Imaging of Activated T Cells

Journal of Nuclear Medicine, 2022
The adaptive immune response plays a critical role in detecting, eliminating, and creating a memory toward foreign pathogens and malignant cells. Demonstration of the specific and effective target killing of T cells in cancer has reignited interest in the study and therapeutic manipulation of the interaction between tumor and immune system.

TLR4/CD14/MD2 Revealed as the Limited Toll-like Receptor Complex for Chlamydia trachomatis-Induced NF-κB Signaling

Microorganisms, 2022
Chlamydia trachomatis (Ct) is the most common cause of genital tract infections as well as preventable blindness worldwide. Pattern recognition receptors such as toll-like receptors (TLRs) represent the initial step in recognizing pathogenic ...

Impact of chronic alcohol exposure on conventional and regulatory murine T cell subsets

Frontiers in Immunology, 2023
IntroductionChronic alcohol use poses significant negative consequences to public health and, among its many biologic effects, is associated with significant T cell dysregulation within the adaptive immune system that has yet to be fully characterized ...

Saturated very long-chain fatty acids regulate macrophage plasticity and invasiveness

Journal of Neuroinflammation, 2022
Saturated very long-chain fatty acids (VLCFA, ≥ C22), enriched in brain myelin and innate immune cells, accumulate in X-linked adrenoleukodystrophy (X-ALD) due to inherited dysfunction of the peroxisomal VLCFA transporter ABCD1.

Cell Cycle Entry Control in Naïve and Memory CD8+ T Cells

Frontiers in Cell and Developmental Biology, 2021
CD8+ T cells play important roles in immunity and immuno-oncology. Upon antigen recognition and co-stimulation, naïve CD8+ T cells escape from dormancy to engage in a complex programme of cellular growth, cell cycle entry and differentiation, resulting ...

TNF activity and T cells [PDF]

Cytokine, 2018
TNF (tumor necrosis factor) is both a pro-inflammatory and anti-inflammatory cytokine that is central to the development of autoimmune disease, cancer, and protection against infectious pathogens. As well as a myriad other activities, TNF can be a product of T cells and can act on T cells.

T-cell activation

Trends in Cell Biology, 1992
Activation of T lymphocytes results in immediate intracellular biochemical changes, including increases in cytosolic Ca(2+) levels, stimulation of protein kinase C (PKC) and regulation of protein tyrosine kinases (PTKs). This review describes recent advances in the study of the signalling steps downstream of PKC and PTKs in T cells.

CD95 co-stimulation blocks activation of naive T cells by inhibiting T cell receptor signaling [PDF]

, 2009
CD95 is a multifunctional receptor that induces cell death or proliferation depending on the signal, cell type, and cellular context. Here, we describe a thus far unknown function of CD95 as a silencer of T cell activation.

Not All Immune Checkpoints Are Created Equal

Frontiers in Immunology, 2018
Antibodies that block T cell inhibition via the immune checkpoints CTLA-4 and PD-1 have revolutionized cancer therapy during the last 15 years. T cells express additional inhibitory surface receptors that are considered to have potential as targets in ...

Specific T-cell Activation in an Unspecific T-cell Repertoire [PDF]

Science Progress, 2011
T-cells are a vital type of white blood cell that circulate around our bodies, scanning for cellular abnormalities and infections. They recognise disease-associated antigens via a surface receptor called the T-cell antigen receptor (TCR). If there were a specific TCR for every single antigen, no mammal could possibly contain all the T-cells it needs ...
