What is the importance of the immunological synapse? [PDF]
Trends in Immunology, 2004 The immunological synapse (IS) has proved to be a stimulating concept, particularly in provoking discussion on the similarity of intercellular communication controlling disparate biological processes. Recent studies have clarified some of the underlying molecular mechanisms and functions of the IS.

Communication, the centrosome and the immunological synapse [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2014 Recent findings on the behaviour of the centrosome at the immunological synapse suggest a critical role for centrosome polarization in controlling the communication between immune cells required to generate an effective immune response. The features observed at the immunological synapse show parallels to centrosome (basal body) polarization seen in ...

Active tuning of synaptic patterns enhances immune discrimination [PDF]
Phys. Rev. Lett. 121, 238101 (2018), 2018 Immune cells learn about their antigenic targets using tactile sense: during recognition, a highly organized yet dynamic motif, named immunological synapse, forms between immune cells and antigen-presenting cells (APCs). Via synapses, immune cells selectively extract recognized antigen from APCs by applying mechanical pulling forces generated by the ...

Frontiers in Endocrinology, 2019 Based on the work in the Central Nervous System with discoveries of allosteric receptor-receptor interactions in homo- and heteroreceptor complexes representing a major integrative mechanism in synapses and extrasynaptic regions, it is proposed that a ...

Close Contact Fluctuations: Time of Contact [PDF]
Physical Review E 90, 042706 (2014), 2014 The letter resolves the long standing debate as to the proper time scale ($<\tau>$) of the onset of the immunological synapse (IS) bond, the non-covalent chemical bond defining the immune pathways involving T-cells and antigen presenting cells (APC).

ICAM-1 depletion in the center of immunological synapses is important for calcium releasing in T-cells [PDF]
Journal of Innovative Optical Health Sciences, 2018 T-cell activation requires the formation of the immunological synapse (IS) between a T-cell and an antigen-presenting cell (APC) to control the development of the adaptive immune response. However, calcium release, an initial signal of T-cell activation,

Stochastic model of T Cell repolarization during target elimination (I) [PDF]
, 2020 Cytotoxic T lymphocytes (T) and natural killer (NK) cells are the main cytotoxic killer cells of the human body to eliminate pathogen-infected or tumorigenic cells (i.e. target cells). Once a NK or T cell has identified a target cell, they form a tight contact zone, the immunological synapse (IS).

What Counts in the Immunological Synapse? [PDF]
Molecular Cell, 2014 Molecular interactions at the interface between helper T cells and antigen-presenting B cells govern the ability to produce specific antibodies, which is a central event in protective immunity generated by natural infection or man-made vaccines. In order for a T cell to deliver effective help to a B cell and guide affinity maturation, it needs to ...

BMC Biology, 2011 Background Cytolytic cells of the immune system destroy pathogen-infected cells by polarised exocytosis of secretory lysosomes containing the pore-forming protein perforin. Precise delivery of this lethal hit is essential to ensuring that only the target

Haematologica, 2011 Background T-cell activation relies on the assembly of the immunological synapse, a structure tightly regulated by the actin cytoskeleton. The precise role of the Wiskott-Aldrich syndrome protein, an actin cytoskeleton regulator, in linking immunological
