Modular design of immunological synapses and kinapses.
The concept of an immunological synapse goes back to the early 1980s with the discovery of the relationship between T-cell antigen receptor mediated Ca(2+) signaling, adhesion, and directed secretion. However, this concept did not gain traction until images were published starting in 1998 that revealed a specific molecular pattern in the interface between T cells and model antigen-presenting ce...
متن کاملSubcellular dynamics of T cell immunological synapses and kinapses in lymph nodes.
In vitro studies have revealed that T cell activation occurs during the formation of either dynamic or stable interactions with antigen-presenting cells (APC), and the respective cell junctions have been referred to as immunological kinapses and synapses. However, the relevance and molecular dynamics of kinapses and synapses remain to be established in vivo. Using two-photon imaging, we tracked...
متن کاملCytotoxic immunological synapses.
One of the most fundamental activities of the adaptive immune system is to kill infected cells and tumor cells. Two distinct pathways mediate this process, both of which are facilitated by a cytotoxic immunological synapse. While traditionally thought of as innate immune cells, natural killer (NK) cells are now appreciated to have the capacity for long-term adaptation to chemical and viral insu...
متن کاملComparative Anatomy of Phagocytic and Immunological Synapses
The generation of phagocytic cups and immunological synapses are crucial events of the innate and adaptive immune responses, respectively. They are triggered by distinct immune receptors and performed by different cell types. However, growing experimental evidence shows that a very close series of molecular and cellular events control these two processes. Thus, the tight and dynamic interplay b...
متن کاملCell adhesion molecules and actin cytoskeleton at immune synapses and kinapses.
The immunological synapse is a stable adhesive junction between a polarized immune effector cell and an antigen-bearing cell. Immunological synapses are often observed to have a striking radial symmetry in the plane of contact with a prominent central cluster of antigen receptors surrounded by concentric rings of adhesion molecules and actin-rich projections. There is a striking similarity betw...
