HIV-1 intersection with CD4 T cell vesicle exocytosis: intercellular communication goes viral

open access: yesFrontiers in Immunology, 2014
In cells of the immune system the secretion of extracellular vesicles is modulated through cellular activation. In particular, T cell activation is achieved through cell-cell contacts with antigen presenting cells and the consequent formation of a ...

Information transfer at the immunological synapse [PDF]

open access: bronzeCurrent Biology, 2000
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 ...

Modulation of Host Immunity by Human Respiratory Syncytial Virus Virulence Factors: A Synergic Inhibition of Both Innate and Adaptive Immunity [PDF]

open access: yes, 2017
Indexación: Web of Science; Scopus.The Human Respiratory Syncytial Virus (hRSV) is a major cause of acute lower respiratory tract infections (ARTIs) and high rates of hospitalizations in children and in the elderly worldwide.

HIV-1 Virological Synapse is not Simply a Copycat of the Immunological Synapse

open access: yesViruses, 2010
The virological synapse (VS) is a tight adhesive junction between an HIV-infected cell and an uninfected target cell, across which virus can be efficiently transferred from cell to cell in the absence of cell-cell fusion.

T-Cell activation: a queuing theory analysis at low agonist density [PDF]

open access: yes, 2006
We analyze a simple linear triggering model of the T-cell receptor (TCR) within the framework of queuing theory, in which TCRs enter the queue upon full activation and exit by downregulation.

Actin Engine in Immunological Synapse [PDF]

open access: yesImmune Network, 2012
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.

Spatial Organization of the Cytoskeleton enhances Cargo Delivery to Specific Target Areas on the Plasma Membrane of Spherical Cells [PDF]

open access: yes, 2016
Intracellular transport is vital for the proper functioning and survival of a cell. Cargo (proteins, vesicles, organelles, etc.) is transferred from its place of creation to its target locations via molecular motor assisted transport along cytoskeletal ...

An Effective Membrane Model of the Immunological Synapse

open access: yes, 2003
The immunological synapse is a patterned collection of different types of receptors and ligands that forms in the intercellular junction between T Cells and antigen presenting cells (APCs) during recognition.

Orchestration of Immunological Synapse Assembly by Vesicular Trafficking

open access: yesFrontiers in Cell and Developmental Biology, 2019
Ligation of the T-cell antigen receptor (TCR) by cognate peptide bound to the Major Histocompatibility Complex on the surface of an antigen-presenting cell (APC) leads to the spatial reorganization of the TCR and accessory receptors to form a specialized

The immune synapses reveal aberrant functions of CD8 T cells during chronic HIV infection

open access: yesNature Communications, 2022
HIV infection over time is thought to result in premature aging and aberrant immune responses including the induction of immunological senescence. Here the authors show altered formation of immune synapses by naive CD8+ T cells and dysregulated synapse ...
