Photosensitization and Redox Signaling

Antioxidants & Redox Signaling, 2000
The effect of light in combination with a chemical or a natural compound is termed photosensitization, and is known to have multiple cellular effects. Among them, modulation of gene expression is one of the most important, because it directly influences cell adaptation to novel environmental conditions.

Redox Signaling in Plants

Antioxidants & Redox Signaling, 2013
Our aim is to deliver an authoritative and challenging perspective of current concepts in plant redox signaling, focusing particularly on the complex interface between the redox and hormone-signaling pathways that allow precise control of plant growth and defense in response to metabolic triggers and environmental constraints and ...

Sodium in Mitochondrial Redox Signaling

Antioxidants & Redox Signaling, 2022
Background: Mitochondrial Na + has been discovered as a new second messenger regulating inner mitochondrial membrane (IMM) fluidity and reactive oxygen species (ROS) production by complex III (CIII). However, the roles of mitochondrial Na

Subcellular Redox Signaling

2017
Oxidative and antioxidative system of cells and tissues maintains a balanced state under physiological conditions. A disruption in this balance of redox status has been associated with numerous pathological processes. Reactive oxygen species (ROS) as a major redox signaling generates in a spatiotemporally dependent manner.

Redox Signaling of Angiogenesis

Antioxidants & Redox Signaling, 2002
Reactive oxygen species (ROS) play a crucial role in vascular angiogenesis. Both in vitro and in vivo studies indicate that angiogenic response in vascular tissue is triggered by ROS signaling in a highly coordinated manner. It appears that massive amounts of ROS produced during ischemia and reperfusion in the vascular tissue, especially in heart ...

Redox regulation of TNF signaling

BioFactors, 1999
AbstractTNF is produced during inflammation and induces, among other activities, cell death in sensitive tumour cells. We previously reported an increased generation of ROS in TNF‐treated L929 fibrosarcoma cells prior to cell death. These ROS are of mitochondrial origin and participate in the cell death process.

Redox Signaling, Neuroinflammation, and Neurodegeneration

Antioxidants & Redox Signaling, 2018
Production of pro-inflammatory and anti-inflammatory cytokines is part of the defense system that mostly microglia and macrophages display to induce normal signaling to counteract the deleterious actions of invading pathogens in the brain. Also, redox activity in the central nervous system (CNS) constitutes an integral part of the metabolic processes ...

Redox Regulation of Cellular Signalling

Cellular Signalling, 1999
Extracellular stimuli elicit a variety of responses, such as cell proliferation and differentiation, through the cellular signalling system. Binding of growth factors to the respective receptor leads to the activation of receptor tyrosine kinases, which in turn stimulate downstream signalling systems such as mitogen-activated protein (MAP) kinases ...

Redox-signals and macrophage biology

Molecular Aspects of Medicine, 2018
Macrophages are known for their versatile role in biology. They sense and clear structures that contain exogenous or endogenous pathogen-associated molecular patterns. This process is tightly linked to the production of a mixture of potentially harmful oxidants and cytokines.

Lipid Rafts and Redox Signaling

Antioxidants & Redox Signaling, 2007
In addition to the amplifying action of enzymes in the cell-signaling cascade, another important mechanism has been shown to amplify the signals massively when ligands bind to their receptors, which is characterized by clustering of membrane lipid microdomains or lipid rafts and formation of various signaling platforms.
