This high severity is dependent on a cytokine storm, most likely induced by the interleukin-6 (IL-6) amplifier, which is hyper-activation machinery that regulates the nuclear factor kappa B (NF-魏B) pathway and stimulated by the simultaneous activation of IL-6-signal transducer and activator ...
L’atteinte des personnels de santé a été moins forte que ce qui avait été observé lors des épidémies précédentes, notamment lors du SRAS de 2003, marquée par une grande hétérogénéité de la transmission. Il a fallu attendre au moins 5 jours pour 89 % des sujets avant qu’i...
For example, a key role of anaphylatoxin C5a as an amplifier of the septic inflammatory response [[44] has been reported in COVID-19 [45]. Similarly, a deleterious synergy between tumor necrosis factor (TNF) and interferon (IFN)-γ , originally reported to explain lethality in response to...
Among the increased levels of inflammatory mediators in COVID-19 patients, the plasma levels of IL-6, an amplifier in the cytokine storm, are significantly elevated in non-survivors compared with survivors (5). The main cause of death of COVID-19 is due to severe acute respiratory distress ...

This finding strongly suggests an amplifier role for IL-17A in the inflammatory response, since it triggers the production of other pro-inflammatory cytokines i.e. IL-1, IL-6, TNF-α [17]. Furthermore, the decrease in lymphocytic population subsets, coupled with the rise in Th17 cells and...
LSPR-coupled fluorescence with AuNPs as an amplifier has also been introduced to detect the nucleocapsid protein (N protein) of SARS-CoV with a linear range from 0.1 pg/mL to 1 ng/mL.249In addition, a dual-functional nanobiosensor integrated on a chip with two-dimensional nanoabsorbers...
Interleukin-17A (IL-17A): A silent amplifier of COVID-19 2021, Biomedicine and Pharmacotherapy Citation Excerpt : This clinical evidence is of particular importance since IL-17A induces the production of other pro-inflammatory mediators such as IL-1, IL-6, TNF-α that, together with matrix me...
