Discovery of the first PD-1 ligand encoded by a pathogen

Frontiers in Immunology, 2022
Large double-stranded DNA viruses deploy multiple strategies to subvert host immune defenses. Some of these tactics are mediated by viral gene products acquired by horizontal gene transfer from the corresponding hosts and shaped throughout evolution. The

T Cell Activation and the Cytoskeleton

Annual Review of Immunology, 2000
Ligation of the T cell antigen receptor (TCR) stimulates protein tyrosine kinases (PTKs), which regulate intracellular calcium and control the activity of protein kinase C (PKC) isozymes. PTKs activated by antigen receptors and costimulatory molecules also couple to phosphatidylinositol-3 kinase (PI3K) and control the activity of Ras- and Rho-family ...

Brain endothelial miR-146a negatively modulates T-cell adhesion through repressing multiple targets to inhibit NF-κB activation. [PDF]

, 2014
Pro-inflammatory cytokine-induced activation of nuclear factor, NF-κB has an important role in leukocyte adhesion to, and subsequent migration across, brain endothelial cells (BECs), which is crucial for the development of neuroinflammatory disorders ...

Tethering of vesicles to the Golgi by GMAP210 controls LAT delivery to the immune synapse

Nature Communications, 2019
The immune synapse at the interface between T cells and antigen-presenting cells manifests intense vesicular trafficking, but how the vesicles are sorted is still unclear.

The transcriptional activator Gli2 modulates T-cell receptor signalling through attenuation of AP-1 and NFκ-B activity. [PDF]

, 2015
Different tissues contain diverse and dynamic cellular niches, providing distinct signals to tissue-resident or migratory, infiltrating immune cells.

Neuropilin-1 Acts as a Receptor for Complement Split Products

Frontiers in Immunology, 2019
Complement split products (CSPs), such as the fragments C4d and C3d, which are generated as a consequence of complement regulatory processes, are established markers for disease activity in autoimmunity or antibody-mediated graft rejection.

T Cell Membrane Heterogeneity Aids Antigen Recognition and T Cell Activation

Frontiers in Cell and Developmental Biology, 2020
T cells are critical for co-ordinating the immune response. T cells are activated when their surface T cell receptors (TCRs) engage cognate antigens in the form of peptide-major histocompatibility complexes (pMHC) presented on the surface of antigen ...

T-cell activation without proliferation in juvenile idiopathic arthritis [PDF]

, 2002
A study was done to determine if the differentiation and activation phenotype of T cells in synovial fluid (SF) from patients with juvenile idiopathic arthritis (JIA) is associated with T-cell proliferation in situ.

T-Cell activation: a queuing theory analysis at low agonist density [PDF]

, 2006
We analyze a simple linear triggering model of the T-cell receptor (TCR) within the framework of queuing theory, in which TCRs enter the queue upon full activation and exit by downregulation.

PD-1 Blockade Promotes Emerging Checkpoint Inhibitors in Enhancing T Cell Responses to Allogeneic Dendritic Cells

Frontiers in Immunology, 2017
Immune checkpoint inhibitors, which target coinhibitory T cell molecules to promote anticancer immune responses, are on the rise to become a new pillar of cancer therapy.
