The role of the cytoskeleton at the immunological synapse [PDF]

Immunological Reviews, 2013
SummaryIt has been over 30 years since the reorganization of both the microtubule network and a ‘peculiar actin polarization’ was reported at the contact area of cytotoxic T lymphocytes interacting with target cells. Since that time, hundreds of studies have been published in an effort to elucidate the structure and function of the microtubule network ...

Altered actin centripetal retrograde flow in physically restricted immunological synapses.

PLoS 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.

Stomatin-like Protein 2 Links Mitochondria to T-Cell Receptor Signalosomes at the Immunological Synapse and Enhances T-Cell Activation [PDF]

, 2007
T cell activation through the antigen receptor (TCR) requires sustained signalling from microclusters in the peripheral region of the immunological synapse (IS).

Electroencephalographic Normalization as a Biomarker of Clinical Recovery in Down Syndrome Regression Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Down syndrome regression disorder is a syndrome characterized by subacute loss of cognitive, behavioral, and functional abilities in individuals with Down syndrome. Electroencephalography abnormalities are frequently observed during evaluation, but it remains unclear whether these findings represent a dynamic marker of disease ...

Paramagnetic Rim Lesions and Choroid Plexus Volume at Diagnosis Are Associated With Cognitive Progression Independent of Relapse and MRI Activity in Early Relapsing–Remitting Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Paramagnetic rim lesions (PRLs) and choroid plexus (CP) enlargement reflect smoldering inflammation in multiple sclerosis. Their role in cognitive progression remains unexplored. Eighty‐seven early relapsing–remitting MS patients were enrolled at diagnosis and followed longitudinally.

NKp46 clusters at the immune synapse and regulates NK cell polarization

Frontiers in Immunology, 2015
Natural killer cells play an important role in first-line defense against tumor and virus-infected cells. The activity of NK cells is tightly regulated by a repertoire of cell-surface expressed inhibitory and activating receptors.

A role for TASK2 channels in the human immunological synapse

, 2020
The immunological synapse is a transient junction that occurs when the plasma membrane of a T cell comes in close contact with an APC after recognizing a peptide from the antigen-MHC.

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

eLife, 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,

How is Nanoarchitectonics Shaping Extracellular Vesicle Research?

Advanced Healthcare Materials, EarlyView.
The convergence of nanoarchitectonics and extracellular vesicle biology is reshaping next‐generation nanomedicine by enabling rationally designed nanostructures for enhanced EVs detection, engineering, and therapy. ABSTRACT Extracellular vesicles (EVs) have gained recognition as crucial mediators of cell‐to‐cell communication, holding immense potential

LIM and SH3 protein 1 deficiency confers resistance to cytotoxic lymphocyte-mediated lysis and immunotherapy in gastric cancer by disrupting cytoskeleton dynamics

Journal for ImmunoTherapy of Cancer
Background A substantial amount of research has been dedicated to the mechanisms by which tumor cells evade immune system recognition and manipulate the immune microenvironment to facilitate immune escape.
