RhoH regulates subcellular localization of ZAP-70 and Lck in T cell receptor signaling. [PDF]

open access: yesPLoS ONE, 2010
RhoH is an hematopoietic-specific, GTPase-deficient Rho GTPase that plays a role in T development. We investigated the mechanisms of RhoH function in TCR signaling. We found that the association between Lck and CD3ζ was impaired in RhoH-deficient T cells,

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 ...

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.

Rosetting T cells in Hodgkin lymphoma are activated by immunological synapse components HLA class II and CD58.

open access: yesBlood, 2020
A unique feature of Hodgkin lymphoma (HL) is the presence of CD4+ T cells that surround, protect and promote survival of tumor cells. The adhesion molecules involved in this so-called T cell rosetting are important components of the immunological synapse

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.

T lymphocyte myosin IIA is required for maturation of the immunological synapse

open access: yesFrontiers in Immunology, 2012
The role of non-muscle myosin IIA (heavy chain encoded by the non-muscle myosin heavy chain 9 gene, Myh9) in immunological synapse formation is controversial.

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 ...

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 ...

Altered actin centripetal retrograde flow in physically restricted immunological synapses.

open access: yesPLoS ONE, 2010
Antigen recognition by T cells involves large scale spatial reorganization of numerous receptor, adhesion, and costimulatory proteins within the T cell-antigen presenting cell (APC) junction.

Actin foci facilitate activation of the phospholipase C-γ in primary T lymphocytes via the WASP pathway

open access: yeseLife, 2015
Wiscott Aldrich Syndrome protein (WASP) deficiency results in defects in calcium ion signaling, cytoskeletal regulation, gene transcription and overall T cell activation. The activation of WASP constitutes a key pathway for actin filament nucleation. Yet,
