal and external stimuli in order to decide whether to activate. The threshold for T cell activation depends on the strength and frequency of the calcium (Ca) signaling induced by antigen recognition, and it must be tightly regulated to avoid undesired harm to healthy cells.
