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 ...

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

BMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...

The role of Protein Kinase Cη in T cell biology

Frontiers in Immunology, 2012
Protein kinase Cη (PKCη) is a member of the novel PKC subfamily, which also includes δ, ε, and θ isoforms. Compared to the other novel PKCs, the function of PKCη in the immune system is largely unknown.

The immunological synapse balances T cell receptor signaling and degradation.

, 2003
The immunological synapse is a specialized cell-cell junction between T cell and antigen-presenting cell surfaces. It is characterized by a central cluster of antigen receptors, a ring of integrin family adhesion molecules, and temporal stability over ...

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).

Testing the organization of the immunological synapse [PDF]

Current Opinion in Immunology, 2007
Upon encounter with antigen-bearing presenting cells, T cells initiate the formation of a unique junction termed the immunological synapse (IS). The morphology of this junction, characterized in EM as a series of discrete contacts into which are interspersed synaptic spaces [1], has multiple similarities to neuronal synapses.

Nanomaterial‐based immune therapeutic strategies in neurodegenerative diseases

BMEMat, EarlyView.
This review highlights the immunomodulatory potential of nanomaterials (NMs) in treating neurodegenerative diseases (NDs). It focuses on their roles in regulating innate and adaptive immune responses to maintain immune homeostasis. By providing insights into these mechanisms, the review lays the groundwork for innovative NMs therapeutic strategies to ...

Activation-induced polarized recycling targets T cell antigen receptors to the immunological synapse; involvement of SNARE complexes.

, 2004
The mechanism by which T cell antigen receptors (TCR) accumulate at the immunological synapse has not been fully elucidated. Since TCRs are continuously internalized and recycled back to the cell surface, we investigated the role of polarized recycling ...

Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

BMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.
