Costimulation: Building an Immunological Synapse

Science, 1999
Immune responses are triggered by activation of the T cell receptor with foreign antigen. Dustin summarizes in his Perspective new evidence that this triggering event is actually the formation of an "immunological synapse," an area of close contact between cells. Recent results ( Viola et al.

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia

Advanced Science, EarlyView.
Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

Imaging Membrane Curvature inside a FcεRI-Centric Synapse in RBL-2H3 Cells Using TIRF Microscopy with Polarized Excitation

Journal of Imaging, 2019
Total internal reflection fluorescence microscopy with polarized excitation (P-TIRF) can be used to image nanoscale curvature phenomena in live cells. We used P-TIRF to visualize rat basophilic leukemia cells (RBL-2H3 cells) primed with fluorescent anti ...

Ultrasound‐Activated Piezoelectric Neuroimmune Hydrogel Orchestrates Neurogenesis‐Macrophage Crosstalk in Diabetic Wound Healing

Advanced Science, EarlyView.
In this work, we design an ultrasound‐activated piezoelectric hydrogel platform (AOEF@AP5+US) that reprograms neurogenesis‐macrophage crosstalk as an integrated strategy to overcome the intertwined barriers of chronic inflammation, peripheral neuropathy, and impaired regeneration in diabetic wounds.

Modulation of Tumor Immunity by Soluble and Membrane-Bound Molecules at the Immunological Synapse

Clinical and Developmental Immunology, 2013
To circumvent pathology caused by infectious microbes and tumor growth, the host immune system must constantly clear harmful microorganisms and potentially malignant transformed cells. This task is accomplished in part by T-cells, which can directly kill

The dendritic cell synapse: a life dedicated to T cell activation

Frontiers in Immunology, 2016
T cell activation within immunological synapses is a complex process whereby different types of signals are transmitted from antigen presenting cells to T cells.

The Immunological Synapse--a Multitasking System

Science, 2002
The immunological synapse, the interface between the T cell and antigen-presenting cell (APC), is thought to be important for enhancing and sustaining signaling by the T cell receptor after it has engaged antigenic peptide on the APC surface. In a Perspective, van der Merwe and Davis discuss new findings ( Lee et al.) demonstrating ...

Hypothalamic Control of Liver Health and Disease: From Circuits to Pathophysiology and Therapies

Advanced Science, EarlyView.
This review delineates the hypothalamic circuits that control liver homeostasis via autonomic and neuroendocrine pathways. Dysregulation of this hypothalamus–liver axis drives disease progression across a spectrum including steatotic liver disease, liver inflammation and injury, fibrosis, cirrhosis, and hepatocellular carcinoma.

Interplay of channels, pumps and organelle location in calcium microdomain formation

New Journal of Physics, 2013
To analyze the influence of Ca ^2+ microdomains on the global cytosolic Ca ^2+ concentration, we consider the polarization and activation of T-cells after the formation of an immunological synapse as a model system.

A dynamic view of the immunological synapse

Seminars in Immunology, 2005
T cell activation requires interactions of T cell antigen receptors (TCR) and peptides presented by major histocompatibility complex molecules (MHCp) in an adhesive junction between the T cell and antigen-presenting cell. Stable junctions with bull's eye supramolecular activation clusters (SMACs) have been defined as immunological synapses (IS).
