The role of PD-1 signaling in health and immune-related diseases

open access: yesFrontiers in Immunology, 2023
Programmed cell death 1 receptor (PD-1) and its ligands constitute an inhibitory pathway to mediate the mechanism of immune tolerance and provide immune homeostasis.

PD-L1 Co-Stimulation Contributes to Ligand-Induced T Cell Receptor Down-Modulation on \(CD8^+\) T Cells [PDF]

open access: yes, 2013
T cell receptor (TCR) down-modulation after antigen presentation is a fundamental process that regulates TCR signal transduction. Current understanding of this process is that intrinsic TCR/CD28 signal transduction leads to TCR down-modulation.

Cleavage of DFNA5 by caspase-3 during apoptosis mediates progression to secondary necrotic/pyroptotic cell death. [PDF]

open access: yes, 2017
Apoptosis is a genetically regulated cell suicide programme mediated by activation of the effector caspases 3, 6 and 7. If apoptotic cells are not scavenged, they progress to a lytic and inflammatory phase called secondary necrosis.

Immune checkpoint inhibitors in renal cell carcinoma [PDF]

open access: yes, 2017
The immune system has long been known to play a critical role in the body's defence against cancer, and there have been multiple attempts to harness it for therapeutic gain.

Gut Microbiota Modulates the Efficiency of Programmed Cell Death Protein 1 Cancer Immunotherapies

open access: yesIranian Journal of Allergy, Asthma and Immunology, 2022
Program cell death protein 1 (PD1) is considered as an inhibitory molecule that is expressed on the surface of activated T-cells and bound to PD-L1 and PD-L2 ligands.

The Value of Programmed Death Ligand 1 Expression in Cancer Patients Treated with Neoadjuvant Chemotherapy

open access: yesSultan Qaboos University Medical Journal, 2019
Programmed death ligand 1 (PD-L1) is an inhibitory molecule expressed by cancer cells to supress T-cell activity and escape anti-tumour immunity. The role of PD-L1 in cancer has been studied extensively as it is considered an important immune checkpoint ...

Reversal of an immunity associated plant cell death program by the growth regulator auxin [PDF]

open access: yes, 2007
One form of plant immunity against pathogens involves a rapid host programmed cell death at the site of infection accompanied by resistance, termed the hypersensitive response (HR).

Research Progress of Anti-PD-1/PD-L1 Therapy for Non-small Cell Lung Cancer 
with EGFR Mutation

open access: yesChinese Journal of Lung Cancer, 2022
The use of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) is the first line treatment for EGFR-mutant advanced non-small cell lung cancer (NSCLC), but drug resistance will be acquired within 1-2 years, and the following treatment

Anti-programmed cell death protein-1/ligand-1 therapy in different cancers. [PDF]

open access: yes, 2015
Immunologic checkpoint blockade with antibodies against the programmed cell death protein-1 (PD-1) or its ligand (PD-L1) is an effective method for reversing cancer immunosuppression and thereby promoting immune responses against several cancer types ...

The Molecular Links between Cell Death and Inflammasome

open access: yesCells, 2019
Programmed cell death pathways and inflammasome activation pathways can be genetically and functionally separated. Inflammasomes are specialized protein complexes that process pro-inflammatory cytokines, interleukin-1β (IL-1β), and IL-18 to ...
