WebReactive oxygen species are also formed as necessary intermediates in a variety of enzyme reactions. Examples of situations in which oxygen radicals are overproduced in cells include: White blood cells such as neutrophils specialize in producing oxygen radicals, which are used in host defense to kill invading pathogens. WebReactive oxygen species (ROS) are well known for their role in mediating both physiological and pathophysiological signal transduction. Enzymes and subcellular compartments that typically produce ROS are associated with metabolic regulation, and diseases associated with metabolic dysfunction may be influenced by changes in redox balance.
WebMar 8, 2024 · S100B is an astrocytic cytokine that has been shown to be involved in several neurodegenerative diseases. We used an astrocytoma cell line (U373 MG) silenced for S100B, and stimulated it with amyloid beta-peptide (Aβ) as a known paradigm factor for astrocyte activation, and showed that the ability of the cell (including the gene machinery) … WebActive species in the polymerization of cyclic acetals undergo fast isomerization, as already discussed in Section 49.4.2.1.ii.This results in chain transfer to polymer, i.e. formation (by …
