Identification of distinct cytotoxic granules as the origin of supramolecular attack particles in T lymphocytes

open access: yesNature Communications, 2022
Cytotoxic T cells have specialised granules that are important for mediating their killing function. Here the authors characterise two types of cytotoxic granules and indicate different functions and temporal release of mediators at the immunological ...

Lipid switches in the immunological synapse. [PDF]

open access: yesJ Biol Chem
Adaptive immune responses comprise the activation of T cells by peptide antigens that are presented by proteins of the Major Histocompatibility Complex (MHC) on the surface of an antigen-presenting cell. As a consequence of the T cell receptor interacting productively with a certain peptide-MHC complex, a specialized cell-cell junction known as the ...

Distinct structural and catalytic roles for Zap70 in formation of the immunological synapse in CTL

open access: yeseLife, 2014
T cell receptor (TCR) activation leads to a dramatic reorganisation of both membranes and receptors as the immunological synapse forms. Using a genetic model to rapidly inhibit Zap70 catalytic activity we examined synapse formation between cytotoxic T ...

Action and traction: cytoskeletal control of receptor triggering at the immunological synapse

open access: yesFrontiers in Immunology, 2016
It is well known that F-actin dynamics drive micron-scale cell shape changes required for migration and immunological synapse formation. In addition, recent evidence points to a more intimate role for the actin cytoskeleton in promoting T cell activation.

The Roles of Membrane Rafts in CD32A-Mediated Phagocytosis [PDF]

open access: yes, 2007
Membrane rafts are highly dynamic heterogeneous sterol- and sphingolipid-rich micro-domains on cell surfaces. They are generally believed to provide residency for cell surface molecules (e.g., adhesion and signaling molecules) and scaffolding to ...

In vitro Assessment of Immunological Synapse Formation by Flow Cytometry

open access: yesBio-Protocol, 2016
In adaptive immune system, formation of immunological synapse between T cells and antigen presenting cells (dendritic cells, B cells, and macrophages) or target cells (tumor cells and viral-infected cells) is critical for the execution of T cell immune ...

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,

Imaging the Human Immunological Synapse [PDF]

open access: yesJournal of Visualized Experiments, 2019
The purpose of the method is to generate an immunological synapse (IS), an example of cell-to-cell conjugation formed by an antigen-presenting cell (APC) and an effector helper T lymphocyte (Th) cell, and to record the images corresponding to the first stages of the IS formation and the subsequent trafficking events (occurring both in the APC and in ...
